Barotrauma Oxygen Management Calculator

Calculate oxygen generation vs consumption in your Barotrauma submarine. Configure crew, generators, and hull integrity to see your net O2 balance and time-to-critical.

Submarine Configuration

Crew Count: 4

116

Oxygen Generators: 2

Generator Condition: 100%

0%100%

Output scales linearly with condition. Repair for full efficiency.

Hull Breach

Adds O2 leakage from breach

Junction Box Power

Generators need power to run

O2 Balance

Generation Rate +3.00 mBar/s

Crew Consumption −2.00 mBar/s

Net Rate +1.00 mBar/s

Sufficient

Generators comfortably sustain your crew. O2 will stay stable.

Generators Needed

At 100% condition, you need at least 2 generators for 4 crew.

O2 Reference Values

Parameter	Value	Notes
O2 per crew member	0.5 mBar/s	Approximate resting consumption
Generator output (100%)	1.5 mBar/s	Per generator at full condition
Hull breach leakage	1.0 mBar/s	Estimated; varies by breach size
Critical O2 threshold	10 mBar	Crew takes damage below this
Room O2 maximum	100 mBar	Full atmosphere

Note: Values are based on Barotrauma community documentation. Actual in-game rates may vary slightly by submarine hull volume and mod configuration.
