The Medical Mask is one of the two items used with the Oxygen Tank to protect against Airless Environments. the other is the Gas Mask.

NOTE: this will not protect you very well in Depressurised Environments. use a Space Suit and Jetpack with this to protect in these circumstances.

See Howto:Survive an airless environment for more information.
