Pre-Use Checkout Procedure - Ohio Medical CVR Mode D'emploi

Pre-Use Checkout Procedure

WARNING ⚠ The Pre-Use Checkout Procedure must be performed
All tests must be performed with the regulator in its normal (vertical) operating
position, with a supply vacuum of 500 mmHg (66.7 kPa) minimum.
1. Turn the mode selector switch to O (Off).
2. Rotate the suction control knob one full turn clockwise (increase).
3. Clamp the connective tubing to occlude the fitting port. The gauge needle
should not move.
4. Unclamp the connective tubing.
5. Turn the mode selector switch to I (On).
6. Rotate the suction control knob fully counter-clockwise (decrease).
7. Clamp the connective tubing. The gauge needle should not move.
8. With the connective tubing clamped, increase the suction to 90 mmHg (12.0
kPa).
9. Slowly open and close the clamped tubing to create various flow rates
through the regulator. Check that the suction level is maintained at ± 5% of
full scale deflection when the tubing is clamped.
For Standard Two Mode Continuous, go to step 11.
10. High and Standard Three Mode Continuous ONLY
a. Turn the mode selector to MAX.
b. Clamp the connective tubing and check that the gauge needle
indicates the maximum available suction.
c. Turn the mode selector to | (On).
11. Low Continuous ONLY
Clamp the connective tubing and rotate knob fully clockwise (increase) to
verify the suction level does not exceed 135 mmHg ± 5 mmHg (18.0. kPa
± 0.7 kPa).
12. Reduce the suction level to zero and set the mode selector switch to O
(Off).

before using the equipment on each patient. If the
regulator fails any part of the Pre-Use Checkout Procedure,
it must be removed from service and repaired by qualified
service personnel.
