Invasive pressures
zeroed arterial pressure: Art X, Fem X, or UAC X. If no arterial pressure is available, the
numerically first zeroed pressure is used.
Triggering intra-aortic balloon pumps
NOTE
1. Contact the balloon pump manufacturer for interface requirements. See the
technical specifications for the ECG analog output delay specification for the
acquisition device.
2. Connect a compatible analog output cable to the Defib Sync connector.
3. Adjust the invasive pressure filter. If arterial pressure is used to trigger the balloon
pump, use the 40 Hz pressure filter.
4. Primary displayed ECG lead: If the balloon pump triggers off the R wave of the
ECG, review the patient's ECG leads and place the one with the greatest amplitude
in the top (primary) position on the monitor display.
5. Pacemaker detection: If the patient has a pacemaker, be sure the pacemaker
detection is turned on. Failure to turn pacemaker detection on may cause poor
beat detection, which may result in inadequate triggering of the balloon pump.
Effects of IABP on displayed values
Displayed pressure values are affected by the intra-aortic balloon pump. The IABP
program displays three values, for example 150/45 (98). The first value is the systolic
value, the second is the diastolic value, and the third is the mean value. The displayed
numeric values are indicating a rapidly varying waveform generated during IABP
treatment and do not always reflect a true arterial blood pressure.
For accuracy and reliability, combine these recommended methods for reading
arterial and/or femoral blood pressure:
The IABP waveform displayed on the screen (use scales for evaluation)
●
The display on the balloon pump device, if available
●
Since there are a number of points along the IABP waveform that could be the
displayed value, it is important to know which points the program uses. The values
displayed will differ depending on the timing of the pump.
1:1 or 1:2 timing
Diastolic numerics: The displayed diastole always equals the balloon end diastole.
Systolic numerics:
When the augmented diastole is greater than the patient systole, the displayed
●
systole equals the augmented diastole.

If you choose to use the monitor for triggering, use the
following instructions. Failure to follow these instructions may
result in an incompatible analog output signal, which may
contribute to patient injury.
