QUICK CHECK PROCEDURE
NOTE:
HOME CAREGIVERS: Initial set up and verification of the
ventilator operation should be done by the caregiver in
conjunction with the Homecare Dealer or hospital provided
clinician. The Abbreviated Check Procedure may be performed in
the homecare environment to ensure proper set up and function of
the ventilator.
ABBREVIATED CHECK PROCEDURE
Inspection Check
NOTE:
Do this Inspection Check each time you turn on the HT50.
1. Remove the three screws from the inlet filter cover. Inspect
the filter. Replace if dirty. Re-install screws.
2. Examine the test lung and patient breathing circuit to ensure
there is no degradation of material which might cause leaks.
3. Examine the Oxygen Blending Bag (if used) to ensure there is
no degradation of material which might cause leaks.
4. Verify that the condition of the A.C. power cord is acceptable,
i.e. no frays. Connect the power cord to A.C. power source.
Exhalation Valve Calibration
NOTE:
Each time an exhalation valve is maintained or replaced
by another, such as when the complete circuit is changed, it must
be recalibrated. The valve must pass the calibration procedure
before it is used.
1. Connect the HT50 patient breathing circuit to the ventilator.
Connect the patient connection (exhalation valve) of the
breathing circuit to an adult (500 mL) test lung with restrictor
(LNG500A) or occlude the patient connection of the breathing
circuit.
2. Press the On/Standby button once to enter Settings
condition.
3. Press the Manual Inflation button once, then again within
three seconds.
4. The HT50 will start the EZ Cal and the ventilator will
automatically test the exhalation valve. If it passes the test,
the messages "Cal Completed", then "Press ON to Vent" will
be displayed.
4a. If the test fails, the message "Cal Failed" will be displayed.
