Product Description, Indications for Use,
Contraindications, and Features
The following chapter contains the Radical-7 product description, key features and benefits,
indications for use, contraindications, and safety information, including cautions, warnings,
and notes.
Product Description
The Radical-7 is a noninvasive monitor that measures arterial oxygen saturation (SpO2),
pulse rate, and perfusion index (PI), along with optional measurements of hemoglobin
(SpHb), carboxyhemoglobin (SpCO), methemoglobin (SpMet), Pleth Variability Index (PVI),
Acoustic Respiration Rate (RRa), and Pleth Respiration Rate (RRp) .
The Radical-7 can be used as either a Handheld or a Standalone monitor. The Radical-7
features a touchscreen Liquid Crystal Display (LCD) that continuously displays numeric
values for all parameters.
The Radical-7 provides graphical displays for plethysmographic waveform, respiratory
waveform, Signal Identification and Quality Indicator (Signal IQ).
The Radical-7 can also be used to interface with a multi-parameter patient monitor to send
Masimo SET pulse oximetry information to that monitor for display.
The Radical-7 has an embedded 802.11 wireless radio that can be used for connectivity.
Key Features
The following features are available for the Radical-7. Some features are optional:
Masimo SET is clinically proven to satisfy all sensitivity and specificity
requirements for pulse oximeter technology.
Rainbow technology uses 7+ wavelengths of light to continuously and
noninvasively measure carboxyhemoglobin (SpCO), methemoglobin (SpMet), and
total hemoglobin (SpHb), as well as providing a more reliable probe-off
detection.
Total oxygen content (SpOC) provides a calculated measurement of the amount
of oxygen in arterial blood, which may provide useful information about oxygen
both dissolved in plasma and combined with hemoglobin.
Perfusion Index (PI) with trending capability indicates arterial pulse signal
strength and may be used as a diagnostic tool during low perfusion.
Pleth Variability Index (PVI) may show changes that reflect physiologic factors
such as vascular tone, circulating blood volume, and intrathoracic pressure
excursions.
Respiration rate can be determined by the acoustic (RRa) or plethysmographic
waveform (RRp)

samples should be analyzed by laboratory instruments prior to clinical
decision making to completely understand the patient’s condition.
Caution
Variation in hemoglobin measurements may be profound and may be
affected by sample type, body positioning, as well as other physiological
conditions. As with most hemoglobin tests, Radical-7 test results should be
scrutinized in light of a specific patient’s condition. Any results exhibiting
inconsistency with the patient’s clinical status should be repeated and/or
supplemented with additional test data.
Parameter Related Safety Information, Warnings, and
Cautions
This section contains parameter related safety information.
Caution
If patient hypoxemia is indicated, blood samples should be analyzed by
laboratory devices to completely understand the patient’s condition.
Caution

Radical-7 Safety Information, Warnings, and Cautions
www.masimo.com 12 Masimo
Caution
Do not use In Vivo Adjustment if the monitor displays a Low SpHb SIQ
message.
Caution
If the Low Perfusion message is frequently displayed, find a better perfused
monitoring site. In the interim, assess the patient and, if indicated, verify
oxygenation status through other means.
Caution
Changing the SpHb Cal, the date and time of the system clock, or the trend
period clears the data in the trend memory.
Note: Interfering Substances: Dyes, or any substance containing dyes, that change usual
blood pigmentation may cause erroneous readings.
Note: Inaccurate SpCO and SpMet readings can be caused by:
Levels of methemoglobin approximately 1.5% or above
Intravascular dyes such as indocyanine green or methylene blue
Abnormal hemoglobin levels
Low arterial perfusion
Low arterial oxygen saturation levels including altitude induced hypoxemia
Elevated total bilirubin levels
Motion artifact
SpCO readings may not be provided if SpO2 readings are less than 90%
SpCO readings may not be provided if SpMet readings are greater than 2%
Note: SpO2, SpCO, SpMet, and SpHb are empirically calibrated in healthy adult volunteers
with normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb).
Note: The Radical-7 cannot measure elevated levels of COHb or MetHb.
Radical-7 Safety Information, Warnings, and Cautions
www.masimo.com 13 Masimo
Note: Inaccurate SpO2 readings may be caused by:
Elevated levels of COHb and MetHb
For increased COHb: COHb levels above normal tend to increase the level of
SpO2. The level of increase is approximately equal to the amount of COHb
that is present.
Note: High levels of COHb may occur with a seemingly normal SpO2. When
elevated levels of COHb are suspected, laboratory analysis (CO-Oximetry) of
a blood sample should be performed.
For increased MetHb: the SpO2 may be decreased by levels of MetHb of up to
approximately 10% to 15%. At higher levels of MetHb, the SpO2 may tend to read
in the low to mid 80s. When elevated levels of MetHb are suspected, laboratory
analysis (CO-Oximetry) of a blood sample should be performed.
Note: Inaccurate SpO2 readings may be caused by:
Intravascular dyes such as indocyanine green or methylene blue
Externally applied coloring and texture such as nail polish, acrylic nails, glitter,
etc.

Chapter 1: Technology Overview
The following chapter contains general descriptions about parameters, measurements, and
the technology used by Masimo products.
Signal Extraction Technology (SET)
Masimo Signal Extraction Technology's signal processing differs from that of conventional
pulse oximeters. Conventional pulse oximeters assume that arterial blood is the only blood
moving (pulsating) in the measurement site. During patient motion, however, the venous
blood also moves, causing conventional pulse oximeters to read low values, because they
cannot distinguish between the arterial and venous blood movement (sometimes referred to
as noise).
Masimo SET pulse oximetry utilizes parallel engines and adaptive digital filtering. Adaptive
filters are powerful because they are able to adapt to the varying physiologic signals and/or
noise and separate them by looking at the whole signal and breaking it down to its
fundamental components. The Masimo SET signal processing algorithm, Discrete Saturation
Transform® (DST®), in parallel with Fast Saturation Transform (FST®), reliably identifies
the noise, isolates it and, using adaptive filters, cancels it. It then reports the true arterial
oxygen saturation for display on the monitor.

