Medicae and multiple injuries

By Yanma, in Black Crusade

After our first session of Black Crusade I have a few questions about the Medicae skill. My character was injured to the point where he's now in the criticals thanks to a series of attacks that did minor amounts of damage. Can the Medicae skill be rolled for each injury? If not, what other ways can I quickly heal myself outside of infamy points?

At least in the other games, a single use of First Aid "caps" the wounds of the character at the new number - no further use of First Aid can ever raise the wounds above it, the rest will have to be healed with longterm care (see the Medicae talent description) or natural healing.

The paragraph about healing mentions that there are psychic powers that can aid healing, but unless I've missed one, none has been published in BC so far.
