www.masimo.com 23 Masimo 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. Masimo rainbow SET Parallel Engines This figure is for conceptual purposes only.
Radical-7 Chapter 1: Technology Overview www.masimo.com 24 Masimo Masimo SET DST This figure is for conceptual purposes only. 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.
Radical-7 Chapter 1: Technology Overview www.masimo.com 25 Masimo 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.
Radical-7 Chapter 1: Technology Overview www.masimo.com 26 Masimo 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 *Martin, Laurence. All You Really Need to Know to Interpret Arterial Blood Gases, Second 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. [1] A.R.A. Sovijärvi, F. Dalmasso, J.

Radical-7 Chapter 3: Setup www.masimo.com 44 Masimo Setting Up and Using SatShare Parameter values from the Radical-7 can be displayed on a multi-parameter monitor through the SatShare feature. The SatShare feature provides an ideal, simulated plethysmographic waveform that corresponds to the parameter values determined the by Radical-7. This waveform may be used to display these values on multi-parameter monitors through the multi-parameter oximetry sensor or input connector. It is recommended that the Radical-7 be positioned near the multi-parameter monitor, with the Radical-7 screen displaying the plethysmographic waveform and the parameter values. Refer to the instructions for use provided with the multi-parameter monitor. See Device Related Safety Information, Warnings, and Cautions on page 15. To set up for use with SatShare interface 1. Select the SatShare cable that is appropriate for the multi-parameter monitor. For the latest list of available SatShare cables and validated instruments, see www.masimo.com. 2. Connect the labeled end of the SatShare cable to the SatShare Cable connector on the Docking Station. See Standalone Back Panel on page 39. For a secure 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.

Radical-7 Chapter 4: Operation www.masimo.com 50 Masimo 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.

Radical-7 Chapter 4: Operation www.masimo.com 60 Masimo 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.

Radical-7 Chapter 6: Alarms and Messages www.masimo.com 97 Masimo 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. About Alarms on page 95.

Radical-7 Chapter 6: Alarms and Messages www.masimo.com 98 Masimo 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. *De Felice C, Latini G, Vacca P, Kopotic RJ.

www.masimo.com 107 Masimo 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. Next steps: Reposition sensor to site with strong SIQ and PI. Average readings taken from three different sites to improve accuracy. Submit blood sample for laboratory CO-Oximetry test for comparison.  Inappropriate sensor size or sensor measurement location. Next steps:Verify proper sensor for patient size. Verify proper sensor site. See Appendix: Best Practices for Comparisons to Reference Measurements on page 137.
Radical-7 Chapter 7: Troubleshooting www.masimo.com 109 Masimo Unexpectedly High SpCO Reading Possible elevated methemoglobin level. Next steps: Submit blood sample for laboratory CO-Oximetry test. See Appendix: Best Practices for Comparisons to Reference Measurements on page 137. Difficulty Obtaining a Reading  Low battery/ not plugged into AC power supply. Next steps: Insert Handheld into Docking Station, verify Docking Station power cord plugged in and Docking Station power indicator light is illuminated.  Interference from line frequency induced noise. Next steps: Verify/set 50/60hz menu setting. See Localization on page 75.  Inappropriate sensor or sensor size. Next steps: Verify proper sensor and sensor size for the patient.  Excessive ambient or strobing light. Next steps: Shield the sensor from excessive or strobing light. Minimize or eliminate motion at the monitoring site. See Appendix: Best Practices for Comparisons to Reference Measurements on page 137. SpCO Reading Displays as Dashes  SpO2 value below 90% Next steps: Assess/address patient condition.  SpMet value greater than 2% Next steps: Laboratory analysis of a blood sample should be performed.  SpCO parameter has not yet stabilized during initial startup Next steps: Verify proper sensor and sensor size for the patient. Allow time for parameter reading to stabilize. See Appendix: Best Practices for Comparisons to Reference Measurements on page 137.

Radical-7 Appendix: Best Practices for Comparisons to Reference Measurements www.masimo.com 142 Masimo 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).
