PRECAUTIONS

NOTE

This Operations Manual will describe both the MagnitudeTM 3150M and Omni-TrakTM 3150 MRI Monitors in detail. For simplicity the manual will refer to both these systems by the name “3150(M) MRI Monitor” except in the cases where a feature applies only to one of the two systems, in which case the specific 3150(M) MRI system will be referenced.

General

Federal law in the USA or Canada restricts this device to sale by, or on , the order of a physician.

The 3150(M) MRI Patient Monitoring System is comprised of the 3150(M) MRI Monitor and a Remote Monitor (Millennia® 3155MVS or 3155A). Always operate the 3150(M) MRI Monitor with its designated remote monitor.

The accuracy of the measurements can be affected by the position of the patient, the patient’s physiological condition, and other factors. Always consult a physician for interpretation of measurements made by this monitor.

To avoid remote monitor fall, secure monitor on the shelf or bracket prior to use.

An explosion hazard exists if this monitor is used in the presence of flammable anesthetics.

The operator should read and thoroughly understand this manual and the associated remote monitor manual (Invivo Research, Inc. Part Number 9545) completely before attempting to operate the 3150(M) MRI Monitor.

If any system failure occurs (e.g. an unexplained continuous audible alarm) remove the monitor from use, and refer it to qualified service personnel.

When the message “SOUND OFF”is displayed on the 3150(M) MRI Monitor (an “X” is displayed on the screen of the remote 3155 MVS or 3155A monitor), the audible alarm tone will not sound for any reason.

Perform operational checkout before each use. If monitor fails to function properly, refer to qualified service personnel.

For safe and accurate operation and MRI compatibility, use only recommended Invivo Research patient electrodes, cabling, lead wires, cuffs, hoses, sensors, tubing, etc. A listing of these can be found in the Accessory Listing within this manual, or by contacting Invivo Research directly.

For continued operation, always connect the monitor to AC Main Power through the AS153 AC Power Adapter when a Low Battery indication occurs. Failure to do this can lead to interruption of monitoring and/or damage to the monitor’s battery(s).

The system may not conform to all performance specifications if stored or used outside the environmental specifications identified in Appendix A in the rear of this manual.

Do not apply any unnecessary pressure to the screen area of the monitor. Severe pressure applied to this portion of the monitor could result in damage or failure of this screen.

All equipment not complying with IEC 601-1 should be placed outside the patient environment. Only connect IEC 601-1 compliant equipment to this monitor. To avoid potentially hazardous leakage currents, always check the summation of leakage currents when several items of equipment are interconnected.

For proper equipment maintenance, perform the service procedures at the recommended intervals as described in the monitor’s service manual.

Single use devices should never be reused.

PRECAUTIONS (Continued)

Electrical Safety

To avoid an electrical hazard, never immerse the unit in any fluid or attempt to clean it with liquid cleaning agents. Always disconnect monitor from AC Main Power before performing cleaning or maintenance.

Shock hazard exists if operated without chassis cover. Refer servicing to qualified service personnel only.

For continued protection against fire hazard, replace fuses with same type and rating only.

Avoid use of electrical power extension cords. Electrical power extension cords may create a safety hazard by compromising the grounding integrity of the monitor.

If the integrity of the earth conductor of the AC main power cable is in doubt, operate the monitor on internal battery power until proper earth connection is confirmed.

If monitor becomes accidentally wet during use, discontinue operation of the monitor until all affected components have been cleaned and permitted to dry completely. Contact your local Invivo Research, Inc. representative if additional information is required.

This monitor and its listed accessories maybe safely powered by the voltages 110-120/220-240 VAC having a frequency of 50 or 60 Hz.

