• Do not place the NIBP cuff over a wound, as this can cause further injury.
• Do not place the NIBP cuff on the same or adjacent arm to a mastectomy, or where the
lymph nodes were removed, or if a shunt is on that arm. This can lead to bruising,
inaccurate readings, or negatively impact the drainage of fluids because of temporary
interference to blood flow.
! CAUTION
• Only use recommended MRI NIBP cuffs and tubing identified in section 9.2.
• In AUTO Mode, the monitor displays results of the last measurement until another
measurement starts. If a patient's condition changes during the time interval between
measurements, the monitor will not detect it.
• Excessive patient motion may cause inaccurate measurements. Minimize motion to
improve blood pressure measurements.
• Avoid crimping or undue bending, twisting, or entanglement of the NIBP hose.
6.4.1.1. Limitations
The following factors may affect the accuracy of measurement:
• Heart rate extremes of less than 40 bpm or greater than 240 bpm
• A regular arterial pressure pulse is hard to detect
• Cardiac arrhythmias
• Physical movement (patient or imposed)
• Rapid blood pressure changes
• Severe shock or hypothermia that reduces blood flow to the peripheries
• Obesity, where a thick layer of fat surrounding a limb dampens the oscillations coming
from the artery
• Edematous extremity

6.4.3. NIBP Patient Application
When positioning the patient, routine NIBP measurements (including for the condition
hypertension) require the patient to remain silent, still and relaxed, with legs uncrossed and
arms supported. Note that during MRI procedures, patients are typically lying down with their
legs uncrossed and arms supported as needed for the MRI scan. A five minute waiting period
is recommended before starting readings. Ensure that the cuff is at the level of the right atrium
of the heart.
1. Verify that the patient type is correct. Change it if necessary.
2. Ensure tubing is connected to the 3880 monitor
3. Select a correct sized cuff and then apply it as follows:
a. Determine the patient’s limb circumference.
b. Select an appropriate cuff by referring to the limb circumference marked on the
cuff. The width of the cuff should be 40% (50% for neonates) of the limb
circumference, or 2/3 of the upper arm’s length. The inflatable part of the cuff
should be long enough to encircle at least 50% to 80% of the limb.
c. Apply the cuff to an upper arm or leg of the patient and make sure the marking
on the cuff matches the artery location. Do not wrap the cuff too tightly around
the limb. It may cause discoloration, and ischemia of the extremities. Make sure
that the cuff edge falls within the marked range. If it does not, use a larger or
smaller cuff that will fit better.
4. Connect the cuff to the air tubing and make sure that the bladder inside the cover is not
folded and twisted
5. Press the START/STOP button to initiate a blood pressure reading. Hold TART/STOP
button down for three seconds to initiate a STAT burst of three successive NIBP
readings.
NOTE
• Automatic NIBP readings will not cycle when the monitor is in Standby
6.4.3.1. Setup Checklist

D. Masimo SETTM Technology
D.1. Masimo SET Principles of Operation
The Masimo SET® MS pulse oximeter is based on three principles:
1. Oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light
(spectrophotometry).
2. The volume of arterial blood in tissue and the light absorbed by the blood changes during
the pulse (plethysmography).
3. Arterio-venous shunting is highly variable and that fluctuating absorbance by venous blood
is a major component of noise during the pulse.
The Masimo SET® MS pulse oximeter as well as traditional pulse oximetry determines SpO2 by
passing red and infrared light into a capillary bed and measuring changes in light absorption
during the pulsatile cycle. Red and infrared light-emitting diodes (LEDs) in oximetry sensors
serve as the light sources, a photodiode serves as the photodetector.
Traditional pulse oximetry assumes that all pulsations in the light absorbance signal are caused
by oscillations in the arterial blood volume. This assumes that the blood flow in the region of the
sensor passes entirely through the capillary bed rather than through any arterio-venous shunts.
The traditional pulse oximeter calculates the ratio of pulsatile absorbance (AC) to the mean
absorbance (DC) at each of two wavelengths, 660 nm and 905 nm:
• S(660) = AC(660)/DC(660)
• S(905) = AC(905)/DC(905)
The oximeter then calculates the ratio of these two arterial pulse-added absorbance signals:
• R = S(660)/S(905)
This value of R is used to find the saturation SpO2 in a look-up table built into the oximeter’s
software. The values in the look-up table are based upon human blood studies against a
laboratory co-oximeter on healthy adult volunteers in induced hypoxia studies.
The Masimo SET® MS board pulse oximeter assumes that arterio-venous shunting is highly
variable and that fluctuating absorbance by venous blood is the major component of noise
during the pulse. MS board decomposes S(660) and S(905) into an arterial signal plus a noise
component and calculates the ratio of the arterial signals without the noise:
• S(660) = S1 + N1
• S(905) = S2 + N2
• R = S1/S2
Again, R is the ratio of two arterial pulse-added absorbance signals and its value is used to find
the saturation SpO2 in an empirically derived equation into the oximeter’s software. The values
in the empirically derived equation are based upon human blood studies against a laboratory
co-oximeter on healthy adult volunteers in induced hypoxia studies.
The above equations are combined and a noise reference (N’) is determined:
• N’ = S(660) - S(905) x R
If there is no noise N’ = 0: then S(660) = S(905) x R which is the same relationship for the
traditional pulse oximeter.
The equation for the noise reference is based on the value of R, the value being sought to
determine the SpO2. The MS board software sweeps through possible values of R that
correspond to SpO2 values between 1% and 100% and generates an N’ value for each of these
R-values. The S(660) and S(905) signals are processed with each possible N’ noise reference
10-12
through an adaptive correlation canceler (ACC) which yields an output power for each possible
value of R (i.e., each possible SpO2 from 1% to 100%). The result is a Discrete Saturation
Transform (DST™) plot of relative output power versus possibleSpO2 value as shown in the
following figure where R corresponds to SpO2 = 97%:

