The decompression time will rely upon how large the hole is. For a quick estimate, you may presume the air exiting throughout the gap will vacation within the pace of audio. Because the atmosphere drops in pressure as it moves with the gap, the efficient price at which the environment leaves is at about sixty% with the velocity of audio, or about two hundred meters/2nd for room-temperaure air (see derivation by Higgins): P = Po exp[-(A/V)t*(200m/s)]

The ideal info I've comes from the chapter on the effects of Barometric stress in Bioastronautics Details E book, Next edition, NASA SP-3006. This chapter discusses animal scientific studies of decompression to vacuum.

Heart rate may perhaps increase in the beginning, but will drop promptly thereafter. Arterial blood pressure level may also slide in excess of a duration of thirty to 60 seconds, when venous tension rises because of distention on the venous process by fuel and vapor.
