In case of an emergency scenario in which an individual is not breathing and has no pulse, timely delivery of CPR can make a difference between life and death. The main objective of CPR is to keep the oxygenated blood pumping to the brain and vital organs in order to keep the individual alive until the medical team arrives. If the individual is in a confined space, the technique called as over-the-head CPR is required in order to properly compress the chest. If there are two rescuers available, the straddle CPR can be utilized if lateral CPR is not possible.
If you are the only rescuer, you have to perform the over-the-head CPR. Initially, you have to check the victim if he/she is conscious by patting on the shoulder or asking in a loud voice “Are you okay?” If the individual does not respond, call for emergency assistance before starting CPR. You have to turn the victim on his/her back and position yourself at the head of the individual, with the knee touching the shoulders. The head must be tilted back to open the airway. Feel if breathing is present with your cheek while checking if the chest rises.
Place the mask over the nose and mouth, creating a seal by firmly holding it against the skin using your thumb and index finger on the mask. The remaining three fingers will hook on the side of the jaw. Pull up on the jaw to open the airway and squeeze the bag with your free hand to deliver a breath. Once the chest rises, deliver another breath.
The heel of one hand is placed in the center of the chest in between the nipples. Position the other hand on top of the first hand. You have to lean forward and position your shoulders directly above the hands with elbows locked.
Using your upper body weight, compress the chest 2 inches during each compression. The compression must be done rapidly at the rate of 100 per minute. Stop after 30 compression and repeat until signs of life are present.
If there are two rescuers, straddle CPR can be performed. This technique follows the same principles as the over-the-head CPR. Initially, the first rescuer is in the same position as with the over-the-head CPR while the second rescuer straddles across the abdomen of the victim, facing the head.
The first rescuer checks for breathing and a pulse. If the signs are absent, the chin-lift maneuver is performed and delivers two breaths. The second rescuer performs 30 compressions while allowing the first rescuer to perform two more breaths.
Five cycles must be repeated and then switch position to allow the second rescuer to rest. Continue to perform CPR until there are signs of life or an AED is available or when the medical team arrives on the scene.