E. Internal CO2 Only, and Masimo Multi-Gas Systems Detail Operation
The 3880 MRI Patient monitoring system has two options for gas measurement. There being a
‘built in’ CO2/Respiration only option and an externally packaged Multi-Gas option with full
automatic anesthetic agent identification as well as ‘fast’ parametric O2, known as P/N 3886.
The ‘built in’ CO2 only option is housed within the 3880 monitor unit and operable to the full
magnetic limits of the 3880 monitor unit, 30,000 Gauss. Using the Parameter Setup menu, the
user can select CO2 only which will activate this internal CO2 unit and display CO2 waveform,
Et and Fi CO2 as well as respiration this internal unit measures.
Likewise, from the Parameters Setup menu the operator can select Agents which turns off the
internal CO2 only unit and causes the 3880 monitor unit to communicate with the external 3886
Multi-Gas unit. The 3880 now displays CO2 waveform, Et and Fi CO2, respiration, anesthetic
agents, N2O, and 02 from the 3886 unit. The core of the 3886 is the Masimo/Phasein ISA
sidestream OR+ Multi-Gas system which includes the Servomex Pm1116 Fast Oxygen
transducer. These devices have a long history of successful deployment in various non-MRI
monitors. The 3886 unit, provides magnetic and RF shielding allowing use in MR with magnetic
fields up to 600 Gauss, as such the 3886 is to be mounted on the MR gas machine or other
fixed position below 600 Gauss.

3886 Multi-Gas Unit
ISA OR+
The 3886 Multi-Gas Unit contains the Masimo ISA OR+ which is a low-flow sidestream
multigas analyzer designed to monitor respiratory concentrations of CO2, N 2O and gas
mixtures containing any two of the five anesthetic agents Halothane, Enflurane, lsoflurane ,
Sevoflurane and Desflurane in the OR and the ICU. Its low sampling flow and low agent
identification threshold makes the ISA AX+ a perfect choice for adult and pediatric
applications, as well as for the monitoring of infant patients with low tidal volumes and high
respiratory rates .
ISA OR+ sidestream analyzer offers the addition of oxygen measurement capabilities by
means of an integrated paramagnetic O2 sensor.
In the following information regarding the 3886 Multi-Gas Unit, the Masimo term “OR+” is
used interchangeably.

