A patient’s chart indicates home oxygen use of 3.0 L/min, with orders to start without supplemental oxygen and add 1.0 L/min if SpO2 is less than 89%. What is the BEST action for the tech?

A patient’s chart indicates home oxygen use of 3.0 L/min, with orders to start without supplemental oxygen and add 1.0 L/min if SpO2 is less than 89%. What is the BEST action for the tech?

• A. Leave the patient on 3.0 L/min for the study
• B. Start the study at 1.0 L/min
• C. Call the physician for confirmation
• D. Follow the physician's orders

Answer: (C)

The situation hinges on a safety check: oxygen therapy orders must align with the patient’s actual needs and with what’s documented in the chart. Here, the patient is on home oxygen at 3 L/min, but the order for the sleep study says to start without supplemental oxygen and only add 1 L/min if SpO2 falls below 89%. That mismatch creates a risk if the tech acts without clarification. Because the clinician’s intent isn’t clear from the conflicting notes, the correct immediate step is to contact the physician to confirm how the oxygen should be handled during the study. Oxygen administration during testing has safety and study-interpretation implications, and changing or discontinuing a patient’s established oxygen therapy without explicit authorization can provoke hypoxemia or other adverse events, or skew study results. In short, verify with the ordering physician what should be done about oxygen for this patient before proceeding.
