What kind of person can't fly?

People with hypertension, cerebrovascular diseases and digestive system diseases can't fly.

1, cardiovascular patients

Hypertension patients have high blood pressure 180 mm Hg or above, and low blood pressure 130 mm Hg or above. Within one month after severe heart failure and myocarditis; Within 30 days, angina pectoris occurred frequently and severe arrhythmia occurred; Within two weeks of cerebrovascular accident; Myocardial infarction has occurred within 6 weeks, and it is not suitable for flying with or without complications.

For patients after heart surgery, even short-distance flight within 3 weeks after operation is not appropriate, because the tension of flight and high altitude hypoxia may increase the heart load. ?

2. Patients with cerebrovascular diseases

Craniocerebral injury, skull fracture with coma or irregular breathing rhythm; Within 30 days of brain inflammation, tumor or brain hernia surgery; Patients with cerebral embolism, cerebral hemorrhage, brain tumor and intracranial aneurysm are theoretically not suitable for flying. Patients with cerebral embolism have to wait at least 3 weeks before they can fly. ?

3. Patients with digestive system diseases

Patients with upper gastrointestinal bleeding, acute appendicitis, peptic ulcer with deep ulcer surface and gastrointestinal bleeding have stopped bleeding for less than 3 weeks, so it is best not to fly. Patients who have undergone gastrointestinal surgery can only fly more than 10 days after operation to avoid high-altitude gas inflation, which will lead to gastrointestinal rupture. ?

4. Several types of postoperative patients

/kloc-Head surgery, ophthalmology surgery, otorhinolaryngology surgery and gastrointestinal surgery within 0/5 days; Less than 48 hours after thoracoabdominal surgery; Because of encephalitis, tumor, brain hernia, less than 30 days before operation, it is best for the above patients not to fly, so as to avoid the pressure change on the way, tear the closed wound again, and the blood vessels in the operation area bleed.

5, severe anemia

Because the partial pressure of inhaled oxygen decreases at high altitude, human tissues are prone to hypoxia. According to the contraindications of air travel drawn up by the American Aerospace Medical Association, patients with hemoglobin below 6 g/dl are strictly prohibited from flying without strict medical supervision. ?

6. People with upper respiratory tract infection and some nasal diseases.

The patient's nasal cavity is not smooth and the sinus ostium is often blocked. Generally speaking, patients with the following diseases are not recommended to fly. It is best to wait until the critical period or choose other modes of travel such as high-speed rail. The air pressure balance inside and outside the sinus can be adjusted in time, and patients will feel pain in the sinus area.

In patients with upper respiratory tract inflammation, the mucosa around the pharyngeal orifice of eustachian tube is swollen, and it is difficult to open the eustachian tube. When the plane goes up or down, it can't make the air circulate, which will cause severe pain and damage the middle ear and sinuses. In addition, patients with severe cold should prepare some drugs such as nasal passages, such as ephedrine and other vasoconstrictors before flying. ?

7. Passengers who are drunk or poisoned by narcotics and other drugs are not suitable for flying. ?

8. Orthopedic patients

Fracture passengers (plaster fixation, etc. ), artificial limbs (driven by carbon dioxide cylinders) and acute paralysis are not suitable for flying.

9. Pregnant women with habitual abortion or premature delivery tendency should not fly for a long time.

Abortion in the first trimester is relatively easy, so it is not appropriate to take the opportunity. /kloc-those who are pregnant within 0/2 to 32 weeks can take this flight, and they need to bring a diagnosis certificate when taking this flight. People who are pregnant for more than 32 weeks should not fly because air travel may lead to premature birth. It is even more unsuitable to fly near the due date.

Extended data

If you suffer from chronic diseases or acute diseases such as bad cold and acute gastroenteritis recently, it is best to consult medical staff before flying, take necessary drugs according to the requirements of medical staff, and master basic medical knowledge.

Especially for patients with cardiovascular and cerebrovascular diseases, first-aid drugs should be prepared when boarding the plane, and it is best to bring sphygmomanometer, thermometer and other instruments to detect vital signs at any time. Don't fly when you are tired.

When buying a plane ticket, you might as well choose a big plane. When the air pressure changes greatly during takeoff and landing, you can move your chin more, chew and swallow, which can adjust the air pressure changes in your body and avoid excessive visceral pressure. ?

Drink plenty of water during the flight, stand up and stretch your upper and lower limbs every 30 minutes, or leave your seat to promote blood circulation. If you suddenly feel chest tightness, asthma and other discomfort in the air, you should ask the flight attendants for help in time to buy time for treatment.