General Description for Oxygen Saturation (SpO2)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the level of
arterial oxygen saturation in blood. The measurement is taken by placing a sensor on a
patient, usually on the fingertip for adults and the hand or foot for neonates.
The sensor is connected to the Pulse CO-Oximetry instrument with a patient cable. The
sensor collects signal data from the patient and sends it to the instrument. The instrument
displays the calculated data in three ways:
1. As a percent value for arterial oxygen saturation (SpO2)
2. As a pulse rate (PR)
3. As a plethysmographic waveform
Successful Monitoring for SpO2, PR, and PI
Stability of the SpO2 readings may be a good indicator of signal validity. Although stability
is a relative term, experience will provide a good feeling for changes that are artifactual or
physiological and the speed, timing, and behavior of each.
The stability of the readings over time is affected by the averaging mode being used. The
longer the averaging time, the more stable the readings tend to become. This is due to a
dampened response as the signal is averaged over a longer period of time than during
shorter averaging times. However, longer averaging times delay the response of the
oximeter and reduce the measured variations of SpO2 and pulse rate.

Functional Oxygen Saturation
The Radical-7 is calibrated to measure and display functional oxygen saturation (SpO2): the
amount of oxyhemoglobin expressed as a percentage of the hemoglobin that is available to
transport oxygen.
Note that carboxyhemoglobin is not capable of transporting oxygen, but is recognized as
oxygenated hemoglobin by conventional pulse oximetry.
General Description for Pulse Rate (BPM)
Pulse rate, measured in beats per minute (BPM) is based on the optical detection of
peripheral flow pulse.
General Description for Perfusion Index (PI)
The Perfusion Index (PI) is the ratio of the pulsatile blood flow to the non-pulsatile or static
blood in peripheral tissue. PI thus represents a noninvasive measure of peripheral perfusion
that can be continuously and noninvasively obtained from a pulse oximeter.
General Description for Pleth Variability Index (PVI)
The pleth variability index (PVI) is a measure of the dynamic changes in the perfusion index
(PI) that occur during the respiratory cycle. The calculation is accomplished by measuring
changes in PI over a time interval where one or more complete respiratory cycles have
occurred. PVI is displayed as a percentage (0-100%).
The utility of PVI is unknown at this time and requires further clinical studies. Technical
factors that may affect PVI include probe malposition and patient motion.

