More than half of heart accidents die within half an hour after onset. Practice has proved that cough, as a rapid, effective and simple CPR, can save the lives of many patients and win extremely valuable time for future treatment. Therefore, mastering this simple and effective first aid method can win treatment time for patients to a great extent.
(1) Prevention of orthostatic syncope: Poor cardiovascular regulation and compliance in patients with cardiovascular diseases. After lying in bed or squatting for a long time, due to insufficient blood pressure regulation, postural hypotension is caused, which in turn induces cerebral ischemia and is prone to syncope. In order to prevent accidents, when standing up or squatting, you can prevent syncope by holding your breath and coughing a few times.
As long as it is an effective cough, it can squeeze the pulmonary circulation, make blood flow into the heart, and accelerate contraction through "shock". During contraction, blood pressure can rise by 50mmHg, which can improve the blood supply to the brain. This is not only a precaution, but also a timely help, which can effectively prevent syncope and fall, especially for people who have had similar symptoms. You may wish to use this method.
(2) Prevention of sudden cardiac death: Most patients with sudden cardiac death are ill-fated and difficult to recover. In this extremely short time, patients are often unable to call for help or help. The most feasible, effective and quickest way is to cough loudly.
Cough can generate about 75J of dynamic energy, and then it can be converted into bioelectric current, which can give the dying heart a chance of resuscitation like "defibrillation", and its effect is similar to beating resuscitation.
Patients with cardiovascular diseases should first be calm when encountering accidents. They can bring their own emergency medicine, ask their families and neighbors for help, and call 120 emergency number in time.
