If your organization uses "Christmas tree" adapters, which connects the oxygen tubing to the flow meter, make sure you are not reusing single-use versions of these devices.

For these and all devices, ensure that if packaging states "single patient use" or "single-use only" or has the number 2 circled with a strike through it, you do not reuse and will discard/change the device between patients.

If your facility uses the stainless-steel, reusable version of the Christmas tree adapter, ensure that you have specific disinfection instructions from the manufacturer and accountability for cleaning between patients. This device is difficult to disinfect, hence a more common approach is to use disposables.
