Scripted morphium ?

[mimin]

Hi,

I'm making a mission. Looks some like this:
You have group of soldiers, but there's a hero. When he reach 0 health, he is... stunnned ?? reviveable by morphine. (I did this by setting personage in ables). If all squad dies, the mission fails. But if anyone survived, the map change clip and it continues even if the hero is "stunned". How can i revive him through scripts ? Is it even possible ?