rainbow Pulse CO-Oximetry Technology
rainbow Pulse CO-Oximetry technology is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood), deoxyhemoglobin (non-oxygenated blood),
carboxyhemoglobin (blood with carbon monoxide content), methemoglobin
(blood with oxidized hemoglobin) and blood plasma constituents differ in their
absorption of visible and infrared light (using spectrophotometry).
2. The amount of arterial blood in tissue changes with your pulse
(photoplethysmography). Therefore, the amount of light absorbed by the varying
quantities of arterial blood changes as well.
Radical-7 Chapter 1: Technology Overview
www.masimo.com 27 Masimo
The Radical-7 uses a multi-wavelength sensor to distinguish between oxygenated blood,
deoxygenated blood, blood with carbon monoxide, oxidized blood and blood plasma.
The Radical-7 utilizes a sensor with various light-emitting diodes (LEDs) that pass light
through the site to a diode (detector). Signal data is obtained by passing various visible and
infrared lights (LEDs, 500 to 1400nm) through a capillary bed (for example, a fingertip, a
hand, a foot) and measuring changes in light absorption during the blood pulsatile cycle.
This information may be useful to clinicians. The maximum radiant power of the strongest
light is rated at ≤ 25 mW. The detector receives the light, converts it into an electronic
signal and sends it to the Radical-7 for calculation.
1. Light Emitting Diodes (LEDs)
(7 + wavelengths)
2. Detector
Once the Radical-7 receives the signal from the sensor, it utilizes proprietary algorithms to
calculate the patient’s functional oxygen saturation (SpO2 [%]), blood levels of
carboxyhemoglobin (SpCO [%]), methemoglobin (SpMet [%]), total hemoglobin
concentration (SpHb [g/dL]) and pulse rate (BPM). The SpCO, SpMet and SpHb
measurements rely on a multi-wavelength calibration equation to quantify the percentage
of carbon monoxide and methemoglobin and the concentration of total hemoglobin in
arterial blood. In an ambient temperature of 35º C the maximum skin surface temperature
has been measured at less than 106º F (41º C), verified by Masimo sensor skin temperature
test procedure.
Pulse CO-Oximetry vs. Drawn Whole Blood Measurements
When SpO2, SpCO, SpMet, and SpHb measurements obtained from the Radical-7
(noninvasive) are compared to drawn whole blood (invasive) measurements by blood gas
and/or laboratory CO-Oximetry methods, caution should be taken when evaluating and
interpreting the results.
The blood gas and/or laboratory CO-Oximetry measurements may differ from the SpO2,
SpCO, SpMet, SpHb, and SpOC measurements of the Radical-7. Any comparisons should be
simultaneous, meaning the measurement on the device should be noted at the exact time
that blood is drawn.
In the case of SpO2, different results are usually obtained from the arterial blood gas sample
if the calculated measurement is not appropriately corrected for the effects of variables that
shift the relationship between the partial pressure of oxygen (PO2) and saturation, such as:
pH,temperature, the partial pressure of carbon dioxide (PCO2), 2,3-DPG, and fetal
hemoglobin. In the case of SpCO, different results are also expected if concentration of
methemoglobin in the blood gas sample is abnormal (greater than 2% for methemoglobin
concentration).
High levels of bilirubin may cause erroneous SpO2, SpMet, SpCO, and SpHb readings. As
blood samples are usually taken over a period of 20 seconds (the time it takes to draw the
blood) a meaningful comparison can only be achieved if the oxygen saturation,
carboxyhemoglobin, and methemoglobin concentration of the patient are stable and not
changing over the period of time that the blood gas sample is taken. Subsequently, blood
gas and laboratory CO-Oximetry measurements of SpO2, SpCO, SpMet, SpHb, and SpOC may
Radical-7 Chapter 1: Technology Overview
www.masimo.com 28 Masimo
vary with the rapid administration of fluids and in procedures such as dialysis. Additionally,
drawn whole blood testing can be affected by sample handling methods and time elapsed
between blood draw and sample testing.
Measurements with Low Signal IQ should not be compared to laboratory measurements.
General Description for Total Hemoglobin (SpHb)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of total
hemoglobin (SpHb) in arterial blood. It relies on the same principles of pulse oximetry to
make its SpHb measurement. The measurement is taken by a sensor capable of measuring
SpHb, usually on the fingertip for adult and pediatric patients.
The sensor connects directly to the Pulse CO-Oximeter or with a patient cable. The sensor
collects signal data from the patient and sends it to the instrument. The instrument
displays the calculated data as measurement of total hemoglobin concentration.
Successful Monitoring for SpHb
A stable SpHb reading is associated with correct sensor placement, small physiological
changes during the measurement and acceptable levels of arterial perfusion at the
measurement site. Physiological changes at the measurement site are mainly caused by
fluctuations in the oxygen saturation, blood concentration and perfusion. See Safety
Information, Warnings, and Cautions on page 11 and Troubleshooting Measurements on
page 107.
General Description for Total Arterial Oxygen Content (CaO2)
Oxygen (O2) is carried in the blood in two forms, either dissolved in plasma or combined
with hemoglobin. The amount of oxygen in the arterial blood is termed the oxygen content
(CaO2) and is measured in units of ml O2/dL blood. One gram of hemoglobin (Hb) can carry
1.34 ml of oxygen, whereas 100 ml of blood plasma may carry approximately 0.3 ml of
oxygen*. The oxygen content is determined mathematically as:
CaO2 = 1.34 (ml O2/g Hb) x Hb (g/dL) x HbO2 + PaO2 (mm Hg) x (0.3 ml O2/100 mm Hg/dL)
Where HbO2 is the fractional arterial oxygen saturation and PaO2 is the partial pressure of
arterial oxygen.
For typical PaO2 values, the second part of the above equation (PaO2 [mm Hg] x [0.3 ml O2/
100 mm Hg/dL]) is approximately 0.3 ml/dL. Furthermore, for typical carboxyhemoglobin
and methemoglobin levels, the functional saturation (SpO2) as measured by a pulse
oximeter is given by:
SpO2 = 1.02 x HbO2

