How do female doctoral students in Qingdao treat elderly people with coma and cardiac arrest on the roadside?
The doctor of medicine laid the old man flat on the road with everyone and gave him cardiopulmonary resuscitation. With the professional assistance of the woman, the old man gradually recovered his spontaneous breathing, and passers-by also called 120 emergency number. 120 arrived at the scene, and the woman left the scene silently.

Cause of cardiac arrest. Cardiac arrest can seriously threaten people's lives. There are two causes of cardiac arrest, cardiogenic and non-cardiogenic. The relatively simple understanding of cardiogenic factors is that the heart itself suffers from some kind of disease, and cardiac arrest will occur under certain conditions. The other is a non-cardiogenic factor, which is simply understood as the recurrence of diseases other than the heart, such as cerebral hemorrhage; Food poisoning or drug poisoning can also cause cardiac arrest.

Rescue time of cardiac arrest. Of course, the earlier the rescue time after cardiac arrest, the better. As time goes on, the chances of patients being cured will be lower and lower. The rescue time after cardiac arrest should not be less than 10 minute. The heart is the blood supply organ of the human body, which will cause hypoxia in the body tissue for a long time. The damage caused by hypoxia is irreversible and will do great harm to human body. After more than ten minutes, the brain will basically announce that there is damage, resulting in memory and brain activity not as good as before, and there is a risk of causing a vegetative state. Early identification of cardiac arrest and rapid cardiopulmonary resuscitation are very important.

The rescue process of cardiac arrest. The rescue process of cardiac arrest is actually not complicated. If the patient has this situation, it is necessary to judge whether the patient's consciousness exists. First, the patient will lie flat on the ground, put his hands on his sides and keep his body upright. And untie the belt and coat, and then press your chest with your hands crossed. The pressing frequency is about 100 times per minute, and the pressing depth is about 5 cm. Pressing for twenty seconds requires artificial respiration of the patient. After doing it five times in a row, observe whether the patient is conscious and whether he can recover his spontaneous breathing ability. When the patient's face turns rosy, it proves success.