E.2.1.
Gas measurements and identification
The measurement of CO
2
, N
2
O and anesthetic agents is based on the fact that different
gases absorb infrared light at specific wavelengths. The analysis of respiratory gases by
the ISA gas analyzers are therefore performed by continuously measuring the infrared
light absorption in the gas flow through an infrared spectrometer. Oxygen, on the other
hand, does not absorb infrared light to the same extent as other breathing gases and is
therefore measured using alternative methods.
The gas analysis
The heart of the ISA gas analyzer is the multi-channel spectrometer which uses a
proprietary broadband infrared radiation source to transmit light through the gas sample.
Before reaching the gas sample, the light path is intersected by narrowband optical filters
that only allow light corresponding to selected wavelength peaks of the measured gases
to pass. At the other end of the light path, a sensor detects the portion of the light that is
not absorbed by the gas. The amplitude of the detector output is an inverse function of
the gas concentration.
Thus, at a concentration of zero, the amplitude is at its maximum.
If the gas sample is a mixture of several components that absorb light at the same
wavelength, such as a mixture of two anesthetic agents, the absorbed radiation will be
the sum of the absorption of the agents. To determine the concentration of each of the
individual gases, several filters have to be used. The ISA gas analyzers therefore uses
the SIGMA spectrometer, which contains up to nine different narrowband filters to
facilitate simultaneous measurement of CO
2
, N
2
O and a mixture of any two of the five
anesthetic agents.
Figure 4-1. Gas absorption spectra.
The selection of the optical filters within the spectrometer is crucial to the characteristics
and performance of the gas analyzers. The ISA spectrometer uses the strong absorption
peaks at and 4.5 µm for CO
2
and N
2
O measurements and five wavelengths in the 8 to
10 µm long wave infrared range (LWIR) for the anesthetic agent calculations. The LWIR
contains strong absorption peaks for the anesthetic agents and negligible interference
from other common respiratory gases, such as alcohol and acetone, which could degrade
10-17
measurement accuracy.
In addition to the measurement filters, two optical filters appropriately located within the 4
to 10 µm range are used as references.
E.2.2. Oxygen measurement, Paramagnetic
Oxygen does not absorb infrared light to the same extent as other breathing gases and is
therefore measured using alternative methods. The ISA OR+ analyzer is fitted with a
paramagnetic oxygen sensor.
Paramagnetic oxygen analysis
Paramagnetic oxygen analysis is based on measurements of the attractive force exerted
by a strong magnetic field applied to the oxygen molecules in a gas mixture. The
paramagnetic analyzer distinguishes oxygen from other gases as a function of their
magnetic susceptibility. Due to its paramagnetic nature, oxygen is attracted into the
magnetic field, while most other gases are not. On a scale, where oxygen is assigned the
value 100, most other gases have a magnetic susceptibility of close to zero.
The Servomex sensors
The oxygen sensor included in the 3886 Multi-Gas system as part of the ISA OR+ gas
analyzer is the Pm1116 paramagnetic oxygen sensor from Servomex. In these sensors, a
symmetrical non- uniform magnetic field is created. If oxygen is present, it will be attracted
into the strongest part of this field. Two nitrogen-filled glass spheres are mounted on a
rotating suspension within the magnetic field. Centrally on this suspension, a mirror is
mounted. A light beam projected on the_mirror is reflected onto a pair of photocells.
Oxygen attracted into the magnetic field will push the glass spheres from the strongest
part of the magnetic field, causing the suspension to rotate.
When this rotation is detected by the photocells, a signal is generated and passed to a
feedback system. The feedback system will pass a current around a wire mounted on the
suspension, causing a restoring torque that keeps the suspension in its original position.
The current flowing around the wire is measured. This current is directly proportional to
the oxygen concentration.
Figure 4-2. Oxygen measurement with Servomex paramagnetic oxygen sensors.
The most important benefits of the paramagnetic oxygen sensor are:
•
Fast rise time
•
High stability and accuracy
•
No chemicals to replace or renew
•
Low maintenance requirement
10-18
E.2.3. Sampling
A sidestream gas analyzer continuously removes a gas sample flow from the respiratory
circuit, for example a nasal cannula, a respiratory mask or the Y-piece of an intubated
patient. The gas sample is fed through a sampling line to the gas analyzer. The sampled
gas is usually warm and humid, and cools down in contact with the wall of the sampling
line. Water therefore condenses in form of droplets on the inner wall of the sampling line.
These droplets could potentially occlude the sampling line and interfere with the gas
measurement.
The Nomoline Family
To overcome the shortfalls of current gas sampling solutions, the Nomoline Family
sampling lines have been developed for the ISA sidestream gas analyzers.
Unlike traditional solutions that remove water vapor and collect water in a container, the
Nomoline Family sampling lines incorporates a unique water separation
(NO MO
isture)
section, which removes condensed water. The NOMO section also has a bacteria filter
which protects the gas analyzer from water intrusion and cross contamination.
