PLT093: Administration of Medical Oxygen

What code PLT093 covers, why the FAA tests it, and how to study Administration of Medical Oxygen before your checkride.

Official FAA learning statement

Recall administration of medical oxygen

What this means for your checkride

Supplemental oxygen keeps the blood saturated as cabin altitude climbs and the air thins. Systems deliver it in different ways, continuous flow, diluter-demand, and pressure-demand, matched to altitude, and pilots use only aviator's breathing oxygen. The regulations require it for the crew above set cabin altitudes and for passengers higher still.

Without oxygen at altitude, hypoxia sets in without warning, so the FAA tests when oxygen is required, the correct type, and how the delivery systems differ.

The common trap

Pilots assume any oxygen will do or that they will feel hypoxia coming. Only aviator's breathing oxygen is approved, and hypoxia impairs judgment before you notice symptoms, which is why the altitude rules are firm rather than left to how you feel.

Before your checkride (14 CFR 61.39)

A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
