Which device is used to deliver supplemental oxygen to patients?

The use of supplemental oxygen is critical in emergency medical situations where a patient may be experiencing hypoxia or other respiratory issues. Nasal cannulas and non-rebreather masks are common devices employed in these scenarios, and each serves a specific purpose for the delivery of oxygen.

A nasal cannula is a flexible tube that fits into the nostrils and can deliver low to moderate levels of supplemental oxygen, making it suitable for patients who require assistance but can still breathe on their own. It allows for more mobility and comfort compared to other devices.

On the other hand, a non-rebreather mask is designed for more severe cases of hypoxia. It covers the nose and mouth and has a reservoir bag that provides a higher concentration of oxygen. Additionally, it has one-way valves to prevent the patient from breathing in exhaled air, ensuring that they receive mostly oxygen with minimal dilution from ambient air. This mask is particularly effective for treating patients in critical condition who need immediate and concentrated oxygen.

Together, these devices are crucial tools in an EMT's arsenal for providing supplemental oxygen and significantly improving patient outcomes during emergencies.
