How to clean and disinfect the flow sensors

Do not autoclave plastic flow sensors.

Do not use high-pressure gas, or brushes to clean the flow sensors.

Do not use cleaning solvents that are not approved for use with

Polycarbonates (e.g. CIDEX Plus).

CIDEX sterilization Both Datex-Ohmeda and the manufacturer of CIDEX (Johnson & Johnson)

have tested this procedure.

• CIDEX must be 14 day mixture, with activator vial REF REORDER # 2245

• One liter of this solution cleans four (4) flow sensors

Procedure (Figure 2-3) 1. Remove the flow sensor module from the absorber. Refer to “Disassemble

the patient path” in this section.

2. Remove the flow sensors from the module.

• Push in the latch.

• Pull off the cover.

• Remove the flow sensors.

3. Submerge the flow sensor and tubes in activated CIDEX solution. Keep the

connector dry.

4. Keep the solution in the tubes for the sterilization period.

5. Submerge the flow sensor and tubes in distilled water. Again, do not get the

connector wet.

6. Rinse as indicated in CIDEX instructions.

7. Do steps 5 and 6 again to remove all CIDEX.

8. COMPLETELY dry the flow sensor and the tubes before you use the sensor.

Use a dry syringe, or connect vacuum or pressure to remove all liquid from the

sensor (sensor, tubes, and connector):

•Minimum time: 1 min

•Maximum vacuum: 30 in Hg

•Maximum flow: 10 L/min flow

•Maximum pressure: 345 kPa (50 psi).
