15.4. BACKUP VENTILATION MODE
Note: Backup will not occur when the user inserts weight, selects
a ventilation mode and does not press OK . In this situation, a trig-
ger is received from the patient and the respiration is performed
according to the ventilation mode.
Backup mode is an alternative ventilation method taking place when the
ventilator patient circuit is connected to the patient in these situations:
1. If during CPAP ventilation, the patient stops initiating spontaneous
breaths from more than 10 seconds for pediatric (5KG) and more
than 25 seconds for an adult (70+ KG), an Apnea alarm appears.
2. Patient is connected to the ventilator, and for some reason, the user
did not start ventilation after connecting the patient. The backup
starts after three breaths.
3. Patient is connected to the ventilator, and user has paused venti-
lation. In this case when trigger is sensed by the ventilator, the ven-
tilation will automatically resume.
The result of using this backup mode is that the patient will be ventilated in
case of losing the ability to initiate spontaneous breaths in CPAP mode, or
if an emergency or user error has occurred in the preliminary stages of
ventilation setup, or when pausing the ventilator for some reason without
resuming ventilation.
15.4.1. BACKUP VENTILATION IN CPAP
If during CPAP ventilation, the patient stops initiating spontaneous breaths
from more than 10 seconds for pediatric (5KG) and more than 25 seconds
for an adult (70+ KG), an Apnea alarm appears.
Then backup ventilation is initiated:
The screen displays an alarm: "Apnea Detected" and the "OK" button for
user approval appears. Ventilation will start even if user has not pressed
OK . Alarm will appear on the screen while audio prompt is activated.
•
Volume, Pressure, MV and all other alarms which are patient weight-
based remain unchanged.
•
Ventilation method is changed to SIMV - VC - PS with the last patient
weight parameters dialed in.
