How should oxygen therapy be safely managed by CNAs when a resident uses a nasal cannula?

• A. Increase flow rate if resident complains of dyspnea.
• B. Remove nasal cannula during meals.
• C. Do not adjust flow rate; ensure tubing is secure and unobstructed; report issues to nurse; keep tubing clean.
• D. Adjust tubing to loosen for comfort.

Answer: (C)

Safety in delivering oxygen with a nasal cannula relies on keeping the delivery steady and free from problems. The CNA’s job is to ensure the tubing stays secure and unobstructed, is clean, and is positioned so it won’t be easily dislodged. The flow rate and any changes to the oxygen prescription are not within a CNA’s scope; those decisions are made by a nurse or physician. If the resident appears to have trouble breathing, the tubing seems dislodged, or there’s a leak or skin irritation, report it to the nurse right away rather than adjusting the settings. The cannula should remain in place and be maintained correctly during activities, including meals, unless there is a specific instruction to remove it.
