n
With sustained unpredictable rhythms and a valid ECG Trigger, R-wave deflation
is automatically selected. The message
“Auto R-Wave Deflate”
will be displayed.
The deflation indicator will automatically be repositioned to the far right, “R-Trac” will
be displayed in the IAB deflation indicator. The system will return to predictive timing
once the rhythm becomes predictable.
n
Loss of trigger causes an alarm and pumping will stop.
Manual Operation Mode
n
Trigger source and timing of IAB inflation and deflation is determined by the operator.
n
Changing the trigger source will cause the pump to go to Standby. Pumping
will resume when the START key is pressed.
n
Leads I, II, III, AVR, AVL, AVF, V or External ECG source can be selected.
n
Timing must be readjusted by the operator if heart rate or rhythm changes.
n
Loss of trigger causes an alarm and pumping will stop.
n
Manual timing is typically used for pediatric IABP patients.
WARNING: The CS300 must be in Semi Auto Operational mode whenever no aortic
pulse is present, and IAB assist is desired. For example, whenever circulatory bypass
or a laminar flow, left ventricular assist device is in use.
Trigger Source
n
Trigger is the signal the CS300 uses to identify the beginning of the cardiac cycle.
n
The Trigger Source keys are only active in the SEMI AUTO and Manual Operation
Modes .
n
Regardless of the Operation Mode, the active trigger source is indicated by a flashing
diamond in the upper right corner of the screen.
ECG
n
The R wave of the ECG is the trigger event.
n
Pacer spikes are rejected.
n
ESIS (electrosurgical interference suppression) is automatic in this mode.
n
When using SEMI AUTO or Manual Operation modes, the ECG gain can be adjusted
from 0.15 to 3.00, relative to a normal gain of 1.0. The amount of gain will be
displayed next to ECG GAIN on the monitor screen. Go to Pump Options – ECG Gain
to adjust.
Pressure
n
The systolic upstroke of the arterial waveform is the trigger event.
n
The CS300 will automatically adapt the pressure trigger threshold to the systolic
pulse height of the arterial pressure waveform.
n
The pressure trigger threshold is displayed just below the trigger source on the
monitor screen and the arterial waveform is marked with a horizontal tick to indicate
the trigger point.