Edition. New York: Lippincott Williams & Wilkins, 1999.
Radical-7 Chapter 1: Technology Overview
www.masimo.com 29 Masimo
General Description for SpOC
The above approximations result in the following reduced equation for oxygen content via
the Pulse CO-Oximeter:
SpOC (ml/dL*) = 1.31 (ml O2/g Hb) x SpHb (g/dL) x SpO2 + 0.3 ml/dL
*When ml O2/g Hb is multiplied by g/dL of SpHb, the gram unit in the denominator of ml/g
cancels the gram unit in the numerator of g/dL resulting in ml/dL (ml of oxygen in one dL of
blood) as the unit of measure for SpOC. See Safety Information, Warnings, and Cautions on
page 11.
General Description for Carboxyhemoglobin (SpCO)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of
carboxyhemoglobin concentration (SpCO) in arterial blood. It relies on the same basic
principles of pulse oximetry (spectrophotometry) to make its SpCO measurement.
The measurement is obtained by placing a sensor on a patient, usually on the fingertip for
adults and the hand or foot for infants. The sensor connects either directly to the Pulse
CO-Oximetry instrument or through an instrument patient cable.
The sensor collects signal data from the patient and sends it to the instrument. The
instrument displays the calculated data as percentage value for the SpCO, which reflect
blood levels of carbon monoxide bound to hemoglobin.
Successful Monitoring for SpCO
A stable SpCO reading is associated with correct sensor placement, small physiological
changes during the measurement and acceptable levels of arterial perfusion in the patient’s
fingertip (measurement site). Physiological changes at the measurement site are mainly
caused by fluctuations in the oxygen saturation, blood concentration and perfusion.
General Description for Methemoglobin (SpMet)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of
methemoglobin concentration (SpMet) in arterial blood. It relies on the same basic
principles of pulse oximetry (spectrophotometry) to make its SpMet measurement.
The measurement is obtained by placing a sensor on a patient, usually on the fingertip for
adults and the hand or foot for infants. The sensor connects either directly to the Pulse
CO-Oximetry instrument or through a patient cable.
The sensor collects signal data from the patient and sends it to the instrument. The
instrument displays the calculated data as percentage value for the SpMet.
Radical-7 Chapter 1: Technology Overview
www.masimo.com 30 Masimo
Successful Monitoring for SpMet
A stable SpMet reading is associated with correct sensor placement, small physiological
changes during the measurement and acceptable levels of arterial perfusion in the patient’s
fingertip (measurement site).
Physiological changes at the measurement site are mainly caused by fluctuations in the
oxygen saturation, blood concentration and perfusion. See Safety Information, Warnings,
and Cautions on page 11.
SpCO, SpMet, and SpHb Measurements During Patient Motion
The Radical-7 displays measurements of SpCO, SpMet, and SpHb during patient motion.
However, because of the changes in the physiological parameters such as blood volume,
arterial-venous coupling, etc. that occur during patient motion, the accuracy of such
measurements may not be reliable during excessive motion. In this case, the measurement
value for SpCO, SpMet, or SpHb displays as dashes (---) and a message (Low SpCO SIQ, Low
SpMet SIQ, or Low SpHb SIQ) displays to alert the clinician that the instrument does not
have confidence in the value due to poor signal quality caused by excessive motion or other
signal interference.
rainbow Acoustic Monitoring (RAM) Technology
rainbow Acoustic Monitoring (RAM) continuously measures a patient’s respiration rate
based on airflow sounds generated in the upper airway. The Acoustic Sensor translates
airflow sounds generated in the upper airway to an electrical signal that can be processed to
produce a respiration rate, measured as breaths per minute.
Respiratory sounds include sounds related to respiration such as breath sounds (during
inspiration and expiration), adventitious sounds, cough sounds, snoring sounds, sneezing
sounds, and sounds from the respiratory muscles [1].
These respiratory sounds often have different characteristics depending on the location of
recording [2] and they originate in the large airways where air velocity and air turbulence
induce vibration in the airway wall. These vibrations are transmitted, for example, through
the lung tissue, thoracic wall and trachea to the surface where they may be heard with the
aid of a stethoscope, a microphone or more sophisticated devices.
rainbow Acoustic Monitoring Architecture
The following figure illustrates how a respiratory sound produced by a patient can be turned
into a numerical measurement that corresponds to a respiratory parameter.
Radical-7 Chapter 1: Technology Overview
www.masimo.com 31 Masimo
Patient
The generation of respiratory sounds is primarily related to turbulent respiratory airflow in
upper airways. Sound pressure waves within the airway gas and airway wall motion
contribute to the vibrations that reach the body surface and are recorded as respiratory
sounds.
Although the spectral shape of respiratory sounds varies widely from person to person, it is
often reproducible within the same person, likely reflecting the strong influence of
individual airway anatomy [2-6].
Sensor
The sensor captures respiratory sounds (and other biological sounds) much like a
microphone does. When subjected to a mechanical strain, (e.g., surface vibrations generated
during breathing), the sensor becomes electrically polarized.
The degree of polarization is proportional to the applied strain. The output of the sensor is
an electric signal that includes a sound signal that is modulated by inspiratory and
expiratory phases of the respiratory cycle.
Acquisition System
The acquisition system converts the electric signal provided by the sensor into a digital
signal. This format allows the signal to be processed by a computing device.
Radical-7 Chapter 1: Technology Overview
www.masimo.com 32 Masimo
Signal Processing
The digital signal produced by the acquisition system is converted into a measurement that
corresponds to the respiratory parameter of interest. As shown in the previous figure, this
can be performed by, for example, determining the digital signal envelope or outline which
in turn may be utilized to determine the respiratory rate. In this way, a real-time, continuous
breath rate parameter can be obtained and displayed on a monitor which, in many cases,
may be real-time and continuous.
The respiratory cycle envelope signal processing principle is similar to methods that sample
airway gasses and subsequently determine a respiratory rate.

connection, tighten the cable connector screws.
3. Connect the other end of the SatShare cable to one of the following:
Sensor connector of the multi-parameter monitor cable
Directly to the multi-parameter monitor
4. Verify that the Radical-7 recognizes the SatShare cable. If functional, the name of
the SatShare cable displays on the Radical-7 screen.
5. As appropriate, configure alarm limits on the multi-parameter monitor.
6. Set the averaging time for the multi-parameter monitor to its lowest setting (or
fastest response). The ideal waveform for the Radical-7 requires additional
averaging by the monitor. If the averaging time of the multi-parameter monitor
is not changed, the time to display physiological changes in saturation on the
monitor is increased with SatShare. However, the delay can be minimized by
reducing the averaging time on the multi-parameter monitor.
7. While in the SatShare mode, if there are any significant discrepancies between
the readings from Radical-7 and those on the monitor displaying the values
obtained from SatShare, the values reported by the Radical-7 are to be
considered the correct values.
8. It is possible to use the Radical-7 with SatShare while the Radical-7 is not
connected to AC power. However, in this configuration, battery run time is
reduced. See Battery Operation and Maintenance on page 127.
9. On the Radical-7, turn on the Satshare Numbers option. See Device Output on
page 79.
10. If displaying the simulated waveform is not desirable, it is recommended to turn
off the plethysmographic waveform display of the multi-parameter patient
monitor. See Serial Interface Specifications on page 118.

Overview of Sensitivity Modes
Three sensitivity levels enable a clinician to tailor the response of the Radical-7 to the needs
of the particular patient situation. Access the menu by tapping on the indicator in the upper
left corner of the Display View.
The sensitivity levels are as follows:
Normal Sensitivity
This is the recommended mode for patients that are experiencing some
compromise in blood flow or perfusion. It is advisable for care areas where
patients are observed frequently, such as an intensive care unit (ICU).
Adaptive Probe Off Detection (APOD) Sensitivity
This is the recommended monitoring mode where there is a high probability of
the sensor becoming detached. It is also the suggested mode for care areas where
patients are not visually monitored continuously. This mode delivers enhanced
protection against erroneous pulse rate and arterial oxygen saturation readings
when a sensor becomes inadvertently detached from a patient due to excessive
movement.
Maximum Sensitivity (MAX)
This mode is recommended for patients with low perfusion or when the low
perfusion message is displayed on the screen in APOD or normal sensitivity
mode. This mode is not recommended for care areas where patients are not
monitored visually, such as general wards. It is designed to interpret and display
data at the measuring site when the signal may be weak due to decreased
perfusion. When a sensor becomes detached from a patient, it will have
compromised protection against erroneous pulse rate and arterial saturation
readings.
Toggle between the sensitivity modes by pressing the indication on the top left of the
Display View. The sensitivity mode also can be changed in the Profile menu which is
accessible from the Main Menu.
Note that the device will revert to APOD mode after a power cycle.

