When should an EMT consider applying oxygen?

Administering oxygen is an essential intervention for EMTs, particularly in scenarios where a patient exhibits signs of respiratory distress or hypoxia. Hypoxia refers to a condition where the body or a region of the body is deprived of adequate oxygen supply, which can lead to serious complications if not promptly addressed.

In cases of respiratory distress, the patient's ability to adequately take in oxygen is compromised, which warrants immediate attention. Signs of respiratory distress can include increased respiratory rate, shallow or labored breathing, cyanosis (bluish coloration of the skin), or alterations in mental status. Administering supplemental oxygen can help alleviate these symptoms and improve oxygen saturation in the blood, thereby preventing potential deterioration of the patient's condition.

While low blood pressure or being conscious and alert are important considerations in patient assessment and management, these factors do not directly indicate a need for oxygen administration. A patient may have low blood pressure for various reasons unrelated to oxygenation, and a patient who is conscious and alert may still be hypoxic or in respiratory distress. Recognizing and responding to signs of hypoxia or respiratory distress is paramount to providing effective prehospital care.
