What is DVT?
A deep vein thrombosis (DVT) is a blood clot that develops in a deep vein, usually in a leg. This is a serious condition. Sometimes these clots can break away and travel through the blood stream to vital organs and can cause severe injury or death.
Possible Ways to Reduce the Risk of DVT
American encourages all passengers to consult with their doctors about DVT and other personal health issues before flying. Because the cause of a DVT is often not known, the best methods of preventing DVTs are still uncertain.
to try to reduce the risk of DVT, many passengers may be advised by their doctors to take the following measures in flight:
Regularly change leg position, and periodically move and stretch your legs and feet while seated. Your doctor may suggest leg exercises such as those described in the box below at regular intervals (at least every hour or so)
If conditions allow and the aisles are clear, you may want to occasionally get up and walk around. But remember that you must remain seated when the seat belt light is on and should remain in your seat with your seat belt fastened whenever possible, because of the possibility of turbulence. And all passengers are required to comply with crew member and/or FAA instructions, especially those relating to remaining seated.
Avoid crossing the legs at the ankles or knees
Stay hydrated; drink adequate nondiuretic fluids such as water, juice and milk and minimize alcohol and caffeine intake
Wear loose fitting clothing
Wear graduated compression stockings
It is possible that no measure intended to prevent DVT will be effective. It is also possible that some of the measures listed above may not be recommended for some passengers, depending on their health situations as assessed by their doctors.
