Trigger Selection In Autopilot; Mode - Arrow AutoCAT 2 Series Operating Manual

Trigger Selection in AutoPilot

When Autopilot mode is selected, the pump will choose the trigger mode based on
information available from the patient and on the IABP settings selected by the user.
The following is the trigger mode selection criteria in AutoPilot
Trigger mode
PATTERN (Default)
PEAK
AFIB
VPACE
APACE
AP
NOTE: Arrhythmia detection criteria: 8 of the last 16 beats vary more than 15% on a
beat to beat basis.
NOTE: APACE trigger may be selected when an ECG or AP signal are present but are
not yet stable.
NOTE: In the event that there are more than 3 trigger switches between Peak and
Pattern within 1 minute, the pump will automatically select PEAK trigger for 3 minutes.
This allows timing and triggering to be more stable during periods of significant heart
rate changes and/or an unstable ECG signal. This selection will be indicated by PEAK
trigger being displayed in light Blue in the trigger area of the display. In the event that
Peak trigger becomes unavailable or an arrhythmia is detected the pump will
automatically select the appropriate trigger mode based on current patient conditions.
