Making the almost-dead not need rising
A somewhat-underused location, the medical Cryo room found on the southern end of Medbay has two large cryotubes, a NanoMed (you'd best believe THAT gets used often, though!), various medical tools and other treatment-room gear, and its own pair of treatment rooms to the south. See Using the Cryo Chambers for detailed information on using the tubes here, but overall, you secure the gas can just outside and load in the cryoxadone beakers also just outside to make the cryo tubes do some very good healing.
There is no vent. It wouldn't be good for the sterile environment, probably.
The APC for this room is on the northeast wall.
