alarms are suspended. The alarms are enabled when VCV cardiac
bypass is turned off or mechanical ventilation is stopped.
Manual ventilation cardiac bypass and VCV cardiac
bypass modes should only be used when the patient is
receiving extra-corporeal oxygenation by means of a
heart-lung machine. These modes of ventilation are not
intended to provide metabolic levels of ventilation to the
patient.

Vital capacity
Use the Vital Capacity procedure to deliver a pressure breath for a
set time. The Vital Capacity procedure provides a simple way to
deliver one pressure breath during mechanical ventilation without
making multiple ventilator setting changes. The
PEEP on Exit
setting provides a way to change the ventilation PEEP setting
automatically at the end of the Vital Capacity procedure.
