We've been watching a data dance between the top graph line of the heartbeat, and the bottom graph line showing the contractions. In the first photo, the heartbeat was dropping too low during contractions, so they turned off the inducing drug and put Amy on oxygen (mom gets more air, so does baby). The team believes that since the baby is still high up in the pelvis, the contractions are causing the umbilical cord to kink in a way that affects the heartbeat. So the nurse has set up another IV to pump amniotic fluid back into the uterus, which has been drying out since the original water broke and drained. This is all such a wet process! As you can see in the last frame, within minutes of pumping the fluid back in, the kid's heart rate stabilized against the contractions. The bathtub's comfy again.
