Cryo is fantastic, I use it all the time. It's way better for healing off someone's wounds than wasting Medbay's finite chems (especially when it comes to TOX damage, which is a horrible waste of charcoal to treat otherwise), and the fire-and-forget nature is excellent for triage. It allows you to spend your time focusing on treating syndromes and conditions rather than patching up residual damage on people whose condition is serious but not critical.
