Question

Quizplus · Accepted Answer

A nasal cannula is not effective for treating carbon monoxide poisoning as it does not deliver oxygen at a high enough concentration to displace the carbon monoxide from the hemoglobin molecules. Other forms of oxygen therapy, such as a non-rebreather mask or hyperbaric oxygen therapy, would be more appropriate for treating carbon monoxide poisoning. A nasal cannula can be used for long-term therapy for COPD, to decrease myocardial work, and to treat mild hypoxemia.
