Prescribing supplemental oxygen.

Oxygen is a pharmacological agent and requires prescribing by appropriate indications. Indications differ between the patient in an unsteady medical state and one in a chronic hypoxic state. Reimbursement issues must always be a consideration when prescribing, as well as the method of delivery of oxygen. Alternative delivery systems are currently available. The NP must provide proper assessment, education, and follow up evaluations of the effectiveness of the medication.