MRI Use Precautions

Certain components of this device will be affected by the magnetic and radio frequency fields present in your MRI System. Confer with your MRI physicist and/or Radiology staff to identify the proper placement and use areas for the monitor and its accessories, as defined on the monitor or accessory labeling. Failure to properly place the monitor and its accessories in the Magnet Room will result in monitor failure, and possible patient or user injury. Always position the 3150(M) MRI Monitor at, or outside, the 5000 Gauss (0.5T) field line of the MRI system. A slight distortion of the MRI magnetic field homogeneity could result or possible damage to either the monitor's NIBP or EtCO2 pump could occur.

Always verify proper communication of the 3150(M) MRI Monitor with the Remote Monitor(s) prior to patient use.

MRI Magnet Room Placement. The 3150(M) MRI Monitor is designed to be used in conjunction with one or two remote monitor(s). The 3150(M) MRI Monitor is specially designed not to interfere with MRI operations and may be used inside the MRI Magnet Room in any location at or outside the 5000 Gauss (0.5T) Field Line of the MRI System. If brought closer than the 5000 Gauss Field Line, the NIBP monitor pump and EtCO2 pump may fail to operate.

The Remote Monitor(s) are also specifically designed not to interfere with MRI operations, and may be used in the Magnet Room at or outside the 1000 Gauss (0.1T) Field Line of the MRI System. If brought closer than the 1000 Gauss Field Line, monitor damage (failure to operate) may result.

Risk of RF current burn. Cables which become inadvertently looped during MRI act as conductive lines for RF induced currents. When lead wires or other cables form a conductive loop in contact with the patient's tissue, minor to severe burning can result.

v

PRECAUTIONS (Continued)

MRI Use Precautions (Continued)

Perform the following to minimize risk of RF current burn:

1.Place cables and lead wires neatly in straight alignment with no looping.

2.Keep the length of lead wires and patient cable within the bore to a minimum.

3.RF burn risk increases when multiple sensors/cables are in use. Such combinations are not recommended.

4.The high radio frequency (RF) power used in MRI scanning poses an ever-present risk of excessive heat at the monitoring sites and, therefore, the risk of RF current burn. Should power levels greater than S.A.R. of 4 w/kg peak (0.4 w/kg average) be used, the risk of patient burn greatly increases. As a result, monitoring of ECG or Respiration (derived from ECG leads) at power levels of greater than 4 w/kg peak (0.4 w/kg average) is not recommended for the general patient population. Such monitoring should only be attempted on conscious patients with good temperature reflex so they may warn the operator of excessive heat at the monitoring sites.

5.High RF Power may cause patient heating or burns. For scans with average S.A.R. > 1 w/kg, limit scan time to 5 minutes and pause at least 3 minutes between scans to allow ECG Cable to cool.

MRI Compatibility

The Quadtrode® MRI ECG Electrode Pad, and ECG Patient Lead Wires and Cable, are compatible with Magnetic Resonance Imaging (MRI) Systems within the following

guidelines:

!MRI systems with static magnetic field strengths up to 1.5 Tesla.

!Usable within the MRI system bore with Specific Absorption Ratios (S.A.R.'s) up to 4.0 w/kg (peak). Use with higher S.A.R.'s greatly increases the risk of patient burns.

!Non-Magnetic materials are used in the construction of these assemblies.

!If scanned directly across the plane of the ECG electrode element, a slight image distortion may be seen at the skin surface where the electrode element is positioned.

ECG

For best ECG and Heart Rate monitoring, always select the optimum lead configuration which has the least artifact and largest waveform(s) being detected for monitoring use.

Failure to respond to a Lead Fail alarm will cause a lapse in your patient’s monitoring. Always respond promptly to this and any other alarms.

MRI induced radiofrequency artifact can sometimes cause inaccurate heart rates. Inspect the ECG waveform during MRI scanning if spurious heart rates are observed.

vi

PRECAUTIONS (Continued)

ECG (Continued)

Bo (static) magnetic field artifact can present artificially-induced augmented T waves during ECG monitoring. Due to the effects of the magnetic field on the moving blood of the patient, follow the recommended ECG Electrode Placement to minimize this type of artifact.

