Step 8-
adjust inspiratory effort for pre-set CPAP level, for proper patient
triggering.
NOTE THAT IT IS ESSENTIAL WITH THE TRIGGERED DEMAND FLOW OF THE
IC-2A, THAT THE INSPIRATORY EFFORT BE PROPERLY ADJUSTED TO
ASSURE THAT THE PATIENT CAN OBTAIN GAS.
As in the SIMV mode, no external constant flow source is necessary.
Step 9-
connect to patient and observe pressure gauge. Adjust inspiratory time
and/or flow rate to assure that sufficient gas is provided and that the
CPAP level is maintained.
In CPAP, only the demand indicator will be activated.
D. MANUAL CYCLING
Step 1-
set CYCLE/CPAP-MANUAL selector to CPAP-MANUAL position.
Step 2-
set NORMAL/SIMV selector to SIMV. Set expiratory time to maximum.
Step 3-
set desired inspiratory flow rate and inspiratory time.
Step 4-
set maximum pressure level (rear panel control) by occluding patient port,
depressing manual control and adjusting maximum pressure.
Step 5-
adjust PEEP level in manner similar to maximum pressure, if it is desired
to have PEEP during manual cycles.
Step 6-
ventilate test lung by depressing manual button and observing pressure
gauge for proper operation.
Step 7-
connect to patient and ventilate by depressing manual button long
enough on each cycle to set the inspiratory timer. If the manual button is
held in longer than the preset inspiratory time, then inspiration will
continue during the entire time that the manual button is depressed.
Observe chest excursion and pressure gauge for proper operation.
