Is it necessary to check for a pulse before starting chest compressions in an adult?

In a situation where a patient is unresponsive, it is crucial to act quickly, particularly in cases of suspected cardiac arrest. If a healthcare provider is uncertain about whether the patient is breathing normally or has a pulse, immediate initiation of chest compressions is vital. The rationale behind this approach is grounded in the understanding that the first few seconds are critical in improving the chances of survival.

When a patient is unresponsive, not checking for a pulse can save valuable time, as starting compressions promptly can maintain blood flow to vital organs until emergency services or advanced care arrives. The BLS guidelines emphasize the importance of beginning chest compressions as soon as possible if there are signs of ineffective breathing, reflecting the need for a swift response to prevent further deterioration.

Options that involve always or conditionally checking for a pulse before beginning compressions may delay crucial interventions, which can be detrimental in a life-threatening situation.
