A common way to open the airway during adult CPR is the head-up, chin-up method. The head-up, chin-up method can better open the airway, and is a more commonly used method in clinical adult CPR. The operation method is that the rescuer puts one hand on the patient’s forehead and presses down, gently tilting the head back, and the other hand is placed under the patient’s chin, gently lifting up and stretching the neck forward, so as to open the patient’s airway and clear the mouth of foreign objects. In addition, you can also choose to tilt the head to lift the neck method, or both hands to lift the jaw method, for the suspicion of neck injury, or the clear existence of the injury of the crowd, mainly using both hands to lift the jaw method. Improper exertion during CPR may lead to rib fractures, and if there is an error in the frequency of compressions, it may not be able to play an effective role in saving the patient’s life, so it is recommended that professional personnel carry out the rescue.
