WARNING
Vital capacity

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.
Using manual ventilation cardiac bypass
1.
Set the Bag/Vent switch to Bag.
2.
Select Procedures.
3.
Select Start Cardiac Bypass.
The 'Cardiac Bypass' message shows in the waveforms and in
the general message field when manual ventilation cardiac
bypass is active.
4.
Select Close.
Using VCV cardiac bypass
1.
Start mechanical ventilation in VCV mode.
2.
Select Procedures.
3.
Select Start Cardiac Bypass.
PEEP is set to 5 cmH2O.
TV settings of less than 170 ml prior to starting cardiac bypass
remain at the set TV.
TV settings of more than 170 ml prior to starting cardiac bypass
change to 170 ml.
The 'VCV Cardiac Bypass' message shows in the waveforms
and in the general message field when VCV cardiac bypass is
active.
Note
PEEP and TV settings can be changed after entering cardiac bypass
mode.
4.
Select Close.
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.
