COMPONENT Description ITEM DESCRIPTION A Oxygen Concentration Dial A dial used for selecting oxygen concentrations between 21%-100%. The FiO2 scale is used for reference only. This Dial does not rotate 360°. The dial starts at 21% and ends at 100%. B Primary Outlet Port A male DISS oxygen fitting with check valve that delivers flow when engaged to any controlling device, such as a flowmeter.
Component Description ITEM DESCRIPTION F Air Inlet Fitting A male DISS or NIST air fitting with one way valve that is used to connect an air supply hose. Alarm An audible alarm that sounds due to an excessive pressure drop or deletion of either gas supply. Manifold Outlet (Optional) Manifold with 3 primary outlets. Rear Slide Mount with dove tail. G H I Installation WARNING • Read this User Manual before installing or operating the Air-Oxygen Blender.
Alarm Test 1. The Air-Oxygen Blender is installed and the flowmeter is turned on. Disconnect or turn off the air supply line to the Air-Oxygen Blender. 2. The Blender should alarm with a loud whistle noise. The whistle indicates the alarm is operating correctly. 3. Reconnect and activate the air supply line to the Blender, the alarm should stop whistling. 4. Disconnect or turn off the oxygen supply line to the Blender. 5. The Blender should alarm with a loud whistle noise.
3. To activate the bleed, turn the knurled collar until the bleed pin is engaged. Then slide the collar back until it contacts the cover. 4. Confirm the concentration of air/oxygen with an Oxygen Analyzer/Monitor. 5. Confirm the flow of air and/or oxygen mixture to the patient. 6. Turn “OFF” the Air and Oxygen supply when deactivating the Auxiliary bleed, and no device is attached to the outlet port. 7.
1. Disconnect all gas connections and equipment before cleaning. 2. Clean exterior surfaces with a cloth dampened with mild detergent and water. 3. Wipe dry with a clean cloth. Maintenance The following maintenance on the Air-Oxygen Blender must be performed by a trained service technician: • Every month verify proper functioning of alarm. • Every year conduct the Operational Verification Procedure (OVP). • Every 2 years the Air-Oxygen Blender should be serviced.
