Cardiac arrest

Cardiac arrest refers to the sudden termination of the ejection function of the heart, the disappearance of aortic pulses and heart sounds, and severe organ ischemia and hypoxia, leading to the termination of life. This unexpected sudden death is also called sudden death in medicine. Ventricular fibrillation is the most common cause of cardiac arrest. If the patient is called for no response, and there is no response in the supraorbital and suborbital pressures, it can be determined that the patient is in a coma. Pay attention to observe the patient's chest and abdomen for undulating breathing movements. If there is no pulsation in the carotid and femoral arteries, and no heartbeat can be heard in the precardiac area, it can be determined that the patient has a cardiac arrest.
