Effect of prolonged exposure to elevated carbon monoxide and carbon dioxide levels on red blood cell parameters during submarine patrols.
Calcium, magnesium, and phosphorus metabolism, and parathyroid-calcitonin function during prolonged exposure to elevated CO2 concentrations on submarines
submarine CO2 carbon dioxide
2009/7/17
Studies of calcium and phosphorus metabolism and acid-base balance were carried out on three Fleet Ballistic Missile (FBM) submarines during prolonged exposure to elevated concentrations of CO2. The a...
Effect of prolonged exposure to 0.5% CO2 on kidney calcification and ultrastructure of lungs
air animal guinea pig
2009/7/17
Guinea pigs were exposed for up to 8 weeks to 0.5% CO2, 21% O2, and balance N2. Control groups of the same age were kept simultaneously in environmental chambers on air. A slight increase in PaCO2 and...
