    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.
  • Page 11 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.
  • Page 12 Precautions 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).

    INTRODUCTION. ® 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-Trak 3150/Magnitude 3150M MRI Patient Monitor (located in the MRI Magnet Room).

  • Page 20: 1.1.1 System Parameters

    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.
  • Page 21 During normal operation each active parameter has a Menu-Select icon on the screen. When the Rotary Knob is rotated, the Menu-Select icon which is being pointed at becomes “highlighted.” Rotating the Rotary Knob will cause the monitor to “scroll through” the available menu selections. Once the appropriate Menu-Select icon is highlighted, pressing the Rotary Knob completes the selection and brings up the required menu.
  • Page 22 FREEZE. (Item 5) The 3155A/3155MVS Monitor freezes the ECG waveform from Trace A for closer examination upon user demand. When the ECG trace is active, pressing the FREEZE key will freeze it into the Trace B location while Trace A remains active. When the trace is frozen, pressing the FREEZE key will release it.

    Verify the accuracy and proper functioning before using the monitor on a patient. Never use a monitor that is suspected of being inaccurate or out of calibration. Verify that the Waste Gas Port (on the back of the monitor) is connected to the Gas Scavenging System.
  • Page 33 NOTE If operating a dual monitor system, the first 3155 to establish a communication link with the 3150(M) will become the “system master.” This means that all interactive parameters throughout the system will synchronize with this 3155. Therefore the operator needs to ensure that the 3155 that contains the desired setup is turned on, and linked, before power is applied to the second 3155.

    Invasive Pressure Monitoring. The 3155A/3155MVS Monitor provides up to two invasive pressure channels. Most invasive pressure monitoring functions are contained in two primary menus: P1 and P2 (if the operator has selected labels for these, the menu name will be the selected Label).
  • Page 54 Figure 4-6. The P1 Menu (ART Selected) SET LABEL. (See Figure 4-7) Scrolls through a list of labels to be put next to the mean pressure numerics to help the user to identify the transducer site. The options are ART, PAP, CVP, LAP, ICP, and NONE (default). The selected label, not only becomes the Pressure Channel menu title, it determines the color of the visual display.

  • Page 55: Alarm Limits

    The heart rate is displayed in the ECG parameter box, and it is annotated with its source (e.g., “60 (P1)” indicates a heart rate of 60, derived from the arterial pressure). If AUTO is chosen, the heart rate is obtained automatically from the highest priority active input.

  • Page 56: Theory Of Oscillometric Measurement

    Non-Invasive blood pressure monitors are sensitive to patient motion artifact. Such artifact can cause readings to be slow or even an incorrect pressure reading. Visual checks of the patient, other vital signs and checking the limb to which the cuff is attached should be standard routines with NIBP use.

  • Page 57: Associated Displays

    With continued cuff pressure reduction, the underlying artery is open throughout the cardiac cycle, and the arterial wall movement is less. The cuff pressure oscillations begin to decrease in amplitude until they become uniform. The point at which the amplitudes become uniform is diastolic pressure. NOTE The point of maximum oscillations is coincident with mean arterial pressure regardless of arterial elasticity so long as the ratio of air volume in the cuff to the volume of the artery under compression...
