How is oxygen typically administered to patients by EMTs?

Oxygen is commonly administered to patients by EMTs using various devices designed for different levels of oxygen delivery and patient needs. The nasal cannula and non-rebreather mask are two of the primary tools used in pre-hospital settings.

A nasal cannula allows for supplemental oxygen delivery while enabling the patient to talk and breathe normally through their mouth. This device is typically used for patients who require mild to moderate oxygen therapy, as it delivers oxygen directly into the nostrils.

The non-rebreather mask provides a higher concentration of oxygen and is used for patients who are experiencing more severe respiratory distress or hypoxia. This mask has a reservoir bag attached that fills with oxygen, allowing the patient to receive as much as possible with each breath while preventing room air from entering.

These methods are effective and practical for EMTs to quickly and efficiently provide necessary oxygen to patients in various emergency situations. In contrast, other methods such as intravenous lines or intubation are not standard practices for immediate oxygen delivery in the pre-hospital environment. Intravenous lines are primarily used for medication administration and fluid replacement, while intubation is an advanced procedure that requires a higher level of training and is generally reserved for more critical situations.
