Final answer:
To check if a victim is breathing, observe their chest, listen for breath sounds, and feel for breath. Begin CPR if breathing is absent. Use a pulse oximeter to check oxygen levels, and perform the Heimlich maneuver for choking. For drowning incidents, carry out CPR on solid ground.
Step-by-step explanation:
How to Check if a Victim is Breathing To determine if a victim is breathing, look for chest movements, listen for breathing sounds, and feel for breath on your cheek. If the victim is not breathing normally, CPR should be commenced. For a choking victim, Heimlich maneuver or back blows should be performed.
An unconscious victim may require rescue breathing or the use of a balloon device to force air into their lungs. If present, a pulse oximeter can be used to further assess the oxygen saturation level in the blood. In case of a drowning, ensure the victim is on solid ground before attempting CPR. Medical imaging may be necessary to investigate internal injuries.
