Baby's got the bends

I'll be spending this afternoon in OB clinic, so in between patients this morning I'm reading up on the latest guidelines for prenatal care. I see that the American College of Obstetricians and Gynecologists recommends that scuba diving should be avoided during pregnancy because the fetus is at increased risk for decompression sickness. Now I'm stuck with the mental image of nine-months-pregnant women in wet suits exploring coral reefs. There's probably something wrong with me.
