Precautions
General
Federal law in the USA or Canada restricts this device to sale by, or on the order of, a physician.
The Millennia®3155A/3155MVS Monitor supplied with your Omni-TrakTM 3150/MagnitudeTM
3150M monitor is factory set to communicate only with the specific monitor it came with.
The Omni-TrakTM 3150/MagnitudeTM 3150M MRI Patient Monitoring System is comprised
of the 3150(M) and a Millennia®3155A/3155MVS Remote Monitor. Always operate the Omni-
TrakTM 3150/MagnitudeTM 3150M MRI Patient 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 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 completely before attempting to
operate the Millennia®3155A/3155MVS 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 an “X” appears in the Alarm Bell symbol, 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, use only recommended Invivo Research patient cable, lead wires,
cuffs, hoses, sensors, tubing, etc. A listing of these can be found in the Accessory Listing within
the 3150(M) manual (Part Number 9538), 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.
Organic vapors (e.g. from cleaning agents) in sampling line or room air may alter anesthetic agent
readings.
Alcohol in patient's breath may modify the anesthetic agent readings.

vii
Precautions
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 DC 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.
If the integrity of the earth conductor of the AC mains power cable is in doubt, operate the
monitor on internal battery power until proper earth connection is confirmed.
Avoid use of electrical power extension cords. Electrical power cords may create a safety hazard
by compromising the grounding integrity of the monitor.
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 may be safely powered by the voltages 110-120/220-240 ~
having a frequency of 50 or 60 Hz.
Occupational Safety
Connect the sample gas outlet on the monitor's rear panel to scavenging system to prevent
pollution of room air.
Handle the Patient Sampling Line and its contents as you would any body fluid. Infectious hazard
may be present.
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
Millennia®3155A/3155MVS Monitor 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.
Always verify proper communication of the Omni-TrakTM 3150/MagnitudeTM 3150M MRI
Patient Monitor with the Millennia®3155A/3155MVS Monitor prior to patient use.
MRI Magnet Room Placement. The Omni-TrakTM 3150 MRI/MagnitudeTM 3150M MRI
Patient Monitor is designed to be used in conjunction with a remotely located Millennia®
3155A/3155MVS Monitor. The Omni-TrakTM 3150/MagnitudeTM 3150M MRI Patient
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.

viii
Precautions
ECG
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.
For other ECG related precautions, refer to the 3150(M) Monitor Operations Manual (IRI Part
Number 9538).
NIBP
Always use recommended NIBP cuffs and hoses. Avoid compression or restriction of NIBP cuff
hose.
For other NIBP related precautions, refer to the 3150(M) Monitor Operations Manual (IRI Part
Number 9538).
SpO2
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 volume, but adjusts the
waveform amplitude as needed for proper viewing.
All monitor alarms are categorized as medium priority, unless otherwise specified.
For other SpO2 related precautions, refer to the 3150(M) Monitor Operations Manual (IRI Part
Number 9538).
EtCO2
Always select the appropriate EtCO2 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.
The N2O measurements are automatically pressure compensated over an ambient pressure
minimum range from 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.
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.
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.
Respiration rate measurement errors could result during ventilation rates above 80 breaths per
minute.

ix
Precautions
Anesthetic Agents
Inadequate ventilation of the monitor may cause inaccurate readings or damage to electronic
components.
Ensure that the exhaust gas is not removed from the monitor under too strong suction. To prevent
suction, there must always be an opening to the room air. Strong suction may change the
operating pressure of the monitor and cause inaccurate readings or internal damage.
Inspect waste gas line for deterioration on a routine basis. Replace as needed.
Remove sampling line from patient airway whenever nebulized medications are being delivered.
Use only Invivo Research, Inc. sampling lines and accessories; other sampling lines may cause
inaccurate readings and malfunctions.
In Desflurane Gas Mixtures, the change in concentration of the other anesthetic may become
clinically significant before a gas mixture alarm is given.
Some Hydrocarbons (e.g. Acetone, Methane) may cause a mixed agent alarm to occur.
Replace the sampling line and filter between each patient use.
Routinely inspect the hose assemblies for proper attachment and orientation. Replace hose
assemblies with cracks, holes, tears, cuts, etc. that could cause leaks in the system. If hose
assemblies with damage which could result in leaks are used, prolonged and/or inaccurate patient
readings could result.
If questionable oxygen or anesthetic agent gas measurements are observed, recheck patient
connections, anesthesia gas machine and/or vaporizer before re-adjusting oxygen or anesthesia
delivery.
Always respond to patient tubing disconnect alarms immediately to prevent lapse in patient
monitoring.
Routinely verify the monitor’s internal barometric pressure reading with local conditions during
the initial start-up period.
Gas mixtures of Desflurane and Sevoflurane will not cause a multiple agent alarm. The optical
filters used to determine Desflurane and Sevoflurane are very similar, making it very difficult to
determine the presence of Desflurane and Sevoflurane at the same time. The identification could
be either Desflurane or Sevoflurane in concentration values (Fi and ET) greater than either of the
actual concentrations of Desflurane and Sevoflurane.
During the 15 minute warm-up with no sample line connected to the monitor it is possible to have
a false identification and value display of Enflurane.
With no gas reading (Agent Icon box with white X for agent identification and agent values of “--
-“) when Agent Vaporizer is first turned on, it may take 30 seconds to 1.5 minutes for agent
identification and reading to be displayed. Once identification is established, changes in
concentration are virtually immediate. With a 200% change in concentration, an auto Zero will
occur, and full accuracy of the changed concentration will be accomplished within approximately
30 seconds.
Whenever the Millennia®3155A’s Agent sensor changes from steady state condition, the
Millennia®3155A will perform an auto zero to restabilize the sensor readings. During this time,
15 seconds to 1.5 minutes, it is possible for a false identification and concentration value to occur.
Examples are as follows:
a. No gas, during warm-up and when sample line is disconnected.
b. Applying sample line for the first time.
c. When switching from one Agent to another.
d. Applying N2O in concentrations of 70% or more.
e. Going from N2O of greater than 50% to 0%.
f. When going from high Agent concentrations to low or off.

x
Precautions
Pressures
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.

