• • 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 6.4.2.

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.

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 10-11 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%: MEASURED ARMS VALUES Range ARMS 90-100 % 1.30 % 80-90 % 1.78 % 70-80 % 2.80 % Range ARMS 70-100 % ± 2.1 % Overall Claimed Accuracy Value SpO2 Performance information of measured A(rms) accuracy shown in tabular form by range.

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.

USS Universal Serial Bus zeroing Ambient gas reference measurement used to establish zero concentration levels for CO2, N2O and Anesthetic Agents, as well as a calibration point for the oxygen measurements Warnings and Cautions To avoid water condensation inside the ISA module and the connecting tubings, ensure that the surrounding temperature of the ISA module and the connecting tubings does not fall below the ambient temperature of the Nomoline sampling line. E.1.2. 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. 10-15 E.2. Theory and design, 3886 Multi-Gas System E.2.1. Gas measurements and identification The measurement of CO2, N2O 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 CO2, N2O and a mixture of any two of the five anesthetic agents. JS 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 CO2 and N2O 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 10-16 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 10-17 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 MOisture) 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 CO2, N2O 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, 10-18 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" 10-19 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% O2 and 0% CO2), 3. For each gas that failed the Gas span check, perform step 4 to 7. Always perform the span calibration with the gases in order O2, N2O , DES and CO2 Example: Span calibration of O2 and CO2 only, start with O2 then CO2. 4. Supply the calibration gas and wait for at least 30 seconds. 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 O2 span calibration continues for about 40 s with a special zeroing during which the Servomex paramagnetic O2 sensor is sensitive to mechanical movements. 10-20 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 CO2, N20 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% O2 and 0% CO2) , ensure that the ISA is placed in a well-ventilated place. During Zeroing, if JSA's exhaust gas is returned to the patient circuit, the returned gas level will be different from the gas level at the sampling site 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 1h 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. 10-21 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 = EtCO2 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 CO2 measurement. This is known as spectral broadening. Nitrous oxide, N2O: ISA sidestream analyzers automatically compensates for spectral broadening caused by nitrous oxide. Below is the typical effect if using the default value (0 vol% N20) when measuring on gas mixtures with different N20 concentrations: N2O concentration in gas mix Effect on gas reading Displayed value if true concentration is 5.0 vol% CO2 0 vol% 30 vol% 60 vol% 82 vol% 0 % relative 5.17 % relative 10.34 % relative 14.14 % relative 5.0 vol% 5.3 vol% 5.5 vol% 5.7 vol% 10-22 Oxygen, O2: ISA OR+ sidestream units automatically compensates for spectral broadening caused by oxygen Below is the typical effect if using the default value (21 vol% 02) when measuring on gas mixtures with different O2 concentrations: O2 concentration in gas mix Effect on gas reading 21 vol% 0 % relative 5.0 vol% 50 vol% -2.76 % relative 4.9 vol% 70 vol% -4.67 % relative 4.8 vol% 95 vol% -7.05 % relative 4.7 vol% Displayed value if true concentration is 5.0 vol% CO2 E.3.

NOTE 2—These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people. 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 b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges. c 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.
