CPR

CPR (Cardio-Pulmonary Resuscitation) is an emergency procedure which purpose is to bring back a crewmember that has been rendered unconcious after sustaining major injuries or having been deprived of oxygen for too long.

Most Afflictions, such as Internal Damage or Oxygen Low will damage a Character's Vitality. When their Vitality drop to zero, they are downed, preventing any movement or actions, and the Oxygen Low affliction is added if they didn't already suffer from it. At this point, only a fellow crewmember can save them by pressing the Health key (H by default) on the downed Character to open their Health GUI, then clicking the "Perform CPR" button in the bottom right corner. Doing so will start the process, each pump slowing the progression, or even bringing down the Low Oxygen affliction if the Character performing CPR has a high enough Medical skill. Each pump also has a set chance of reviving the target.

Before starting CPR, one should make sure that the downed Character has oxygen available, either by bringing them to a room supplied with oxygen (using the Grab key, G by default), or by equipping them with a Diving Mask or Diving Suit with enough oxygen (also done by grabbing them and dropping the Mask/Suit in the appropriate slot in their inventory).

A Character's Medical skill determines how well they perform CPR.

• Stabilization chance: Skill level affects how much the oxygen level of the target rises with each pump. At level 5, the target's oxygen level will still drop, although at half speed; level 50 is the middle point, where the target's oxygen level neither drops or rises; beyond that, it will rise with each pump.
  
• Revive chance: Each pump has a chance of reviving the target (letting them regain conciousness). At level 20 and below, the chance is 5%; at level 50, the chance is 25%; at level 100, the chance is 90%.
  
• Internal Damage: Below 20, each pump will inflict Internal Damage. The lower their skill, the higher the damage, which is calculated using the following formula: 20-[medicalskill]*0.05. At level 20 and higher, no damage is inflicted.

In many situations, oxygen deprivation is not the most critical emergency; as such, when a target is bleeding out, applying Bandages or Plastiseal prior to performing CPR is necessary.
