BIO-MED DEVICES IC-2A - Continuous Positive Airway Pressure (Cpap)

23
inspiratory effort sensor detects a negative pressure.
Step 3- set PEEP level, making certain to readjust the inspiratory effort control to
compensate for PEEP.
Note:
In the SIMV mode it is unnecessary to add an external constant flow source due to
the triggered demand flow system. It is necessary, however, that the inspiratory
effort control be properly adjusted at all times to assure proper operation.
Step 4- observe assisted breath following termination of expiratory time. Adjust
tidal volume equal to inspiratory time X flow rate to proper level.
Note:
In the SIMV mode, in the event no patient inspiratory effort is sensed for a period of
ten seconds, a "backup timer" will provide a "backup breath." Every time an
inspiratory effort is sensed, whether for a spontaneous or an assisted breath, the
backup timer is reset.
The interval between assisted breaths may still be set to the maximum expiratory
time of at least 45 seconds.
In SIMV, the demand indicator alone will show spontaneous breaths, while both
demand and cycle indicators together indicate an assisted breath or a backup
breath.
C. CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP)
NOTE:
WHENEVER THE IC-2A IS TURNED OFF, DISCONNECT THE PATIENT BEFORE
TURNING THE VENTILATOR BACK ON, IN ORDER TO AVOID ERRONEOUS
BREATHS.
THE MAXIMUM PRESSURE CONTROL MUST BE TURNED OFF (FULLY
CLOCKWISE) IN THE CPAP MODE.
Step 1- set PEEP/CPAP control fully clockwise (zero).
Step 2
- set CYCLE/CPAP-MANUAL switch to CPAP-MANUAL position.
Step 3- turn expiratory time control fully clockwise to maximum.
Step 4
- set NORMAL/SIMV switch to SIMV.
Step 5
- adjust inspiratory time and flow rate to give administered gas volume
sufficient to meet patient demand.
Step 6- connect to test lung.
Step 7- set desired CPAP level using the PEEP/CPAP control.
