It happens from time to time that people around you suddenly faint. Most fainting is caused by temporary ischemia of brain tissue due to impaired circulation. It is important to take some relevant first aid measures. The following is an introduction to the first aid measures after fainting, I hope it will be helpful to you. How to give first aid when someone around you faints For the first aid of this situation, you should first distinguish what kind of cause it belongs to. Different situations should take different first aid measures. In general, when someone faints, first find out if the patient is conscious, call him to see if there is a reaction; feel for a pulse; see if there is breathing; whether there are convulsions, sweating, incontinence. If an ambulance comes, take an emergency blood pressure, listen to the heartbeat, and feel for aortic pulsation. The two most common types of syncope are cardiogenic and neurogenic. First aid for cardiogenic syncope Cardiogenic syncope is caused by abnormal heart function and a sudden decrease in cardiac blood output. Cardiogenic syncope often develops suddenly, some lasting for a few seconds, and some lasting longer. If the patient wakes up after a short period of time, he or she should immediately consult a doctor, and if the longer the time, the more dangerous the condition is, and the more time should be spent on resuscitation, otherwise there is a risk of death. First aid should be used boxing anterior chest area or extrathoracic cardiac compression. And quickly escort the patient to the hospital rescue. Second, the first aid of vascular neurosyncope Vascular neurosyncope is mostly due to pain, mental tension, fear, anxiety, fatigue, sadness, anger and hot climate, etc., so that the patient’s whole body small blood vessels dilate, resulting in a drop in blood pressure and cerebral ischemia. Patients have premonitory signs before fainting, such as feeling weak, stuffy, panic, dizziness, dizziness, and then suddenly fainting. For this type of fainting patients, they should be quickly laid down and keep their head low and feet high position to improve the blood supply to the brain. And untie the patient’s collar and belt, etc., so that they keep breathing will usually improve, if it does not improve should immediately seek medical attention.
