5.5.3 About apnea backup ventilation
WARNING
HAMILTON MEDICAL recommends that apnea
backup ventilation be enabled whenever a mode
that allows spontaneous breathing is selected.
NOTE:
• When enabling apnea backup ventilation, verify
appropriate apnea backup control settings in the
Controls window.
• ASV® and INTELLiVENT
®
-ASV always work with
lung-protective rules strategies (C.3.3) and therefore
do not require additional backup ventilation.
This device provides apnea backup ventilation, a mechanism
that minimizes possible patient injury due to apnea or cessa-
tion of respiration. Apnea can occur in all modes except
(S)CMV, P-CMV, APVcmv, and ASV
®
. When the device is set
to one of these modes and no inspiratory efforts are detected,
or control breaths are delivered during an operator-set interval,
it declares apnea.
If apnea backup ventilation is enabled, ventilation continues.
The device’s apnea backup is bi-directional. This mean that
ventilation automatically resumes in the original support mode
if the apnea episode ends.
When apnea backup ventilation is enabled,
Backup is dis-
played at the top right-hand corner of the touch screen. Apnea
backup ventilation provides ventilation after the apnea time
passes with no breath attempts detected (set the
Apnea time
in the
Alarms -> Limits 1 window). When this occurs, the
device automatically (and immediately) switches into apnea
backup ventilation.
