What should you do if a diver is experiencing an air embolism?

When a diver is experiencing an air embolism, it is crucial to respond quickly and effectively to minimize potential damage. Administering oxygen and seeking emergency medical assistance is essential because high-flow oxygen can help alleviate symptoms and prevent further complications by reducing the size of the bubbles in the bloodstream.

Air embolism occurs when air enters the bloodstream, often due to improperly ascending or holding breath during ascent. The symptoms can vary from mild to life-threatening, so immediate action is required. Oxygen helps improve tissue oxygenation and supports the body while transporting the diver to a medical facility.

It is important to recognize that ignoring the symptoms and continuing the dive could lead to worsening conditions, as would waiting for the diver to stabilize on their own. Furthermore, performing CPR required in cases of cardiac arrest should be done alongside oxygen administration, not as a standalone response, as oxygen is vital for effective resuscitation efforts if needed.
