Healing and Initiative Passes, A Newby Nooberson question Options

[ilikesanta]

In the rules it says that "first aid takes a complex action, and Takes a number of Combat Turns equal to the amount of damage the character is attempting to heal." So what happens if the healer has multiple Initiative Passes? Is it like driving, where as long as the healer spends one action healing she can say shoot at people during her other combat passes? Is the Healer reduced to only one combat pass, because healing takes up so much energy? Or am I reading this wrong, and a healer with three Initiative Passes heal all three Passes within a single combat round?

Along the same lines, the person being healed can still do stuff within reason, like shoot guns or jump in the matrix, right?

Thanks
