What is the primary purpose of administering oxygen during a medical emergency?

The primary purpose of administering oxygen during a medical emergency is to improve oxygen saturation in the blood. When a patient is in a critical situation such as respiratory distress, shock, or other forms of hypoxia (low oxygen levels), their body's tissues and organs may not be receiving the oxygen they need to function properly. By providing supplemental oxygen, the healthcare provider can increase the amount of oxygen available in the bloodstream. This is crucial for ensuring that vital organs, like the brain and heart, receive adequate oxygen to maintain their function and prevent further complications or damage.

Additionally, while pain relief, tranquilization, and increased blood circulation are important in various medical scenarios, they do not directly address the immediate need for oxygen in a medical emergency. Administering oxygen targets the root problem of inadequate oxygenation, making it a key intervention in such situations.
