My hospital required CFM, but they had telemetry monitors, which was awesome. I was able to make a million laps around the floor, go in the tub/shower, etc.
They did only have a limited amount, but they saved those for the moms laboring without an epi. I did end up getting an epi, and they switched me to a wired one. At that point, I was happy to give it up in hopes that another mom could use it and walk around.