Overview of In Vivo Adjustment
The In Vivo Adjustment feature lets clinicians manually adjust one or more clinical
parameters to match that of a corresponding laboratory reference for continuous trending.
To remind clinicians that the feature is active, an offset value displays alongside the
adjusted parameter value.
When the In Vivo Adjustment is set to Yes, the feature is active (turned on) and a positive or
a negative offset value appears, as shown in the following illustration.
In Vivo offset is set to zero for any of the following:
Cable or sensor disconnect from instrument.
Sensor goes off patient causing a sensor initialization to occur.
8 hours has elapsed since the In Vivo value was activated.
The user turns off In Vivo.
Offset value
Offset value appears and indicates that In Vivo Adjustment is active. A positive value means
that the value is increased (according to a laboratory reference value as entered by a
clinician) and a negative value means the value is decreased (according to a laboratory
reference value as entered by a clinician).
In the example below, the SpO2 value is offset (highlighted) by -1.0 and SpHb is offset by
+0.4.
The In Vivo Adjustment feature can be set to Yes or No. the factory default setting is No. If
set to Yes, the parameter value is adjusted and an offset value appears. The offset value is
set by the user.
The feature applies to any of the following parameters:

Overview of RRp
Respiration rate can be determined by the plethysmographic waveform (RRp) using a SpO2
sensor. Respiration rate monitoring, derived from the plethysmographic waveform,
measures a patient's respiratory rate based on amplitude changes that correspond to the
respiratory cycle.
Inaccurate measurements may be caused by:
Low arterial perfusion
Motion artifact
Low arterial oxygen saturation
Excessive ambient or environmental noise
Improper sensor placement
The device can display respiration rate derived from the plethysmographic waveform under

A third way, from the Main Menu screen, is by tapping the Profiles icon.
The Radical-7 stores three types of Profiles:
Custom (Default)
Any changes to Alarm settings are retained after a power cycle.
Adult
Any changes to Alarm settings are reset to pre-defined settings. The Adult profile
is the default profile after a power cycle.
Neonatal
Any changes to Alarm settings are reset to pre-defined Neonatal defaults after a
power cycle.
After Custom values are changed by the user, the Radical-7 retains these values after a
power cycle. The Adult profile and the Neonatal profile can be changed to meet specific
hospital or instrument requirements. If the Alarm settings are changed by the user, then
these settings return to the instrument default values after it is powered down. A user can
also load configurations to the device, which can be enabled by using the Profile button.

Adaptive Threshold Alarm (ATA) Feature
The Adaptive Threshold Alarm (ATA) feature is an optional feature that provides continuous
SpO2 surveillance while allowing the clinician a useful tool to help reduce the frequency of
audible alarms.
ATA establishes the alarm limit threshold based upon the patient-specific baseline value of
the SpO2 parameter which is determined from the recent history of SpO2 values. An
Adaptive Threshold Limit is continuously determined for the patient and SpO2 values
outside the Adaptive Threshold Limit trigger an audible alarm. The Adaptive Threshold
Limit is bound by the standard SpO2 low alarm limit and the Rapid Desat low alarm limit.
SpO2 values that exceed the Rapid Desat limit, whether it occurs rapidly or not, will activate
an audible alarm.
Prior to activating ATA, please review and select the appropriate standard low alarm limit
and other alarm settings. Once ATA is selected, the Rapid Desat Alarm protection is always
active. If the ATA low alarm limit is violated, ATA generates an audible alarm.
It is important to note that once activated, ATA has the following automatic safety features:
Reminder Tones
If an SpO2 value from a patient drops below the standard low alarm limit set by the user, a
visual alert will display and a reminder tone will repeat every 15 minutes as long as the
condition persists. If the SpO2 value drops below the ATA low alarm limit, an audible alarm
will be activated.
Rapid Desat Alarm Protection
The Rapid Desat feature is always active when ATA is turned on. This means that deep
desaturations (5% or 10%) from the standard SpO2 low alarm limit immediately generate an
audible alarm. When used with ATA, it also serves as absolute low alarm limit protection.
SpO2 values exceeding the Rapid Desat low alarm limit, whether rapid or not, will activate
an audible alarm. You can change the Rapid Desat default setting from 5% to 10%. ATA does
not allow a Rapid Desat default setting of 0%.
When ATA is turned Off, the instrument uses the standard alarm limits and standard alarm
delays.

3D Alarms
3D Alarms include the Desat Index Alarm and the PI Delta Alarm.
Overview of Desat Index Alarm on page 98.
Overview of Perfusion Index (PI) Delta Alarm on page 99.
Overview of Desat Index Alarm
The Desat Index Alarm is a user-selectable feature which allows a clinician to request an
audible and visual alarm if a patient experiences a specified number of desaturations over a
specific period of time.
Traditional high and low SpO2 alarm limits alert clinicians to saturation levels that exceed
user selected thresholds, and these thresholds are typically established at a considerable
change from the patients’ baseline saturation level. However, in select patient populations,
substantial desaturation events that exceed a typical low alarm limit threshold may be
preceded by a cycle of transient desaturations over a limited timeframe, and the ability to
alert clinicians to a cycle of these smaller desaturations may provide an earlier indication of
a potential significant decline in the patient’s status and the need for more focused
monitoring and/or a change in treatment.
To address patient populations at risk for cyclic, moderate desaturations, the option
includes a user-selectable Desat Index Alarm which allows the clinician to request an
audible and visual alarm in the event the patient experiences a specified number of
desaturations beyond a defined level from the patient’s baseline saturation over a specific
window of time, with each of these variables selectable by the user within established
ranges as noted in Desat Index Settings on page 98.

