Condition to check unit damage

[FunnyCookieEver 1]

Hi, was wondering how to check unit for ACE damage specifically, not for vanilla damage, it doesn't work.

There is info everywhere on how to add damage to unit (ace_medical_engine_fnc_damageBodyPart) etc. but not on how to get it.

 

https://github.com/acemod/ACE3/blob/master/addons/medical_engine/functions/fnc_handleDamage.sqf searched here for info, but no luck.

As I understand this stuff is stored in those:
_unit getVariable [QGVAR($HitLeftArm), [0,0]];
_unit getVariable [QGVAR($HitRightArm), [0,0]];
_unit getVariable [QGVAR($HitLeftLeg), [0,0]];
_unit getVariable [QGVAR($HitRightLeg), [0,0]]

_unit getVariable [QGVAR($HitPelvis), [0,0]],
_unit getVariable [QGVAR($HitAbdomen), [0,0]],
_unit getVariable [QGVAR($HitDiaphragm), [0,0]],
_unit getVariable [QGVAR($HitChest), [0,0]]

But I have no clue how to get data from those to check if player has healed the unit.
In my case I'm making generated task to heal a unit, but how to check if if the unit was succesfully healed?
