Barotrauma Affliction Reference
Barotrauma's medical system is one of gaming's most complex. Search any affliction or treatment item to find what you need — fast. Covers 20+ afflictions across damage types, blood & circulation, status effects, and organ damage.

Showing 20 afflictions
Blunt Damage
Caused by
Collisions, explosions, creature attacks, pressure waves
Treatments
Threshold: Surgery required if intensity > 80
Note: High blunt damage causes unconsciousness. Morphine reduces pain penalty; Stabilozine accelerates healing.
Lacerations
Caused by
Sharp creature attacks, debris, shrapnel
Treatments
Threshold: Surgery required if intensity > 90
Note: Lacerations can become infected if untreated. Apply Antibiotics promptly after any infected laceration.
Burn Damage
Caused by
Fire, electrical arcs, welding accidents, reactor exposure
Treatments
Threshold: Surgery required if intensity > 80
Note: Burns deal continuous damage until treated. The Burn Treatment Kit is significantly more effective than a plain Bandage.
Gunshot Wound
Caused by
Firearms, coilguns, rail weapons
Treatments
Threshold: Surgery required if intensity > 60
Note: Gunshots cause rapid bleeding on top of the wound itself. Apply a Bandage first to stop bleeding, then Morphine for pain.
Bite Wounds
Caused by
Mudraptor bites, Spineling attacks, Hammerhead bites
Treatments
Threshold: Infection sets in if Antibiotics not applied within ~5 seconds of the bite
Note: Bite wounds carry a high infection risk. Always carry Antibiotics on your hotbar when fighting creatures.
Bleeding
Caused by
Lacerations, gunshots, bite wounds, sharp impacts
Treatments
Threshold: Fatal if intensity reaches 100
Note: Tourniquets only work on arms and legs. Hemostat stops bleeding instantly but reduces max blood. Bleeding stacks with other wounds.
Cardiac Arrest
Caused by
O2 < 5%, extreme damage, very low blood volume
Treatments
Threshold: Death in ~30 seconds without intervention
Note: CPR alone is rarely sufficient. Epinephrine is the fastest fix if applied within 10 seconds. After 10 seconds, switch to a defibrillator.
Low Blood Volume
Caused by
Excessive bleeding, blood-draining afflictions
Treatments
Threshold: Unconsciousness below 20% blood volume
Note: Saline Bag is faster at restoring blood volume. Blood Pack restores slightly more total blood. Do NOT give sugar — it does not help.
Hypoxemia
Caused by
O2 below 10%, smoke inhalation, no oxygen supply
Treatments
Threshold: Cardiac arrest risk rises sharply below 5% O2
Note: Equip an oxygen tank in the gear slot to prevent Hypoxemia in flooded or smoke-filled areas. Oxandrolone helps when O2 supply is limited.
Internal Bleeding
Caused by
High blunt/explosive damage, organ damage compounding
Treatments
Threshold: Surgery required — cannot be fully treated without it
Note: Internal bleeding cannot be stopped with bandages. Stasis Bag buys time for surgery prep. This is a medical emergency.
Psychosis
Caused by
Combined organ damage exceeding 70, prolonged stress
Treatments
Threshold: Hallucinations and erratic behavior begin at moderate intensity
Note: Psychosis causes the player to see false signals, monsters, and flooding. Treat underlying organ damage to prevent recurrence.
Husk Infection
Caused by
Husk creature attacks, infected bite wounds
Treatments
Threshold: Irreversible at Stage 3 — character becomes a Husk
Note: Calyxanide must be applied before the infection reaches Stage 3. There is no medical cure at Stage 3 — the character dies and revives as a Husk.
Paralysis
Caused by
Spine damage, electric shock, certain creature toxins
Treatments
Threshold: Full paralysis renders the character unable to move
Note: There is no direct cure — paralysis must run its course. Fentanyl manages pain but does not accelerate recovery. Protect paralyzed crewmates.
Nausea
Caused by
Consuming alien spores, spoiled food, parasite exposure
Treatments
Threshold: Vomiting at moderate intensity reduces movement speed
Note: Nausea impairs movement and can be debilitating in combat. Check food sources — do not eat alien flora without proper preparation.
Unconsciousness
Caused by
Severe damage, low blood volume, O2 deprivation, overdose
Treatments
Threshold: Character cannot act until revived
Note: Epinephrine revives an unconscious character quickly but may mask underlying causes. Always treat the root affliction after revival.
Pressure Damage
Caused by
Diving without a pressure-resistant suit in deep water
Treatments
Threshold: Instant death above intensity 100
Note: Wear a Diving Suit or Rebreather in the ocean. Pressure damage is instant and fatal — there is no item to cure it once taken.
Radiation Sickness
Caused by
Extended reactor exposure, radioactive zones
Treatments
Threshold: Radiation sickness begins accumulating at exposure > 50
Note: Potassium Iodide must be taken before exposure to prevent sickness. Once radiation sickness is at high intensity, there is no direct reversal — only slow natural recovery.
Liver Damage
Caused by
Alcohol consumption, chemical exposure, certain toxins
Treatments
Threshold: Reduces alcohol tolerance; high intensity causes bleeding compound
Note: Liver damage reduces the body's ability to metabolize toxins and drugs. Avoid alcohol when liver damage is present — it accelerates the affliction.
Kidney Damage
Caused by
Chemical toxicity, dehydration, compound organ failure
Treatments
Threshold: Causes additional bleeding damage at moderate intensity
Note: Kidney damage compounds other blood-related afflictions by reducing the body's ability to regulate fluids. Treat quickly to prevent cascading effects.
Heart Damage
Caused by
Electric shock, high blunt damage, cardiac arrest aftereffects
Treatments
Threshold: Increases cardiac arrest risk at moderate intensity
Note: Heart damage is particularly dangerous as it raises the risk of cardiac arrest under stress. Treat as a priority whenever it appears.
How Barotrauma's medical system works
Intensity & Thresholds
Each affliction has an intensity value from 0–100. Crossing certain thresholds triggers new symptoms, unconsciousness, or death. Surgery is required when some afflictions exceed their surgery threshold.
Treatment timing
Many treatments must be applied quickly — Epinephrine for cardiac arrest within 10 seconds, Antibiotics for bite wounds within 5 seconds. Delay can result in permanent organ damage or death.
Surgery
High-intensity wounds require surgery at a medical fabricator. The patient must be anesthetized (Anesthetics item). The surgeon's Medicine skill determines success rate and complications.