SECTION 1
INTRODUCTION
1.0 INTRODUCTION.
1.1 Product Description. The Millennia®3155A/3155MVS Monitor is the Remote Control
Unit in the Invivo Research, Incorporated 3150 Series MRI Monitoring System. This monitor provides
Remote Control (through a cable or RF Radio Link) to a Omni-TrakTM 3150/MagnitudeTM 3150M
MRI Patient Monitor (located in the MRI Magnet Room). Used with the Omni-TrakTM 3150 MRI
Patient Monitor, the Millennia®3155A/3155MVS Monitor provides four waveform traces
compiling, processing, analyzing and displaying patient data from up to seven different patient
parameters. The information that this Monitoring System 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. There is no
direct patient connection to the Millennia®3155A/3155MVS Monitor (patient connection is
performed in the Magnet Room with the Omni-TrakTM 3150/MagnitudeTM 3150M MRI Patient
Monitor) except in the case of Agent monitoring when the Millennia®3155A is used with the patient
sample line connected directly into the front of the monitor. The Millennia®3155A/3155MVS
Monitor is compact, comes equipped with up to three batteries to supply emergency and/or transport
power plus may “float” between the Magnet Room and Control Room (as determined by the needs of
each unique monitoring situation). It also contains (as a optional feature) a recorder designed to
provide printouts of the concise charts and trends required by today's specialists for analysis and
documentation. The Millennia®3155A/3155MVS can be used inside the MRI Magnet Room when
positioned at or outside the 1000 Gauss (0.1T) Field Line. For the purposes of this manual, the Omni-
TrakTM 3150 and MagnitudeTM 3150M MRI Patient Monitors will be referred to as the 3150(M) and
the Millennia®3155A and 3155MVS Monitors will be referred to as the 3155A/3155MVS.
During MRI procedures that require anesthetic agents monitoring, where the 3155A is used in the
MRI exam room, the dual monitor system (software MDC01 and higher) allows the operator to
add a 3155MVS to the MRI monitoring system. The 3155MVS and 3155A interact through the
3150(M) to allow monitoring at a remote site (such as the MRI control room).
If operating a dual monitor system, the 3155MVS and 3155A patient monitors are interactive with
one another though the 3150(M). As the “communication unit” the 3150(M) acts to keep the
commands that control patient parameter function synchronized throughout the MRI monitoring
system. Should the 3150(M) 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(M) is turned on the system will synchronize and all patient configurations will reflect the
3155A configuration.
The 3155A/3155MVS Monitor provides control and display of the following Vital Sign
Parameters:
NOTE
The 3150(M) ETCO2 is turned Off when the Agent/ETCO2 is turned On at the Millennia®3155A.
When the Millennia®3155A is used to monitor Agent/ETCO2, it must be located in the Magnet
Room with the gas sample line connected directly to the front of the 3155A.

1.1.1 System Parameters. The 3155A/3155MVS 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.
1.1.2 User Interface. A simple to use interface has been developed to minimize operator learning
time. A Rotary Knob, which detents from selection to selection, is used to access the parameter menu's,
access the various setup features and finalize any changes to the setup of the monitor. Frequently used
menus (such as: Alarms, Trends and Recorder) have a Control Key which, when pressed, will open
the associated menu.
1.1.3 Versatility. With its complete offering of vital sign parameters, the 3155A/3155MVS
Monitor may be configured to meet the monitoring needs of a wide spectrum of patients from Neonate
to Adults. Every available parameter may be easily accessed and adjusted to the unique needs,
condition and situation of each patient.
1.2 Controls. Control of the Monitoring Features is provided through the use of a Rotary Knob;
as the operator turns the Rotary Knob (either clockwise or counterclockwise), with each detent the next
Vital Signs Display will become highlighted (selected) and, when the appropriate display is selected,
pressing the Rotary Knob will bring up the menu for the desired parameter. For adjustment of the
Operational Features, the front panel provides two different sets of control keys: the menu-select keys
bring up operational menus, while the direct control and operational keys provide manual control of
selected patient parameters.
Figure 1-1. The Front Panel
1.2.1 Front Panel Controls. (See Figure 1-1) The 3155A/3155MVS Monitor front panel consists
of one Rotary Knob, six Direct Control keys, four Menu-Select keys, five Operational keys, one
Alarm Silence key and the Power On/Off switch. The 3155A also contains an ETCO2/Gas Input Port
and additional graphics on the bottom of the front panel. The following is a general description of the
front panel controls.
a. The Rotary Knob. The Rotary Knob is located to the right of the Display Screen. The
function of the Rotary Knob is menu specific. For this reason, its various functions are
described throughout this document where it is used; in general, however, the Rotary
Knob operates as described below:
(1) As the Rotary Knob is rotated, either clockwise or counterclockwise, the
monitor display “scrolls” through the various screen items (screen icons, menu
options and patient parameters) which are available for selection. When the
appropriate item is “highlighted,” it may be selected by pressing and releasing
the Rotary Knob. All menus have a RETURN option which will return the
monitor to the previous menu selection.