An inoperative ECG monitor is indicated by absence of an ECG waveform and a simultaneous Lead Fail alarm.

Heart rate values may be adversely affected by cardiac arrhythmia, or by operation of electrical stimulators.

Pressures

For best invasive pressure monitoring, always select the appropriate waveform scale for the waveform being observed.

For invasive pressure monitoring, routinely inspect the catheter and/or pressure line for leaks after zeroing. Always follow the pressure transducer/catheter manufacturer’s use recommendations.

Never place the pressure transducer(s) within the MRI bore. Transducer failure or noisy MRI images can result.

Invasive blood pressure transducers are sensitive to vibrations that can occur during MRI scanning, which can lead to pressure reading inaccuracies. Always mount the invasive blood pressure transducer away from areas where vibration is likely to occur.

Always zero the pressure transducer(s) prior to patient use.

Non-physiological pulsatile invasive pressure waveforms (e.g., such as found during intra-aortic balloon pump use) can lead to inaccurate blood pressure readings. If questionable values are observed, re-check patient’s pressures by alternate means before administering medication or therapy.

Air that may be trapped within the pressure transducer or its associated tubing should be removed by flushing the system following established hospital or catheter lab procedures.

The fluid within the pressure transducer system is a conductive connection to the patient, and should not contact other conductive parts, including earth ground.

NIBP

Use only MRI Compatible NIBP Accessories (See MRI Accessory list in this Section).

When using the NIBP portion of this instrument to measure blood pressure, remember that the patient’s blood pressure readings are not continuous, but are updated each time a blood pressure measurement is taken. Set a shorter interval for more frequent updating of the patient’s blood pressure.

Do not attach the cuff to a limb being used for infusion. Cuff inflation can block infusion, possibly causing harm to the patient.

Frequent NIBP measurements can cause pooling of the blood in the limb (hemostasis), and peripheral tissue/nerve damage. Allow sufficient time for blood recirculation to prevent pooling of the blood in the limb.

Arrhythmic and/or erratic heart beats (or severe motion artifact, such as tremors or convulsions) can result in inaccurate readings and/or prolonged measurements. If questionable readings are obtained, re-check patient’s vital signs by alternate means before administering medication.

vii

PRECAUTIONS (Continued)

NIBP (Continued)

To prevent possible nerve damage to the limb, apply the NIBP cuff as recommended by current AHA guidelines for blood pressure monitoring.

To ensure accurate and reliable measurements, use only recommended patient cuffs/hoses. For best accuracy, use the appropriate cuff size for each patient as recommended by the current AHA guidelines for blood pressure monitoring.

Always tighten the cuff air hose connections snugly into place for proper operation.

Some reusable NIBP cuffs contain a medical-grade latex rubber. Patients sensitized to latex rubber can have an allergic reaction when exposed to this material. Avoid the use of cuffs which contain latex rubber on patients who are allergic to this material.

Routinely inspect the cuff and hose assemblies for proper attachment and orientation. Replace cuff and/or hose assemblies with cracks, holes, tears, cuts, etc. that could cause leaks in the system. If cuff and/or hose assemblies with damage which could result in leaks are used, prolonged and/or inaccurate patient readings could result.

To prevent skin abrasion, apply and remove cuff carefully. Keep Velcro® (hook and latch) retention areas away from the skin.

Always use recommended NIBP cuffs and hoses. Avoid compression or restriction of NIBP cuff hose.

SpO2

Use only MRI compatible fiberoptic SpO2 accessories (See MRI Accessory list in this Section).

Use only the Fiberoptic SpO2 sensors recommended by Invivo Research, Inc. A listing of these can be found in the Accessory List within this manual, or by contacting Invivo Research, Inc. directly.

The Fiberoptic SpO2 sensors are constructed of fiberoptic glass and should always be handled with care to prevent damage. Improper handling can reduce both the signal transmission quality and the SpO2 measurement sensitivity. Improper handling can also shorten the SpO2 sensor's useful life.

