Showing 20 afflictions

💥

Blunt Damage

Damage
MinorModerateCritical

Caused by

Collisions, explosions, creature attacks, pressure waves

Treatments

💉 Morphine💊 Stabilozine

Threshold: Surgery required if intensity > 80

Note: High blunt damage causes unconsciousness. Morphine reduces pain penalty; Stabilozine accelerates healing.

💥

Lacerations

Damage
MinorModerateCritical

Caused by

Sharp creature attacks, debris, shrapnel

Treatments

🩹 Bandage (stops bleeding)💊 Antibiotics (if infected)🔧 Surgery

Threshold: Surgery required if intensity > 90

Note: Lacerations can become infected if untreated. Apply Antibiotics promptly after any infected laceration.

💥

Burn Damage

Damage
MinorModerateCritical

Caused by

Fire, electrical arcs, welding accidents, reactor exposure

Treatments

🧴 Burn Treatment Kit🩹 Bandage

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

Damage
ModerateCritical

Caused by

Firearms, coilguns, rail weapons

Treatments

🩹 Bandage💉 Morphine💊 Calomel

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

Damage
MinorModerateCritical

Caused by

Mudraptor bites, Spineling attacks, Hammerhead bites

Treatments

💊 Antibiotics (within 5 seconds)🩹 Bandage

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

Blood
MinorModerateCritical

Caused by

Lacerations, gunshots, bite wounds, sharp impacts

Treatments

🩹 Bandage🩹 Tourniquet (limbs only)💉 Hemostat

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

Blood
Critical

Caused by

O2 < 5%, extreme damage, very low blood volume

Treatments

❤️ CPR (chest compressions)💉 Epinephrine (within 10s)⚡ Defibrillator (after 10s)

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

Blood
MinorModerateCritical

Caused by

Excessive bleeding, blood-draining afflictions

Treatments

🩸 Saline Bag (1.5× blood restoration)🩸 Blood Pack

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

Blood
ModerateCritical

Caused by

O2 below 10%, smoke inhalation, no oxygen supply

Treatments

🫁 Oxygen Tank💊 Oxandrolone

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

Blood
ModerateCritical

Caused by

High blunt/explosive damage, organ damage compounding

Treatments

🧊 Stasis Bag (stabilizes for surgery)🔧 Surgery required💉 Morphine (pain management)

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

Status
ModerateCritical

Caused by

Combined organ damage exceeding 70, prolonged stress

Treatments

💊 Haloperidol

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

Status
MinorModerateCritical

Caused by

Husk creature attacks, infected bite wounds

Treatments

💊 Calyxanide (effective before Stage 3)

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

Status
ModerateCritical

Caused by

Spine damage, electric shock, certain creature toxins

Treatments

⏳ Wait (wears off over time)💉 Fentanyl (pain management)

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

Status
MinorModerate

Caused by

Consuming alien spores, spoiled food, parasite exposure

Treatments

💊 Antiparasitic

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

Status
Critical

Caused by

Severe damage, low blood volume, O2 deprivation, overdose

Treatments

🧪 Smelling Salts💉 Epinephrine

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

Status
Critical

Caused by

Diving without a pressure-resistant suit in deep water

Treatments

🚫 No treatment — prevention only

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

Status
MinorModerateCritical

Caused by

Extended reactor exposure, radioactive zones

Treatments

💊 Potassium Iodide (prevents accumulation — not a cure)

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

Organ
MinorModerateCritical

Caused by

Alcohol consumption, chemical exposure, certain toxins

Treatments

💊 Liver Support

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

Organ
MinorModerateCritical

Caused by

Chemical toxicity, dehydration, compound organ failure

Treatments

💊 Kidney Support

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

Organ
MinorModerateCritical

Caused by

Electric shock, high blunt damage, cardiac arrest aftereffects

Treatments

💊 Cardiac Stimulants

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.
