Details?: Everyone's oxygen saturation fluctuates regardless of position. When it's being tested, you must remember to keep breathing. This may sound overly simple, but people have a normal tendency hold their breath. An easy way to screen for phrenic n damage is to do a simple chest x-ray. Radiation dose is trivial. The hemidiaphragm will be elevated on the side that has damage, if present.

If I took indoethacin in my last weeks of pregnancy, should the fetal heart rate be monitored on a daily basis?

Depends: Indomethacin taken frequently over a long period of time can cause a transient change in the fetal heart circulation (in doctor speak it closes the ductus arteriosus). Small doses for only a few days, which is usually the only thing we would do, is not particularly dangerous. Check with your doctor on why you are taking it and whether monitoring is needed.
