Autopilot /Operator Control Keys; Autopilot ™ Timing Methods - Arrow AutoCAT 2 Series Operating Manual

AutoPilot /Operator Mode Control Keys
™
The main function key is the OPERATIONS MODE key, which selects either
AUTOPILOT or OPERATOR mode. The user should choose the operation mode prior to
setting up the AutoCAT ® 2 Series for patient use. The LED's indicate the selected mode.
AutoPilot (Default mode): When AutoPilot
™
automatically select and change ECG and AP sources, trigger mode and timing settings
to maintain optimal counterpulsation.
Automatic Signal source selection: When the AutoPilot
monitor and analyze all available ECG and AP signals. It will select either the best
signal as determined by several factors or the first available signal if only one signal is
present. If all signals are similar, then ECG Skin, Lead II and AP FiberOptix
preferred signals. If a signal is lost or becomes erratic, the pump is continuously
analyzing all other signals in the background. It will choose the best signal from those
which are available. The system is designed to maintain optimal triggering whenever
possible. If triggering cannot be maintained a Trigger Loss alarm will be issued.
Automatic timing: The pump determines the optimal timing method and timing settings
based on the signals which are available and then based on further analysis of the
ECG/AP and BPW waveforms. The system can detect irregular rhythms and
implements special timing algorhythms for these circumstances. The following table
shows the timing methods and signal which are needed:
