Not really sure what the point of the OP is. D&D is a game. It has hit points to determine whether your character dies or not.
HIt points are individual. Every player gets to decide what hit points mean to their character. When they reach 0, your character is dead (or dying). Otherwise, leave it to the player. For example, what a 6 hit point hit against a character with 26 hit points means is up to the player of that character.
One player may think 'it's just a flesh wound' and push their luck and continue fighting. Another player may consider it a damaging blow and want to retreat.
Hit points are only a gauge until your character is out of action. What they actually mean in the narrative is in the imagination of the player running the character.