The numeric measurement values are updated every 1 second on the monitor display.

The pulse oximeter feature in this monitor is designed to display functional SpO2 values.

The pulse oximeter pulsatile waveform is not proportional to the pulse amplitude, but adjusts the waveform amplitude as needed for proper viewing.

All monitor alarms are categorized as medium priority, unless otherwise specified.

Avoid placement of the SpO2 probe on the same limb with an inflated blood pressure cuff. Cuff inflation could result in inaccurate readings and false alarm violations.

SpO2 monitoring requires the detection of valid pulses to correctly determine SpO2 and Heart Rate values. During conditions of gross artifact, or in the absence of valid pulses, the SpO2 /rate values may not be correct.

viii

PRECAUTIONS (Continued)

SpO2 (Continued)

The SpO2 monitoring portion of this monitor is intended to measure arterial hemoglobin oxygen saturation of functional hemoglobin (saturation of hemoglobin functionallyavailable for transporting oxygen in the arteries). Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin or methemoglobin, may affect the accuracy of the measurement. Also, Cardiogreen and other intravascular dyes may, depending on their concentration, affect the accuracy of the SpO2 measurement.

Always shield the SpO2 sensor from extraneous incident light sources. Such extraneous light can cause SpO2 reading or pulse detection errors.

Frequently inspect the SpO2 sensor site for possible pressure tissue necrosis during prolonged monitoring. Reposition the sensor at least every 4 hours. Special care should be exercised when tape is used to secure the sensor, as the stretch memory properties of most tapes can easily apply unintended pressure to the sensor site.

EtCO2

Always select the appropriate EtCO2 Tubing Set and gas sampling flow rate for the patient being monitored. Verify that the patient’s breathing efforts and timing coincide with the monitor’s waveform before completion of the patient set-up.

Frequently inspect the EtCO2 patient tubing for proper gas flow. Avoid kinking of the EtCO2 patient tubing that can result in leaking, reduction, or cut-off of the sample gas flow. Inaccurate gas measurements could result.

During EtCO2 monitoring, always use the appropriate water vapor evacuating tubing (i.e. Nafion® tubing) included in the patient circuit tubing kit to prevent inaccurate EtCO2 readings due to water vapor content of the patient's exhaled breath.

For proper operation, check the EtCO2 calibration during routine service. Routine calibration should not be required, but if the specified operation does not occur, have a qualified service person recheck the calibration. Proper re-calibration can only be performed during factory service.

EtCO2 patient tubing and its associated components are intended for single-patient use only. Avoid cleaning or disinfecting these items for reuse. Inaccurate gas measurements could result.

To prevent inaccurate or missed readings, keep the EtCO2 patient tubing clear of any moving mechanisms which may kink, cut or dislodge the patient tubing.

Avoid connecting the EtCO2 calibration gas canister to the monitor by any method other than with the designated calibration tubing. Connecting by any other method could invalidate the calibration, and/or damage the monitor.

The EtCO2/N2O measurements are automatically pressure compensated over an ambient pressure range of <645 to >795 mmHg.

The EtCO2/N2O measurement displays the sampled value within 1 second of when the gas was sampled.

The alarm tone volume exceeds 60 dBA at a distance of 1 meter when the alarm tone volume adjustment is set above selection number 4.

SECTION 1

INTRODUCTION

1.INTRODUCTION

The MagnitudeTM 3150M MRI Monitor is an evolution of the Omni-TrakTM 3150 MRI Monitor. Among other features, the MagnitudeT M 3150M MRI Monitor includes Digital Signal Processing (DSP) and an MRI View Mode. DSP provides improved ECG performance and reduction of MRI gradient artifact. The MRI View Mode provides adaptive ECG gradient filtering techniques for enhanced ECG display during MRI sequences. Both models of the 3150 MRI Monitor provide the operator with ECG, Respiration, SpO2, NIBP, EtCO2 and Invasive Pressures monitoring. Full control of patient monitoring is provided via the Invivo Research, Inc. Millennia® 3155A/3155MVS Monitor equipped with MRI shielding and set to Remote Communication Mode.