Figure 4-3 . The NOMO section.
The Nomoline Family sampling lines are specially designed for 50 sml/min low sample
flow applications. The Nomoline Family sample lines have a very low dead space that
results in an ultra-fast rise time, making measurements of CO
2,
N
2
O
and anesthetic agents
possible even at high respiratory rates. ISA sidestream gas analyzers are therefore
suitable for adult, pediatric and infant patients.
The Nomoline Family sampling lines are available in a wide variety of versions for both
intubated and spontaneously breathing patients and in both disposable and ReSposable
configurations - intubated patients can for instance be monitored using the disposable
Nomoline Airway adapter Set or a combination of the multiple patient use Nomoline
Adapter and a disposable Nomoline Extension / T-adapter.
The Nomoline Airway Adapter Set with integrated airway adapter can be used with
intubated patients.
The Nomoline with a male Luer Lock type connector is compatible with any normal
configuration that uses a female Luer Lock connector. When connecting to a T-adapter,
10-19
be sure to use a Masimo T-adapter that samples the gas from the center of the T-adapter
(see below). See section
12
for ordering details.
Flow control
During normal operation, a sidestream gas analyzer is continuously fed with a small
sample gas flow. To pull the gas through the sampling line and maintain a steady flo w, a
high-precision flow control system is required. In !SA sidestream gas analyzers, the flow
control system consists of an integrated micro pump, a zero valve and a flow controller.
The pump is fitted with a low-power brushless motor incorporating three miniature ball
bearings to ensure trouble free operation without the need for regular maintenance. Its
balanced shaft design and integrated pneumatic filter virtually eliminates pressure and flow
variations.
System response
In any sidestream gas analyzer, there are three major time parameters characterizing the
system:
•
Total system response time
•
Delay time
•
Rise time
When designing a sidestream gas monitoring system, the physical characterist ics of
several components have to be considered. Parameters such as sampling line volume,
tubing material and the physical design of the sampling interfaces play decisive roles in
determining the responsiveness of the system.
Generally, the total system response time equals the delay time plus the rise time.
The rise time is defined as the time required for a step function change at the sampling
site to bring about a rise from 10% to 90% of the final gas concentration value. The total
numbers of gas fittings together with the physical design of the fittings are examples that
effects the rise time. Fast rise times are important when monitoring infants with high
breathing rates.
The delay time is defined as the time required for a step function change at the sampling
site to result in 10% of the final value. Parameters affecting the delay time are the sample
flow rate, tubing length and tubing inner diameter. In mainstream gas monitoring, where
no tubing exist, the delay time is virtually zero, whereas a sidestream system has a
sample delay time of a few seconds.
Leak test
1.
Connect a Nomoline Adapter and a Nomoline Extension sampling line or equivalent to
the ISA gas analyzer, with the analyzer connected to Masimo Gas Master.
2.
Tightly block the gas inlet of the Nomoline sampling line.
Check the field "Atm press - cuvette press [kPa]" in Masimo Gas Master - the
pressure value will start to rapidly increase, until the internal pump stops.
When the internal pump stops and while keeping the inlet blocked, quickly block the
exhaust port tightly. When blocked, the "Atm press - cuvette press [kPa]" in Masimo
Gas Master shall be >6 kPa.
3.
Stop the pump by sending parameter "Stop pump" under "Installation & maintenance"
10-20
in Masimo Gas Master.
4.
Wait about 1O seconds until the "Atm press - cuvette press [kPa]"value as shown by the
Masimo Gas Master is stable. Note the value.
5.
Wait additional 10 seconds.
6.
Check that the "Atm press - cuvette press [kPa]"value has not changed more than 3 kPa in
10 seconds.
7.
If the "Atm press - cuvette press [kPa}" value changes more than 3kPa in 10 seconds,
check tubing and fittings for leakage. If the problem persists, return the analyzer to Masimo
Sweden (see section 9).
Note:
In step 5, if the "Atm press - cuvette press [kPa]" is less than 6 kPa, repeat
steps 1 to 3 blocking the exhaust port quicker.
Gas span calibration
Only perform the gas span calibration if the gas span check fails repeatedly.
Before performing the gas span calibration, ensure that the SETO2 and SETN2O values are
set (if applicable for your gas analyzer model) correctly to match the corresponding calibration
gas.
Span calibration can be performed using gases within the ranges:
4.0% ≤ CO2 ≤ 11.0%
45% ≤ O 2 ≤ 100% - for ISA Multigas with Servomex only
30% ≤ N2O ≤ 100% - for ISA Multigas only
2.0% ≤ DES ≤ 12.0% - for ISA Multigas only
The accuracy of the individual components of the calibration gas mixture shall each have
an accuracy of at least +/-0.03 vol% or +/-(0.02 vol% +0.1% of reading), whichever is
greater.
Note
: DES shall be used for span calibration of all 5 agents (HAL, ENF, ISO, SEV, DES).
Note: Gas span calibration should be performed only for the gas components that failed
in the Gas span check.
1.
Warm up the ISA gas analyzer for at least 1 min
2.
Send "Pre span calibration zeroing" and make sure that the surrounding gas is normal air
(21%

