7.5 Digital gauge. Ohio Medical Push-To-Set Continuous Vacuum Regulator
Below you will find brief information for Vacuum Regulator Push-To-Set Continuous Vacuum Regulator. The Push-To-Set Continuous Vacuum Regulator is a lightweight, compact unit used throughout the hospital primarily for pharyngeal/tracheal suctioning (airway management). Various models provide regulated or full-line vacuum for hospital suction procedures.

7.4.2 Assembly 8.1 Set-up
1. Carefully insert and tighten the timing valves.
3. Rotate each clockwise about 3 turns form thread engagement.
1. Verify that there is 500 mmHg ± 10 mmHg (67 kPa ± 1.3 kPa) vacuum on the supply gauge.
2. The supply open fl ow must be 50 LPM minimum.
3. Connect the supply vacuum to the adapter port.

1. Remove digital gauge as described in 7.2.2.
2. Using a small fl at head screwdriver, push batteries out at a 45 o angle.
7.5.2 Inserting Batteries
1. Place negative side of battery into battery slot fi rst
(battery will be at an angle).
2. Then using a fl at head screwdriver, gently push in positive battery contact while sliding battery in place.

Test
1. Connect the 10 LPM Flowmeter to the patient port.
2. Set 200 mmHg/26.6 kpa on the gauge and keep the knob pushed in.
3. Make certain leakage at the patient port connection is no more than 1 LPM.
4. While observing the fl owmeter, push and rotate the knob. Leakage should be no more than 1 LPM. Replace the knob. It should fully return.
8.3 Gauge Test
Note: All Ohio Medical gauges are supplied with an accuracy of ±5% of full scale defl ection throughout their range. The table below is provided for reference.
Note: Digital Gauges are supplied with an accuracy of
±1% of full range at 22 o
C
Note: All gauge needles should come to rest within the zero range bracket or return to the stop pin when no suction is being supplied. Gauges which do not comply may be out of calibration.
When checking gauge accuracy, be sure that the calibration gauge has an accuracy of 1% of full scale defl ection or better.
