What is the purpose of a nasal cannula, and what is a PT consideration?

• A. Purpose: supplemental oxygen; PT: place cannula incorrectly to test tolerance.
• B. Purpose: humidify inhaled air; PT: maximize mobility without oxygen.
• C. Purpose: deliver nebulized medications; PT: ambulation allowed without oxygen.
• D. Purpose: supplemental oxygen; PT: ensure proper placement and portable tank for ambulation.

Answer: (D)

The main idea is that a nasal cannula is used to deliver supplemental oxygen to help keep a patient’s blood oxygen levels adequate during activity. In a physical therapy setting, a key practical consideration is to ensure the cannula is properly placed and that a portable oxygen source is available for ambulation. Proper placement keeps the flow consistent and reduces skin irritation, while a portable tank allows the patient to move during therapy without losing oxygen supply. Throughout the session, confirm the flow rate meets the patient’s needs, monitor oxygen saturation, and secure the tubing so it won’t snag or pull loose during movement. Humidification or nebulized medications aren’t the primary purposes of the cannula, and ambulating with no oxygen is not appropriate for someone who requires supplemental oxygen.