4.

5.
Send the corresponding span calibration command.
6.
Wait until the gas span calibration is no longer in progress. The calibrationgas can be
turned off when "span calibration is in progress" no longer is set, but the
O

span
calibration continues for about 40 s with a special zeroing during which the Servomex
paramagnetic
O

sensor is sensitive to mechanical movements.
10-21
7.
Verify the gas readings
Notes:
If the calibration process fails, the flag SPAN_ERR is set, and will stay
active until the next successful calibration is passed.
As long as no sampling line is connected, an ISA gas analyzer stays in a low-power,
sleep mode. Once the sampling line is connected, the ISA gas analyzer switches to
measuring mode and starts delivering gas data.
E.2.4.
Zeroing ·
The infrared gas analyzer needs to establish a zero reference level for the CO
2,
N
2
0
and
anesthetic agent gas measurement. This zero calibration is here referred to as
"Zeroing".
ISA sidestream gas analyzers perform Zeroing automatically by switching the gas
sampling from the respiratory circuit to ambient air. The automatic Zeroing takes less
than 3 seconds for ISA CO2 gas analyzers and less than 10 seconds for ISA multigas
analyzers. If the ISA sidestream gas analyzer is fitted with an oxygen sensor, the
automatic Zeroing will also include room air calibration of the oxygen sensor. Since a
successful Zeroing requires the presence of ambient air (21% O
2
and 0% CO
2) ,
ensure
that the ISA is placed in a well-ventilated place.

ISA OR+ Multigas
analyzers normally perform Zeroing directly at startup (with or
without Nomoline attached), when a steady operating temperature is achieved and
thereafter
every
8 h from start up. A Zeroing is also performed when the operating mode
is changed from sleep mode to measurement mode.
Additional automatic Zeroing can however be performed if the system consider it
necessary.
E.2.5.
Flow reference zeroing
Addition to the Zeroing the ISA sidestream gas analyzer also perform an automatic flow
reference zeroing
1
h from startup and thereafter
every
96h. During a flow reference
zeroing the ISA sidestream gas analyzers switch from gas sampling from the respiratory
circuit to ambient air while the pump is switched off. Hence no flow will be drawn from the
reference inlet. During the automatic flow reference zeroing , which takes less than 8
seconds , the LEGI will be blinking with a green light.
10-22
E.2.6.
Gas data considerations
Gas measurement units
Effects of humidity
The partial pressure and the volume percentage of CO2 , N2O , O2 and anesthetic agents
depend on the amount of water vapor in the measured gas. The O2 measurement will be
calibrated to show 20.8 vol% at actual ambient temperature and humidity level, instead of
showing actual partial pressure. 20.8 vol% O2 corresponds to the actual O2 concentration in
room air with 0.7 vol% H20 concentration (at 1013 hPa this equals for example 25°C and
23% RH). The measurement of CO2, N2O, and anesthetic agents (e.g. all gases measured
by the IA-bench) will always show the actual partial pressure at the current humidity level.
In the alveoli of the patient, the breathing gas is saturated with water vapor at body
temperature (BTPS). When the breathing gas flows through the sampling line, the gas
temperature will adapt to ambient before reaching the gas analyzer. As the NOMO
section removes all condensed water, no water will reach the ISA gas analyzer. The
relative humidity of the sampled gas will be about 95%.
If
CO2
values at BTPS are required, the following equation can be used:
where :
EtCO2
= EtC
O2
value sent from ISA [vol %]
Pamb = Ambient pressure sent from ISA [kPa]
3.8 = Typical partial pressure of water vapor condensed between patient circuit and ISA [kPa)
EtC02(BTPS) = EtCO2 gas concentration at BTPS [vol%]
Spectral broadening
The presence of oxygen and nitrous oxide can cause some interference in the CO
2
measurement. This is known as spectral broadening.
Nitrous oxide, N2O:
ISA sidestream analyzers automatically compensates for spectral broadening caused by
nitrous oxide.

reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the 3880 System is used
exceeds the applicable RF compliance level above, the 3880 System should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the 3880 System.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined
using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE 1—At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2—The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to
13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
NOTE 3—An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the ISM frequency
bands
between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable
communications
equipment could cause interference if it is inadvertently brought into patient areas.
NOTE 4—These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
Recommended separation distances between the 3880 System components and local radio frequency devices, such as WiFi AP devices, for wireless
coexistence: Maintain a 2 meter ( 6’) separation.