If operating a dual monitor system, the 3155MVS and 3155A patient monitors are interactive with one another through the 3150/3150M. As the “communication unit” the 3150/3150M acts to keep the commands that control patient parameter function synchronized throughout the MRI monitoring system. Should the 3150/3150M be turned off, it is possible to have patient parameters on the 3155A set to a particular configuration with the 3155MVS set to a different configuration; when the 3150/3150M is turned on the system will synchronize and all patient configurations will reflect the 3155A configuration.

This Operations Manual will describe both the MagnitudeTM 3150M and Omni-TrakTM 3150 MRI Monitors in detail. For simplicity the manual will refer to both these systems by the name “3150(M) MRI Monitor” except in the cases where a feature applies only to one of the two systems, in which case the specific 3150(M) MRI system will be referenced. Also, in the case of the Millennia® 3155MVS and 3155A Remote Monitors, they will be referred to (in this manual) only as “Remote Monitor(s).”

CAUTION

For continued patient safety and image integrity, use only those Invivo Research accessories

and equipment specifically designated for MRI.

1.1 Features. The 3150(M) MRI Monitor has been carefully engineered to take full advantage of the most

advanced technology.

!Integrated Control. Every feature of the 3150(M) MRI Monitor is synchronized with the Remote Monitor. This removes the need to manually check each monitor before beginning a scan.

!Software Control. The integration of the 3150(M) MRI Monitor and the Remote Monitor into a cohesive MRI Monitoring System is controlled by advanced software.

!Alarms and Trending. The 3150(M) MRI Monitor sends patient information to the Remote Monitor, where it can be analyzed and stored. Setting of Alarm High and Low Limits, Alarm Latching/Non-Latching, Alarm Tone and Volume, as well as all Trend Information Storage, is performed at the Remote Monitor.

!Complete Parameter Monitoring. This monitor will provide accurate and up-to-the-minute monitoring of a patient's ECG, NIBP, Invasive Blood Pressure, SpO2 and ETCO2.

!Digital Signal Processing (MagnitudeTM 3150M MRI Monitor only). Digital Signal Processing (DSP) of the ECG waveform is an innovative approach in removal of MRI gradient interference artifact from the ECG waveform.

1.3 Product Description. The 3150(M) MRI Monitor is a comprehensive MRI Patient Monitoring System that displays up to six (6) different patient parameters. The information that this monitor is capable of supplying to the physician may be used as an aid in the determination of a diagnosis concerning the condition of a patient. This monitor has been designed to perform to specification in MRI Magnet rooms where observation of a patient's parameters is necessary. This monitor is mounted on a four (4) wheeled base for stability during patient movement to and from the Magnet Room.

The 3150(M) MRI Patient Monitor includes the following Vital Sign Parameters:

!	ECG	!	Invasive Blood Pressure	!	Non-Invasive Blood Pressure
!	SpO2	!	ETCO2	!	Respiration

1.3.1System Parameters. The 3150(M) MRI Monitor System Parameters allow simultaneous processing and display of up to four parameter waveforms and associated numeric values from each different parameter. All the Patient Information is clearly displayed on a Flat Panel Display Screen.

1.3.2User Interface. The Control Panel, located to the right of the display screen, provides user interface with this monitor. From this Control Panel the operator may select the Lead and Size for ECG, Zero Invasive Blood Pressure 1 and 2, select the Patient Type for NIBP, set the NIBP automatic Cycle Time, Start/Stop an NIBP reading and turn monitor power On and Off.

1.3.3Versatility. With its complete offering of vital sign parameters, the 3150(M) MRI Monitor

may be configured to meet the MRI monitoring needs of a wide spectrum of patients from Neonate to Adult. Every available parameter may be easily accessed and adjusted from the MRI Control Room utilizing the Remote Monitor.
