Parker Porter Nitronox Scavenger Plus Quick Start Manual

1. Pre-Check
Note: To perform these tests, gas supply cylinders or gas supply shutoff valves are required in order to isolate the
gas supply form the device. Attempting to perform these tests with central pipeline supplied gas without a
local shut off mechanism is not recommended.
WARNING: Proper inspection and maintenance of this device is essential to prevent gas leaks. All
hoses, fittings, and connections should be inspected regularly, and all leaks should be repaired
immediately.
WARNING: If precheck test cannot be executed successfully, do not use this device and contact
distributor.
Under-Pressure Valve Open Test
1 Ensure the vacuum is turned on
Adjust to maximum vacuum (turning the flow control
2 knob counterclockwise,
between 3 - 8 inHg)
Create a seal by placing your hand over the inlet
3
(patient) port
If you feel vacuum (suction on your hand and/or gauge
4 changes), contact your authorized distributor for
service and troubleshooting
Leak Test
1 Ensure the vacuum is turned off (turning the flow control knob clockwise until tight or shut off vacuum source)
2 Using the breathing circuit, exhale into the reservoir bag until full
3 Monitor the time it takes for the reservoir bag to completely deflate
If the reservoir bag completely deflates within 30 seconds, contact your authorized distributor for service and

2. Operating Instructions
Before initiating administration of analgesic gas, slowly turn the flow control knob
1 (1) on Nitronox Scavenger Plus counterclockwise until the pressure displayed on
the vacuum gauge (2) is within the green band (-3 to -8 inHg).
Begin administering analgesic gas in accordance with the mixing device's instructions for use.
2
Once the procedure begins, the reservoir bag may slightly inflate upon patient
exhalation. Monitor the reservoir bag to ensure the reservoir bag goes from deflated
(1) to slightly inflated (2) when the patient exhales, then deflates again before the
next exhalation.
3
The pressure displayed on the Nitronox Scavenger Plus should be maintained at
the lowest setting that allows complete deflation of the bag between patient breaths.
If the reservoir bag begins to accumulate gas, increase the vacuum flow by adjusting
the flow control knob.
Note:
If the reservoir bag continues to fill even after completely opening the flow control knob, check that the vacuum
supply is ON, there is an adequate vacuum source pressure (10 to 21 inHg), the device is set to the correct
vacuum pressure (3 to 8 inHg), the vacuum hose is properly connected, and there are no kinks in the vacuum
hose. If gas continues to accumulate, contact your authorized representative for troubleshooting.
WARNING: Operation of the device outside of the green band may not provide adequate scavenging.
Operation under these conditions requires monitoring of the reservoir bag. If the reservoir bag does not
deflate after exhalation, and the vacuum gauge is below the green band, use of N
discontinued.