Overview of Perfusion Index (PI) Delta Alarm
The PI Delta Alarm is a user-selectable feature which allows a clinician to request an audible
and visual alarm if perfusion at the monitored site decreases by a specified level (delta) over
a specific period of time.
Perfusion Index gives an indication of the level of perfusion at the monitored site. The
Radical-7 measures perfusion at the SpO2 site by comparing the pulsatile signal to the
non-pulsatile signal, and expressing that ratio as a percentage. PI has been clinically proven
to be useful as a predictor of the level of illness in neonates and adults and that PI may
change dramatically in response to sympathetic changes caused by inhalational agents and
pain stimulation*. If PI decreases over time, there may be underlying physiological reasons
that may need to be addressed.
The PI Delta provides an audible and visual alert to important changes in perfusion
compared to the patient’s baseline PI rate. The baseline is set by the Radical-7 once the user
has enabled the alarm. The baseline is 30 seconds of currently averaged PI. The feature
includes a user-selectable PI Delta Alarm. This allows the clinician to request an audible and
visual alarm if perfusion at the monitored site decreases by a specified level (delta) over a
specified window of time. Three of the variables are selectable by the user within
established ranges as noted in PI Delta Settings on page 99.

Chapter 7: Troubleshooting
The following chapter contains information about troubleshooting the Radical-7 system.
Troubleshooting Measurements
See Parameter Related Safety Information, Warnings, and Cautions on page 11.
Signal Indication and Quality Indicator (SIQ)
The Radical-7 Pulse CO-Oximeter display provides a visual indicator of the plethysmogram
signal quality and an alert when the displayed SpO2 values are not based on adequate
signal quality. The signal quality indicator displayed on the Radical-7 Pulse CO-Oximeter is
called the SpO2 SIQ. The SpO2 SIQ can be used to identify the occurrence of a patient’s
pulse and the associated signal quality of the measurement.
With motion, the plethysmographic waveform is often distorted and may be obscured by
artifact. The SpO2 SIQ, shown as a vertical line, coincides with the peak of an arterial
pulsation. Even with a plethysmographic waveform obscured by artifact, the Radical-7 Pulse
CO-Oximeter locates the arterial pulsation. The pulse tone (when enabled) coincides with
the vertical line of the SpO2 SIQ.
The height of the vertical line of the SpO2 SIQ indicates the quality of the measured signal.
A high vertical bar indicates that the SpO2 measurement is based on a good quality signal.
A small vertical bar indicates that the SpO2 measurement is based on data with low signal
quality. When the signal quality is very low the accuracy of the SpO2 measurement may be
compromised. See About the Status Bar on page 49.
When parameters are dimly lit, proceed with caution and do the following:
Assess the patient.
Check the sensor and ensure proper sensor application. The sensor must be well
secured to the site for the Radical-7 Pulse CO-Oximeter to maintain accurate
readings. Misalignment of the sensor’s emitter and detector can result in smaller
signals and cause erroneous readings.
Determine if an extreme change in the patient’s physiology and blood flow at the
monitoring site occurred, (e.g. an inflated blood pressure cuff, a squeezing
motion, sampling of an arterial blood specimen from the hand containing the
pulse oximetry sensor, severe hypotension, peripheral vasoconstriction in
response to hypothermia, medications, or an episode of Raynaud’s syndrome.)
With neonates or infants, check that the peripheral blood flow to the sensor site
is not interrupted. Interruption, for example, may occur while lifting or crossing
their legs during a diaper change.
After performing the above, if the parameter remains dimly lit frequently or
continuously, obtaining an arterial blood specimen for CO-Oximetry analysis may
be considered to verify the oxygen saturation value.
See Parameter Related Safety Information, Warnings, and Cautions on page 11.
Radical-7 Chapter 7: Troubleshooting
www.masimo.com 108 Masimo
Dimly Lit Parameters
When the signal quality is very low, the accuracy of measurements may be compromised, the
parameter may be dimly lit, and the parameter may display dashes instead of a numeric
value.
Low Perfusion
It has been suggested that at extremely low perfusion levels, pulse oximeters can measure
peripheral saturation, which may differ from central arterial saturation This "localized
hypoxemia" may result from the metabolic demands of other tissues extracting oxygen
proximal to the monitoring site under conditions of sustained peripheral hypoperfusion.
This may occur even with a pulse rate that correlates with the ECG heart rate.
Low Signal Quality
Improper sensor type or application.
Next steps: Excessive motion relative to perfusion. Sensor is damaged or not functioning.
Check and see if blood flow to the site is restricted. Check the placement of the sensor.
Reapply sensor or move to a different site. See Appendix: Best Practices for Comparisons to
Reference Measurements on page 137.
SpO2 Values Do Not Correlate With Clinical Assessment or Arterial
Blood Gas Measurements
Low perfusion or sensor displacement.
Next steps: Check for error messages. See Chapter 6: Alarms and Messages on page 95.
Check placement of sensor or if it is too tight. Reapply sensor or select a new site. Set to
MAX sensitivity and confirm that the sensor is securely on the patient. See the directions for
use provided with your sensor.
Unexpected SpO2, SpCO, SpMet, or SpHb Reading
Low SIQ or PI values.

