In a medical emergency within a dental office, the administration of oxygen is essential, particularly in situations where a patient may experience respiratory distress, syncope, or other forms of unconsciousness. Oxygen acts to quickly restore adequate oxygen levels in the bloodstream, which can be critical for ensuring the patient’s safety and facilitating recovery.

Oxygen supports the body’s vital functions and is often the first-line intervention in emergencies, ensuring that the tissues and organs receive the necessary oxygenation. It can be administered easily and has immediate effects, which makes it indispensable during medical crises.
