He will be perfectly OK in 5 minutes
ruleswise.
As DM would you really tell the player that his wound just disappears after 5 minutes of resting? That makes no sense. Of course the wound is still there. In those five minutes the character caught some breath, tended to his wound, put some straps around it, burnt it with a hot coal to stop the bleeding, etc.
In the next combat the wound is still there, it will be bleeding a little, the character will feel the pain, but the wound is not mechanically relevant to the game anymore, it's now just "roleplaying".
You could think "hey, but if the wound is still there, what if the character is hit again exactly on the same spot or with same gravity?" or "Shouldn't the wound somehow affect the charcater general health?" Well, somehow it still does. The character did spend some Healing Surges to heal that terrible wound. If he receives another one he maybe won't have enough HS now and it could be his last wound...
D&D characters can take more punishment than others, otherwise they wouldn't survive enough to become heroes and there would be no game right? If there was a game where common people like us could actually go into dungeons to kill monster and get out of there alive, richer and fighting even better, this game would seriously hurt my "simulationist" feelings.
