The common ways to open the airway in adult CPR are jaw support method and tilting the head and lifting the jaw method. Adults need to perform chest compressions during the resuscitation process and pay attention to open the airway to ensure that the patient’s airway is open, there are two common ways to open the airway, respectively, the method of supporting the jaw and tilting the head to lift the jaw. 1. Jaw support method: it is also known as pushing up the lower jaw method, also known as two-handed jaw lifting method, which is generally applicable to patients with cervical spine injuries, or patients who may have head trauma. This method avoids the patient’s affected area from moving and helps to protect the patient’s neck and spine. 2. Tilting the head and lifting the jaw: also known as tilting the head and lifting the jaw, the patient is placed in the supine position, the doctor pushes the patient’s anterior jaw with his hand, so that the patient makes a lifting movement, one hand presses down on the frontal bone, and the other hand makes the jawbone lifting upward, so as to play the effect of opening the airway. The doctor should observe the patient’s mouth for any vomit or foreign objects, and clean it up by hand in a timely manner. If there are braces or dentures in the patient’s mouth, they should be removed in a timely manner. Opening the airway can ensure that the airway is unobstructed and can relieve the airway obstruction. Cardiopulmonary resuscitation should be carried out under the guidance of a doctor as far as possible, if there is no medical condition, while opening the airway, cardiac compression should be the main focus. Call 120 emergency at the same time.