Analog Output
The Radical-7 Pulse CO-Oximeter can interface with various analog recording instruments or
strip chart recorders through its Analog Output connector located on the back of the
Docking Station. The output signals vary from approximately 0 to 1 volt in a linear fashion.
The actual analog output voltage generated may not exactly range between 0.0V to 1.0V. A
variance of ± 40 mV is acceptable.
Calibration
For instrument calibration purposes, the analog output signals can be set to either 0 Volts
or 1 Volt. Calibrate your analog recording system to those levels before use.
Nurse Call
The Nurse Call feature is available when the Radical-7 is operating as a standalone. Nurse
Call is based on the relay closing or opening depending on alarm, Low Signal IQ events, or
both. For maximum flexibility, either normally open (pin 6) or normally closed (pin 7)
signals are available. Only qualified personnel should connect one of these two signals and
common (pin 12) to a hospital’s Nurse Call system. During an alarm condition or a Low
Signal IQ event, depending on the configuration, the normally open pin will be connected to
the common pin and the normally closed will be disconnected. The Nurse Call polarity can
be inverted to accommodate various Nurse Call station requirements.

[1] SpO2, SpCO, and SpMet accuracy was determined by testing on healthy adult volunteers in
the range 60% to 100% SpO2, 0% to 40% SpCO, and 0% to 15% SpMet against a laboratory
CO-Oximeter. SpO2 and SpMet accuracy was determined on 16 neonatal NICU patients
ranging in age from 7 days to 135 days old and weighting between 0.5 kgs and 4.25 kgs.
Seventy-nine (79) data samples were collected over a range of 70% to 100% SaO2 and 0.5%
to 2.5% HbMet with a resultant accuracy of 2.9% SpO2 and 0.9% SpMet. Contact Masimo for
testing specifications.

Chapter 9: Service and Maintenance
The following chapter contains information about cleaning, battery operation, performance
verification, service, repair, and warranty.
Cleaning
Under normal operation, no internal adjustment or recalibration is required. Safety tests
and internal adjustments should be done by qualified personnel only. Safety checks should
be performed at regular intervals or in accordance with local and governmental regulations.
Safety Information, Warnings, and Cautions on page 11.
The Radical-7 Pulse CO-Oximeter is a reusable instrument. The instrument is supplied and
used non-sterile.
To surface clean the Radical-7
The outer surface of the instrument can be cleaned with a soft cloth dampened
with a mild detergent and warm water solution.
Do not allow liquids to enter the interior of the instrument.
The outer surface of the instrument can also be wiped down using any of the
following solvents:
Cidex Plus (3.4% glutaraldehyde)
10% bleach solution
70% isopropyl alcohol solution
Using the recommended cleaning solutions on the touchscreen panel will not affect the
performance of the Handheld.
Battery Operation and Maintenance
The Radical-7 Handheld includes a lithium ion rechargeable battery. The Radical-7 Docking
Station may include the optional 6.5 amp-hour nickel metal hydride rechargeable battery.
Before using the Radical-7 as a Handheld or as a transport monitor, the Handheld
rechargeable battery and the optional Docking Station rechargeable battery must be fully
charged.
To charge the Handheld rechargeable battery and the Docking Station rechargeable
battery
1. Attach the Handheld to the Docking Station.
2. Connect the Docking Station to AC power.
3. Verify that the batteries are charging.
The Docking Station Battery Charging indicator momentarily flashes and
then remains illuminated while the batteries are actively charging.
If the internal battery temperature exceeds recommended operating
conditions for proper battery charging, the Handheld Battery Charging
Radical-7 Chapter 9: Service and Maintenance
www.masimo.com 128 Masimo
indicator continuously flashes. When the temperature returns to
recommended operating conditions, proper battery charging proceeds.
The Handheld battery requires approximately 4 hours for charging. The
Docking Station battery requires approximately 6 hours for charging.
When both the Handheld Battery Charging indicator and the Docking
Station Battery Charging indicator turn off, additional trickle charging may
occur to complete charging.
Memory effects of the battery may shorten run-time. When battery run time
is significantly reduced, it is advisable to completely discharge and fully
recharge the battery. Charging can occur while the Handheld is docked and
turned on, the most efficient charge times are achieved when the Handheld
is turned off.
During battery operation of the Radical-7, note that the following operating conditions affect
the estimated run time of the included rechargeable batteries:
Estimated Run Times of Battery Power
The following tables outline the estimated run times of the battery-powered Radical-7. The
time estimates are based on a Radical-7 with fully charged batteries. The time estimates are
also based on a Radical-7 with and without the back-light illuminated.
The Radical-7 is always configured to include the Handheld battery. It may optionally be
configured to include the Docking Station battery. Determine the configuration of your
system before referencing the following tables.
Run Time for Handheld Only
In this configuration, the Radical-7 is configured to only include the Handheld battery
(standard configuration). When running on battery power, it is advisable to operate only the
Handheld. On battery power, it is possible to operate the Standalone (Handheld attached to
the Docking Station with the Handheld battery providing power to the Docking Station).
However, the capacity of the Handheld battery pack is not sufficient to support this mode for
long periods of time.
For optimal battery run time, configure the device to automatically adjust the brightness.
See Brightness on page 77.

