How Does CPR Differ for an Unresponsive Adult Choking Victim?

When an adult becomes unresponsive while choking, immediate intervention is crucial. This means the individual is no longer conscious and cannot actively help clear their airway, which is blocked by a foreign object. This emergency requires a modified approach to cardiopulmonary resuscitation (CPR) to address the obstruction and maintain vital functions. Standard CPR techniques are adapted to dislodge the foreign body while also providing circulatory and respiratory support.

Identifying Unresponsiveness in a Choking Emergency

Recognizing unresponsiveness in a choking victim is the first step. If an adult who was choking collapses, check for responsiveness by gently tapping their shoulder and shouting. Simultaneously, observe for any signs of normal breathing. If the person does not respond or is only gasping, they are unresponsive due to airway obstruction.

Upon confirming unresponsiveness, act immediately. If you are alone, call 911 or your local emergency number. If another person is present, instruct them to call for help while you begin interventions. Lower the person to a firm, flat surface, ensuring their back is flat. This positioning allows for effective chest compressions and facilitates airway management.

CPR Modifications for Unresponsive Choking

When a choking victim becomes unresponsive, the standard CPR sequence is modified to prioritize clearing the airway obstruction. The primary goal of these modifications is to dislodge the foreign object while providing oxygen and maintaining blood circulation. This integrated approach combines chest compressions with airway checks and rescue breaths.

Chest compressions are the initial and most forceful intervention. Place the heel of one hand on the center of the person’s chest, specifically on the lower half of the breastbone, and interlock your fingers. Deliver compressions at a rate of 100 to 120 per minute, pushing down 2 to 2.4 inches (5-6 cm). These compressions generate pressure, which can create an artificial cough to dislodge the object and circulate oxygenated blood.

After 30 chest compressions, the next step involves checking the airway. Open the person’s mouth using a head-tilt, chin-lift maneuver, which helps to open the airway. Look inside for the foreign object. If you can clearly see the object and it appears loose or graspable, carefully remove it with your fingers. It is important to emphasize that you should never perform a blind finger sweep, as this risks pushing the obstruction further into the airway.

Following the airway check, give two rescue breaths. Pinch the person’s nose shut and create a complete seal over their mouth. Deliver each breath over one second, observing if the chest rises. If the first breath does not cause the chest to rise, reposition the head by performing the head-tilt, chin-lift maneuver again, and then attempt the second breath. If neither breath goes in or the chest does not visibly rise, it indicates the airway remains blocked. Immediately return to chest compressions without attempting further breaths.

Continue the cycle of 30 chest compressions, an airway check, and up to two rescue breaths. This continuous loop ensures ongoing efforts to clear the obstruction and provide oxygenation until the object is dislodged, the person shows signs of life, or emergency medical services arrive.

Post-Obstruction Care and Continued Action

Once the obstruction is cleared, assess the person’s condition. If they begin to breathe normally or regain consciousness, discontinue CPR. Medical attention remains necessary to assess for potential injuries from the choking episode or resuscitation.

If the person remains unresponsive but is breathing normally after the obstruction is cleared, place them in a recovery position. This involves rolling them onto their side, which helps keep the airway open and prevents aspiration. Continue to monitor their breathing and responsiveness closely until emergency medical personnel arrive. If the foreign object is not cleared and the person remains unresponsive and not breathing normally, continue the modified CPR sequence without interruption. This continuous cycle of compressions, airway checks, and breaths should persist until professional medical help arrives or they show signs of recovery.
