When should oxygen be administered to a patient?

Oxygen should be administered to patients who are lethargic or short of breath because these symptoms often indicate that the body is not receiving adequate oxygenation. When a patient presents with lethargy or difficulty breathing, it is essential to assess their oxygen saturation levels and provide supplemental oxygen to support their respiratory function and enhance tissue oxygenation. This is particularly important in emergency situations where hypoxia (low oxygen levels) could lead to serious complications or even death.

Lethargy can be a sign of several underlying conditions, including respiratory distress, pneumonia, or chronic obstructive pulmonary disease (COPD), among others. Providing oxygen in such cases can help alleviate the symptoms and stabilize the patient until further medical intervention is available. Ensuring that the patient receives adequate oxygen can improve their overall condition and potentially reverse some of the lethargy caused by hypoxia.

While oxygen administration might also be relevant in cases of suspected stroke or other emergencies, the primary focus is on patients who are showing clear signs of oxygen deprivation. In those scenarios, administering oxygen is a critical response to ensure patient safety and improve outcomes.
