Auxiliary medical equipment for cardiac arrest

Qingdao subway staff use AED to rescue passengers with cardiac arrest, so what is the principle of AED rescue? Simply put, it is ventricular defibrillation. Then the next step is ventricular fibrillation, which is a fatal, irregular and ineffective ventricular contraction and belongs to arrhythmia. When ventricular fibrillation occurs, the patient will face the threat of death.

The patient developed ventricular fibrillation during the onset. If not treated in time, the heart will lose its ability to transport blood because of the loss of contractility, resulting in insufficient nutrition of brain tissue and permanent death of brain cells. Once human brain cells die, death is irreversible. AED rescue is a strong electric shock with AED instrument after the patient has ventricular fibrillation, so that the patient's heart gradually returns to normal. According to valid data, the rescue rate of AED for cardiopulmonary resuscitation is much higher than that of normal waiting for ambulance rescue and conventional cardiopulmonary resuscitation.

Heart disease has become the first killer threatening health, and there are countless cardiac arrests caused by heart disease every year. Many stars we know also ended their lives because of cardiac arrest, so how to effectively prevent the harm of heart disease to human beings has become the most important thing in people's daily life in terms of health. So, how should we ordinary people prevent heart disease? The simplest and most effective way is to actively exercise and enhance physical fitness. For example, do some jogging, play badminton and table tennis, and climb a mountain properly when the weather is good to increase the contractility of the heart. When the contractility of the heart is enhanced, the blood flow rate in the body will be accelerated, and the cellular nutrients in the body will increase, which is beneficial to our metabolism. Moreover, when the blood flow rate is accelerated, it will also impact the fat particles on the blood vessel wall, making the blood vessel wall clean, which is very beneficial to prevent cardiovascular and cerebrovascular diseases.

AED equipment is the embodiment of modern scientific and technological progress and the crystallization of human wisdom. The emergence of AED rescue will certainly play a great role in the rescue of heart patients under certain circumstances such as on-site illness. Although the rescue equipment is advanced, it is still necessary to give priority to physical exercise, pay attention to the usual diet and reduce the occurrence of heart disease.
