What maneuver is used to clear a blockage in an unconscious patient?

The Heimlich maneuver is designed to expel foreign objects blocking the airway in conscious individuals, but when dealing with an unconscious patient, this maneuver is not appropriate or effective. Instead, preventing airway obstruction relies on techniques that can effectively clear the airway while the patient is unresponsive.

The correct response to this scenario typically involves prioritizing interventions that ensure airway patency without causing additional risk to the patient. In an unconscious person, rescuers should initiate chest compressions as part of cardiopulmonary resuscitation (CPR), which not only maintains blood circulation but can also help dislodge an obstruction through the force generated in the chest.

While other options like back blows and abdominal thrusts are used for conscious patients to relieve choking, they are not advisable or effective for someone who is not responsive. Engaging in the Heimlich maneuver on an unconscious patient can increase the risk of injury or further obstruction, making it essential to focus on effective techniques like chest compressions in this context.
