abstract：BACKGROUND:During most of the cruise, submarines are detached from their environment. Therefore, O(2) levels are relatively low (19 kPa, 144 mm Hg) and CO(2) levels are high (1 kPa, 7.6 mm Hg). There are, however, periods during ventilation of the submarine in which CO(2) levels drop and O(2) levels increase. The objec...
