Oxygen

This article is about Game Mechanic. For The affliction, see Oxygen Low.

Oxygen is a mechanic. A few Creatures, like Humans, require Oxygen to breathe. Oxygen breathers that do not get enough Oxygen will suffocate and experience Oxygen Low , leading to unconsciousness and eventually death.

Mechanics

Oxygen breathers require 700 Oxygen every second, or they will start suffocating.

There are two sources of Oxygen: the Oxygen Generator (which can be used to fill up Oxygen Tanks, or rooms via Vents), and Oxygenite Shards.

Sources of Oxygen

Items

Some items can provide Oxygen when an Oxygen Tank or other oxygen source attached.

Item	Oxygen Supply Effect
Diving Mask	Supplemental Oxygen to the wearer
Diving Suit	Wearer exclusively breathes from Suit.
Combat Diving Suit	Wearer exclusively breathes from Suit.
Abyss Diving Suit	Wearer exclusively breathes from Suit.

Environmental

Hulls in submarines and other structures can contain Oxygen. They can hold as much Oxygen as they have volume.

Characters will breathe oxygen from the environment as long as they're not wearing a Diving Suit. Characters require the room to have at least 65% of its maximum Oxygen to breathe normally.

Oxygen in a room is replenished by Oxygen Generators via Vents. Oxygen Generators provide 100x their generated oxygen every second, split between all of their linked Vents.

Oxygenite Shards also generate Oxygen when exposed to the air. However, they also explode violently on impacts, and thus are not safe sources of long term Oxygen.

Sky Alien Artifact sucks Oxygen out of the room it's in at a rate of 50 000 per second.

CPR

Main article: CPR

In an emergency, CPR may be performed on a downed character to slow down or reduce their Oxygen Low affliction, if the subject has access to oxygen.
