Examine your teammate:
Your teammate can assist by checking their health status and informing you if the border of the bleeding or organ symbol is red or yellow. Prioritize fixing red-bordered elements to expedite their recovery. If they have significant blood loss and organ damage, address the bleeding first. Blood transfusion should be the last step.
Medical supplies must be in your chest rig or pockets; they cannot be stored in your safe container when you want to aid your teammates.
Depending on the severity of the damage, teammates may either die instantly or fall into a coma. When in a coma, you can revive them using your healing tools.
You cannot heal your teammates if the brain or heart is damaged hard.
If secondary organs like the lungs or liver are damaged, the player falls into a coma, and you can use the survival kit to revive them. This must occur before the timeout.
Broken bones transition in a gradient from yellow to red on your character's health panel. The darker it gets, the more maximum stamina you lose. You can repair them by using a splint.
Arm fractures will lower your aiming ability, and leg fractures will reduce your running speed.
Expensive first aid items can be stashed in your safe container. You can even save some space by using a QRKit or an M-Fac Kit, which provide additional stash slots. Items that should go into your safe container are the blood bags and surgical kits, while bandages can be stored in your pockets.
