n
When using the SEMI AUTO or Manual Operation modes , a fixed pressure threshold
can be manually set. Go to Pump Options - Pressure Threshold to adjust.
When using PRESSURE , the balloon must be fully deflated before the upstroke
of systole.
CAUTION: If an irregular rhythm develops while using pressure trigger, the CS300 will
automatically adjust deflation timing early to avoid interfering with systolic ejection. Do
not attempt to adjust the deflation control. Pressure triggering is NOT recommended for
use with sustained irregular rhythms.
Pacer V/A-V
n
This trigger mode is only available in the SEMI AUTO and Manual Operation
modes .
n
The ventricular spike of a ventricular or an atrial-ventricular pacemaker is the trigger
event.
n
Patient must be 100% paced.
n
It is typically used when ECG triggering is unsuccessful and a ventricular or
atrial-ventricular sequential pacemaker is in use.
Pacer V:
Assists 100% ventricular paced rhythms up to a rate of 185 beats per minute.
Pacer A-V: Assists 100% atrial-ventricular paced rhythms provided the A-V interval
is between 80-224 msec. and the pacing rate is less than 125 beats per minute.
Pacer A
n
This trigger mode is only available in the SEMI AUTO and Manual Operation
modes .
n
The R-wave of the ECG is the trigger event.
n
Atrial pacer spikes are enhanced and rejected.
n
Atrial pacemaker pulse rejection time is expanded in this mode.
n
This trigger mode is recommended only if atrial pacer tails interfere with R-wave
detection when using the ECG trigger.
n
Fixed or demand atrial pacing can be used in this trigger.
CAUTION: Never use Pacer A trigger in the presence of a ventricular paced rhythm.
Internal
n
This trigger mode is only available in the SEMI AUTO and Manual Operation modes .
n
Internal trigger is used when there is no mechanical cardiac cycle, i.e. cardio-
pulmonary bypass or asystole.
n
In normal Operation, the rate is fixed at 80 BPM.
n
The internal trigger rate can also be adjusted from 40 to 120 BPM, in increments of 5
BPM. Go to Pump Options – Internal Rate to adjust.
NOTE: If an R-wave is detected when using this mode, the System automatically
deflates the IAB and the message ECG Detected will be displayed on the monitor
screen.
WARNING: Never leave the system set in the Internal Trigger Mode if the patient is
generating a cardiac output.
