How to issue a health certificate:
Older people over 70 years old should go to the hospital one week in advance to see if they are healthy and suitable for flying. Hospital physical examination focuses on ECG, respiratory tract, blood pressure and other items. Because air flight may lead to heart disease, high blood pressure and other problems for the elderly, airlines also put forward different regulations for the elderly to fly.
Old people with poor physical condition should make choices according to their physical condition or follow the doctor's advice. For example, elderly people with cardiovascular diseases are usually not suitable for flying. For the elderly with severe hypertension and heart disease, changes in atmospheric pressure may lead to increased blood pressure, decreased cardiac output, dyspnea and even life-threatening.
Due to the roar, vibration and lack of oxygen when the plane takes off and lands, patients with cerebrovascular diseases may relapse or aggravate their condition. Elderly people with respiratory diseases, otolaryngology diseases and people who have just had surgery should not fly.
