What should be done immediately if a patient is unresponsive?

The immediate action taken when a patient is unresponsive is to check for airway patency and initiate rescue breathing if necessary. This is critical because an unresponsive patient may be unable to maintain an open airway, which compromises oxygen delivery to the lungs and ultimately affects oxygenation of vital organs.

In this situation, assessing and ensuring that the airway is clear can prevent potential respiratory failure. If the individual is not breathing or is only gasping, initiating rescue breathing can provide supplemental oxygen until emergency medical help arrives. Recognizing and addressing the airway as the priority helps set the foundation for further interventions, such as CPR if there are no signs of circulation.

While checking vital signs, applying CPR, administering first aid, or calling for help are also important steps, they should come after ensuring that the airway is secure. This approach aligns with the priorities in emergency care, emphasizing that maintaining oxygenation and airway access is paramount when dealing with an unresponsive individual.
