When undergoing surgery, one of the most critical things to understand is the risk of cardiac arrest, where the heart might stop beating. In such moments, the surgical team leaps into action, using various procedures and equipment to revive the heart quickly. From CPR to the use of defibrillators, the aim is always to restore circulation and ensure the patient's safety. Knowing what happens during such crucial moments can provide some peace of mind when facing surgery. Ultimately, it's a team's skill and preparedness that transform a heart-stopping event into a life-saving opportunity.
