Elderly people over 80 years old can take the plane, provided that there is no hypertension, heart disease, cerebrovascular disease, bronchial asthma and other diseases, otherwise it is not recommended to take the plane. Because of the extremely thin oxygen and unstable air pressure when flying in high altitude, elderly people are very easy to form air embolism, thus causing pulmonary embolism, cerebral embolism, myocardial infarction and other serious diseases, for the elderly who suffer from cardiovascular and cerebrovascular diseases and respiratory diseases are more likely to embolism events, and it is difficult to have the corresponding rescue equipment on the plane. Therefore, elderly people with these diseases are at great risk of flying and are advised to take other means of transportation. If you must fly, you must have these chronic diseases under control in advance and carry resuscitation drugs with you before you fly.
