2.2 Use

2.2.1 Procedure

Note: Prior to use, always test the batteries and alarms (if applicable). Also check calibration, the sensor for leaks and damage, and the alarm settings.

The AX/MX300-I instruments can be used to measure a gas mixture for oxygen in two basic modes:

In the inhalation side of breathing circuit ahead of antibacterial filters, humidifiers and medicating devices.

In confined volumes such as incubators or tents.

When monitoring for oxygen in breathing circuits, the flow diverter must be used. The diverter should be screwed onto the threaded front end of the R17MED sensor. A tee adapter (plastic, P/N A268, or metal, P/N A283) should be placed into the circuit, and the above sensor assembly plugged into the tee adapter. See Figure 2-1.

CAUTION: CHECK THE BREATHING CIRCUIT FOR LEAKS. BE CERTAIN THAT THE CIRCUIT DOWNSTREAM OF THE SENSOR DOES NOT PRODUCE ANY BACKPRESSURE OR RESTRICTION TO FLOW. ERRORS IN READINGS WILL RESULT IF THIS IS NOT FOLLOWED.

THE OXYGEN SENSOR IS A NON-STERILE DEVICE AND SHOULD BE USED IN CONJUCTION WITH AN ANTIBACTERIAL FILTER. ALWAYS INSTALL THE SENSOR ON THE INSPIRED LINE AHEAD OF FILTERS, HUMIDIFIERS AND MEDICATING DEVICES. NEVER EXPOSE THE SENSOR TO PATIENT’S EXHALED BREATH OR SECRETIONS UNLESS YOU INTEND TO DISPOSE OF THE SENSOR AND FLOW ADAPTER AFTER USE.

When monitoring for oxygen in confined volumes such as incubators, hoods, etc., the flow diverter must be removed from the
