In clinical practice, if the patient has a heartbeat and is not breathing, it is possible to save the patient, to perform emergency tracheal intubation, and then connect the ventilator, using the ventilator to help the patient to breathe, which is an important standard of cardiopulmonary resuscitation, an important means. Then further clarify the cause of respiratory arrest, such as cerebral origin, or infection or mechanical injury caused by respiratory arrest, need to actively treat the original cause, including reducing intracranial pressure, correcting infection, correcting electrolyte disorders, to promote the patient’s airway recovery. Medications such as naloxone hydrochloride and lorubicin can also be used to promote respiratory recovery. If cardiac arrest occurs before the recovery of spontaneous breathing, it is very unlikely that such a patient will come back.
