ProcedureforAdministeringOxygenviaNasalCannula.

Materials:

Nasalcannula.

Oxygensource(e.g.,oxygentankorconcentrator)。

Flowmeter.

Humidifier(ifdesired)。

Steps:

1.Verifyoxygensourceandequipment:Ensurethatthe

oxygentankorconcentratorisproperlyconnectedand

functioningandthattheflowmeteriscalibrated.

2.Assesspatient:Checkthepatientsrespiratory

status,includingrate,depth,andpattern.Auscultate
