1. Air travel is not generally not a risk to normal pregnancy.
2. Fetal hemoglobin has a high affinity for oxygen, and the fetus is generally not at risk due to the low oxygen hypoxic cabin environment.
3. The American College of Obstetricians and Gynecologists does not recommend flight restrictions on women with uncomplicated pregnancies less than 36 weeks gestation, but it does recommend air travel be avoided after 36 weeks.
4. Many airlines require medical certificates for women who are pregnant beyond 36 weeks gestation.
5. Any patient in her first trimester with abdominal pain or bleeding should be evaluated and ectopic pregnancy ruled out prior to flight.
6. Any patient at risk for premature delivery (e.g. prior history, multiple gestations, cervical incompetence), with a condition that lowers placental respiratory reserve (eg, intrauterine growth retardation), or who is considered high risk (eg, preeclampsia, placenta previa) should probably not fly.
7. Obstruction of the vena cava from uterine compression and altered clotting factors combined with immobility and dehydration place the pregnant passenger at increased risk for deep vein thrombosis. She should be encouraged to ambulate every hour or two.
