Reconnect the oxygen sensor to the connector on the printed circuit board. Carefully bring the two halves of the case together while positioning the wires to ensure they are not pinched between the two case halves. Make sure the sensor is fully inserted and in the proper orientation.

Reinsert the three screws and tighten until the screws are snug. Verify the unit operates properly.

The device will automatically perform a calibration and begin displaying % of oxygen.

6.2 MAXO2®+AE Model

Should the oxygen sensor require changing, the device will indicate this by presenting “Cal Err lo” on the display.

Unthread the sensor from the cable by rotating the thumbscrew connector counterclockwise and pull the sensor from the connection.

Replace the new sensor by inserting the electrical plug from the coiled cord into the receptacle on the oxygen sensor. Rotate the thumbscrew clockwise until snug.

The device will automatically perform a calibration and begin displaying % of oxygen.

7.0 CLEANING AND MAINTENANCE

Store the MAXO2® + analyzer in a temperature similar to its ambient environment of daily use.

The instruction given below describes the methods to clean and disinfect the instrument, sensor and its accessories (e.g. flow diverter, tee adapter):

Instrument

•When cleaning or disinfecting the exterior of the MAXO2® + analyzer, take appropriate care to prevent any solution from entering the instrument. Do not immerse unit in fluids.

•The MAXO2® + analyzer surface may be cleaned using a mild detergent and a moist cloth.

•The MAXO2® + analyzer is not intended for steam, ethylene oxide or radiation sterilization.

Oxygen Sensor

WARNING: Never install the sensor in a location that will expose the sensor to patient's

exhaled breath or secretions, unless you intend to dispose of the sensor, flow diverter and tee adapter after use.

•Clean the sensor with a cloth moistened with isopropyl alcohol (65% alcohol/water solution).

•Maxtec® does not recommend use of spray disinfectants because they can con- tain salt, which can accumulate in the sensor membrane and impair readings.

•The oxygen sensor is not intended for steam, ethylene oxide or radiation sterilization.

Accessories

•The flow diverter and tee adapter may be disinfected by washing them with isopropyl alcohol or Cidex (per manufacturer's instructions). The parts must be thoroughly dry before they are used.

•Sterilizing -The flow diverter and tee adapter may be sterilized using Cidex, steam or ethylene oxide (per manufacturer's instructions). Due to the varying conditions imposed on the materials during sterilization it is not possible to determine the exact number of times the sterilization processes can be carried out. Therefore, Maxtec® recommends that oper- ators carefully examine the flow diverter and tee adapter after sterilization and prior to use to verify that the item is fit for use. The operator should verify that there are no cracks and the item does not show any indication of material changes or physical damage that may compromise its effective use. Both flow diverter and tee adapter should be free of any chemical residue remaining from the sterilization process.

Because of the variability of the cleaning, disinfecting and sterilizing processes, Maxtec® cannot provide specific sterilization instructions, nor can the sterility of the item be ensured. Therefore, we highly recommend referring to the manufac- turer's instructions on the details of method.
