8.3 Flow Test. Ohio Medical Pediatric ISU, ISU
The ISU and Pediatric ISU are vacuum regulators that provide either intermittent or continuous suction. They are used for NG (intermittent) or pharyngeal/tracheal (continuous) suctioning throughout the hospital. The Pediatric ISU has a maximum vacuum limit of 135 mmHg (18.0 kPa), which can be adjusted between 80 and 150 mmHg (10.7 and 20.0 kPa).

8.3 Flow Test
1. Remove the bubble leak tester from the supply vacuum connection and connect the supply vacuum directly to the regulator adapter port.
2. Set the supply vacuum to 500 mmHg ± 10 mmHg
(66.7 kPa ± 1.3 kPa) on the supply vacuum gauge.
8.3.1 Continuous Mode Flow Test
1. Connect the regulator fitting port to the 50 LPM flowmeter.
2. Turn the mode selector knob to | (CONT).
3. Rotate the suction control knob fully clockwise
(increase).
4. Verify that the flow rate exceeds :
Adult ISU: 40 LPM
Pediatric ISU: 25 LPM
8.3.2 Intermittent Mode Flow Test
1. Pull the nameplate wrench from the front of the regulator to access the flow control valve.
2. Occlude the regulator fitting port.
3. Turn the mode selector knob to | (CONT).
4. Set 120 mmHg (16.0 kPa) on the regulator gauge.
5. Turn the mode selector knob to O (OFF).
6. Connect the regulator fitting port to the 10 LPM flowmeter.
7. Turn the mode selector knob to |O|O| (INTER).
8. Locate the flow control valve in the regulator.
9. The flow rate must be adjusted during the “On” cycle of the intermittent mode. Using the proper tool, either a Phillips head screwdriver or a ball hex key wrench, adjust the flow control valve to produce a flow rate of 8 LPM. To increase the flow rate turn the valve counter-clockwise. To decrease the flow rate turn the valve clockwise.
