Final answer:
To assist a choking victim that is too large to perform the Heimlich maneuver normally, encourage coughing and attempt back slaps; if unsuccessful, use alternate Heimlich techniques like chest thrusts or pressing on the sternum. Emergency care should be called immediately if the victim is not getting oxygen. CPR should only be performed by those properly trained.
Step-by-step explanation:
When assisting a choking victim who is too large to wrap arms around for the Heimlich maneuver, alternative methods must be employed. If the individual is standing, you should still encourage the person to cough to dislodge the object. If that is not sufficient, give them a few hard back slaps to help force the lodged object out of the airway. If back slaps don't work, you can try the Heimlich maneuver by standing to one side and reaching your arms around as far as possible, or by pressing upward on the lower part of the sternum with the heel of your hand. In critical scenarios where normal methods are not possible due to the victim's size or if the victim is in a seated position, you can perform chest thrusts from behind, aiming to use a quick upward thrust to force the lungs to expel air and dislodge the object.
If these techniques do not work and the person becomes unconscious, or if there are signs that the person is not getting enough oxygen, such as turning blue or inability to breathe or speak, call for emergency medical care immediately. It's also vital to note that CPR should only be performed if properly trained, due to the potential for serious injury, and chest compressions should be done with proper technique to minimize risks.
