What should be done if a patient is unresponsive and not breathing?

Starting CPR immediately is critical when a patient is unresponsive and not breathing because this intervention is essential for preserving brain function and circulation until more advanced medical help arrives. The first few minutes following cardiac arrest are crucial; without oxygenated blood circulating to the brain and other vital organs, irreversible damage can occur rapidly.

Initiating CPR helps maintain some blood flow and can increase the chance of survival significantly. It involves chest compressions to circulate blood and rescue breaths to provide oxygen. The immediate action is preferred over any delay, as the effectiveness of CPR diminishes over time if not started right away.

In scenarios where a patient is unresponsive and not breathing, the emphasis is on taking swift action—beginning CPR can be the difference between life and death for the individual.
