After achieving return of spontaneous circulation (ROSC) in a patient, which action should be taken next?

After achieving return of spontaneous circulation (ROSC), it is crucial to check for the patient's breathing and pulse. This step ensures that the patient is stable and that the heart is effectively pumping blood and that air is reaching the lungs. Checking for these vital signs allows health care providers to assess whether additional interventions are necessary, such as assisting with breathing or initiating further medical treatment if the patient is not breathing adequately or is pulseless.

Continuing CPR without checking for vital signs would be inappropriate because it could undermine the patient's recovery efforts after ROSC. Transferring the patient to a higher care facility immediately might be premature without first confirming stability through the vital signs assessment. Waiting for further instructions from bystanders is also not prudent, as immediate evaluation of the patient's condition is essential for appropriate and timely care.
