If oxygen does not seem to flow, first verify that the flowmeter ball is
registering a flow. Then, place the tip of the cannula into a glass of water; if
bubbles come out of the cannula, oxygen is flowing. If bubbles do not
appear, refer to Section 5.0. Troubleshooting.
To prevent a voided AirSep warranty, follow all manufacturers’
instructions.
Replace the disposable cannula periodically following normal usage
according to your Equipment Providers recommendations.
