After cardiopulmonary resuscitation, due to insufficient blood perfusion and hypoxia in various organs and systems, it will inevitably cause different degrees of functional damage or reperfusion injury to tissue cells, and often lead to organ insufficiency or failure in heart, lungs, brain, liver, kidneys, and gastrointestinal tract, and even multi-organ failure. Therefore, strengthening the follow-up treatment of resuscitation, timely identification of problems, and solution of problems are particularly important for stabilizing the function of various organs and reducing the mortality rate. Specifically as follows: 1, the immediate goal of post-cardiopulmonary resuscitation treatment is to provide cardiopulmonary functional support to meet tissue perfusion, especially to the brain; 2, timely transfer of pre-hospital cardiac arrest patients to the hospital emergency department, and then to a well-equipped intensive care unit ICU, etc.; 3, timely and clear diagnosis of the possible causes of cardiac arrest; 4, improve the therapeutic measures, such as can be given to the treatment of anti-arrhythmic drugs, so as not to Arrhythmia recurrence. After cardiopulmonary resuscitation, the specific condition of the patient will change greatly, and all patients need to be carefully and repeatedly assessed for their general condition, including cardiovascular function, respiratory function and neurological function. Clinicians should identify complications of resuscitation, such as rib fractures, hemopneumothorax, pericardial tamponade, intra-abdominal organ injuries, and tracheal tube displacement.
