SFS Standard Battle Medicine [one-action] Feat 1

Source Player Core pg. 216
Prerequisites trained in Medicine
Requirements You’re holding or wearing a medkit.
You can patch up wounds, even in combat. Attempt a Medicine check with the same DC as for Treat Wounds and restore the corresponding amount of HP; this doesn't remove the wounded condition. As with Treat Wounds, you can attempt checks against higher DCs if you have the minimum proficiency rank. The target is then immune to your Battle Medicine for 1 day. This does not make them immune to, or otherwise count as, Treat Wounds.

Traits

General:A type of feat that any character can select, regardless of ancestry and class, as long as they meet the prerequisites. You can select a feat with this trait when your class grants a general feat.
Healing:A healing effect restores a creature's body, typically by restoring Hit Points, but sometimes by removing diseases or other debilitating effects.
Manipulate:Actions with this trait require you to physically manipulate an item or make gestures to use. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
Skill:A general feat with the skill trait improves your skills and their actions or gives you new actions for a skill. A feat with this trait can be selected when a class grants a skill feat or general feat. Archetype feats with the skill trait can be selected in place of a skill feat if you have that archetype's dedication feat.
