Which statement is true regarding the use of nasal cannulas in emergencies?

A nasal cannula is specifically designed to provide supplemental oxygen to individuals who are breathing but may be in need of additional oxygen, making it more suitable for patients with conditions such as shortness of breath or certain respiratory diseases. In emergencies involving non-breathing individuals, other methods of delivering oxygen, like bag-mask ventilation, are necessary, as these approaches ensure that air is being actively delivered into the lungs.

The use of nasal cannulas is indeed limited to those who can breathe on their own, and it is not effective or appropriate for providing oxygen to someone who is unresponsive and not breathing at all. Therefore, recognizing the appropriate use of a nasal cannula is critical in emergency situations, and its limitations ensure that individuals receive the most effective care possible.