Best Practices Checklist for Continuous SpHb Comparisons
1. Ensure SpHb device is turned on. If applicable, connect to computer with
automatic data capture.
2. Sensor site selection:
Remove anything from patient's arm that can impede blood flow to the
sensor site, such as restrictive garments, accessories, purses, backpacks,
watches, jewelry, and blood pressure cuff.
Do not use sites with any of the following conditions:
An anatomically abnormal finger (e.g. damaged, clubbed, deviated,
etc.).
A finger or arm that has experienced previous surgical procedures.
A finger or arm that is currently receiving an IV infusion.
A finger or arm that is currently used for blood pressure cuff.
Site should be cleaned of debris and dry prior to testing.
Nail polish should be removed prior to testing.
Select the patient’s testing finger in the following priority.
Non-dominant ring or middle finger.
Dominant ring or middle finger.
3. Sensor selection:
For reusable sensors, measure the patient's finger size (diameter) at the
cuticle, using the sensor size gauge, to determine the correct sensor size.
When using ReSposable sensors, connect the reusable optical sensor
(ROS) to the disposable optical sensor (DOS) after DOS properly placed onto
finger.
4. Ensure proper sensor positioning:
Rest patient’s hand and arm with sensor on a horizontal surface securely
to limit the movement of the patient.
Examine the finger while placed in the sensors to ensure the emitter and
detector are directly aligned on top of each other and there is no gap
between the sensor and fingertip.
Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements
www.masimo.com 138 Masimo
Align upper and lower red lines.
If using a reusable sensor, make sure finger tip is inserted all the way and
touching the finger stop inside the sensor (allowing long finger nails to
extend beyond the finger stop).
Ensure cable runs flat over the top of the hand directly in the middle of
the finger with no kinks or twists so the cable does not pull on the sensor.
Cover sensor with Masimo-provided shielding to avoid light interference.
Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements
www.masimo.com 139 Masimo
Secure sensor cable to patient’s arm with tape.
Instruct subjects to remain still without any sensor movement.
Connect sensor cable to device without pulling on sensor.
Wait until SpHb measurement is stable (one minute) before recording
SpHb values.
Note any Low SIQ message that displays during measurement.
5. Blood sampling and laboratory analysis:
Record site of blood draw.
Document exact time blood withdrawn from patient.
When taking blood sample from arterial line, remove adequate dead
space to ensure blood sample is not diluted with solution to keep arterial
line open. When IV line set-up includes stopcocks, ensure that no fluid is
infused through the line from which you are taking the blood. Draw blood
directly into the vacutainer, if possible.
Mix blood carefully after filling the vacutainer by rotating it gently at
least 10 times. (A rotation is one turn of the tube upside down and then
right side up.)
All blood samples must be analyzed on the same calibrated laboratory
hematology analyzer (Coulter, Sysmex, or equivalent) to avoid variation
induced by the use of multiple laboratory devices.

Best Practices Checklist for Acoustic Respiration Rate
Comparisons
Acoustic Sensor placement
The Acoustic sensor has a small black arrow on the front (see figure below), when placing
the sensor the black arrow should point forward to the anterior of subject’s body.
Ensure placement site is hair-free, clean of debris, and dry prior to sensor placement. Use
an alcohol swab to clean the neck area, if needed.
The preferred sensor placement site is either in quadrant 3 or 4 (center of sensor), see
figure below to either side of the larynx, avoid center of the neck. The most critical item is to
place the sensor at the site where it can receive the strongest breathing signal. To locate
this, place two fingers on the neck while the subject makes a continuous Ahhh sound and
choose the location that has the most vibration.
For pediatric subjects that have limited neck space, the sensor may be placed on the
right side of chest, underneath clavicle. The sensor should not be touching the clavicle.
Place sensor tape on skin. Gently press on sensor tape from center outward so adhesive
forms a good contact with patient's skin. Ensure there are no skin folds or air gaps under
sensor pad.
Remove the release liner from the anchor pad and place the anchor pad on patient’s side
of the neck; route the sensor cable in front of patient. Do not place anchor pad on clothing.
Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements
www.masimo.com 143 Masimo
Pulse-Oximeter Sensor Placement
Place finger sensor on middle or ring finger of hand opposite the blood pressure cuff.
For reusable sensors, make sure the fingertip just touches the rubber stopper at the end
of the sensor without going over it.
Ensure sensor is right side up with the cable running in line with finger, not at an angle
on dorsal (back side) of hand.
Monitoring
Ensure RRa device is turned on and connected to computer with automatic data capture.
Connect sensor to cable.
If RRa values are not displayed after 2 minutes or if the RRa value has dropped out, check
the following:
Confirm appropriate sensor placement, orientation and site selections.
Confirm that optical pulse-oximeter sensor is placed properly on the
patient's finger.
Confirm that all cables are plugged in at each of the various connection
points and hubs.
Auscultate with stethoscope to listen for air sounds on the side opposite
sensor. If breath sounds are present, remove sensor and replace with new
sensor on opposite side of neck.
Change the sensor out if RRa value continues to not display.
Verify that there is not excessive hair or a gap between the sensor and
the neck and that it is placed.
Simultaneously record the RRa and respiratory rates and from other methods. If
comparing RRa to capnography respiration rate, a mask is recommended. Sidestream
methods with a nasal cannula are not recommended because of dilution effect in the
supplemental flow of gasses, inability to measure both nasal and oral airflow, and nasal
cannula mispositioning. When recording values, confirm that there are no SIQ messages
displayed on the device.
Suggested directions to record manual respiration rate are as follows:
Use stethoscope to listen for breath sounds, count each breath cycle as
one breathe, count for 60 seconds.
Alternate method to stethoscope, count the number of chest
rises/inhalations during a 60 second period. Record manual respiration rate
to compare with RRa.
Adjust respiratory pause settings as necessary, default is 30 seconds (options are: 15, 20,
25, 30, 35, or 40 seconds).
Document patient events and time of event (based on computer clock). Include events
that may affect performance, these include:
Patient talking, picking at the sensor or nasal cannula, excessive
movement, ambient noise present, fans or air blowing at sensor
Inaccurate measurements may be caused by:
Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements

Excessive ambient or environmental noise (patient speaking, room
noise)
Improper sensor placement
Cable disconnection
