Air Travel During Pregnancy ( מאתר הCDC האמריקאי-סמכות חד משמעית)
Commercial air travel poses no special risks to a healthy pregnant woman or her fetus. The lowered cabin pressures (kept at the equivalent of 1,524 to 2,438 meters [5,000 to 8,000 feet]) affect fetal oxygenation minimally because of the fetal hemoglobin dissociation curve. Severe anemia (hemoglobin, 0.5 grams per deciliter [g/dL]), sickle-cell disease or trait, a history of thrombophlebitis, or placental problems are relative contraindications to flying; however, supplemental oxygen can be ordered in advance. Each airline has policies regarding pregnancy and flying; it is always safest to check with the airline when booking reservations because some will require medical forms to be completed. Domestic travel is usually permitted until the pregnant traveler is in her 36th week of gestation, and international travel may be permitted until the 32nd week. A pregnant woman should be advised always to carry documentation stating her expected date of delivery.
An aisle seat at the bulkhead will provide the most space and comfort, but a seat over the wing in the midplane region will give the smoothest ride. A pregnant woman should be advised to walk every half hour during a smooth flight and flex and extend her ankles frequently to prevent phlebitis. The safety belt should always be fastened at the pelvic level. Fluids should be taken liberally because of the dehydrating effect of the low humidity in aircraft cabins.
