The effect of ambient pressure on inert gas elimination during decompression was investigated using human subjects breathing air in a dry hyperbaric chamber. This was done by measuring nitrogen recove...
Measurement of helium elimination from man during decompression breathing air or oxygen
human helium elimination decompression
2009/7/20
Air breathing was compared with oxygen breathing during decompression from an 80-20 percent helium-oxygen dive to a depth equivalent to 120 fsw (4.6 ATA) in a dry chamber to see which was the most eff...

Nitrogen elimination during steady-state hyperbaric exposures
Nitrogen elimination human decompression
2009/7/17
Nitrogen elimination was measured in six divers during steady-state exposures in an oxygen-nitrogen atmosphere at 1, 2, and 3 ATA using both oxy-helium and pure O2 as washout gases. This was accomplis...
Effects of hyperbaric treatment on carbon monoxide elimination in humans

2009/7/15
A theoretical model of carbon monoxide elimination from the acutely poisoned individual is presented. The model is derived from a one-compartment system with the rate-limiting step that of alveolar ve...
A method for measuring nitrogen elimination after air diving has been developed in which a subject breathes air instead of oxygen or helium-oxygen. Accuracy is improved with this method because only n...
Effect of intravascular bubbles on perfusate flow and gas elimination rates following simulated decompression of a model tissue
human Health diving decompression
2009/7/14
This study deals with the monitoring of the elimination rates of gases from a porous cylindrical model of the human tissue during simulated single-stop decompression schedules. The data suggest the pr...
Hypothermia impairs but hyperthermia does not promote inert gas elimination in the rat
hypothermia hyperthermia inert gas elimination animal rat
2009/7/14
The volume of nitrogen eliminated (VN2) and washout rate constant (k) during a 2-h period of O2 breathing in the rat was altered in response to changes in body temperature. VN2 and cardiac output (Q) ...
Moderate hypercapnia:cardiovascular function and nitrogen elimination
CO2 carbon dioxide nitrogen elimination hypercapnia nitrogen cardiovascular
2009/6/12
Elevated carbon dioxide concentrations frequently encountered in diving operations may have cardiovascular effects. If so, changes in nitrogen loading and elimination may be induced. To study this pos...
Tissue nitrogen elimination in oxygen-breathing pigs is enhanced by fluorocarbon-derived intravascular micro-bubbles
Algorithms Analysis of Variance Fluorocarbons administration dosage animal Microbubbles
2009/6/3
The present study tested the hypothesis that intravascular micro bubbles generated by i.v. infusion of a 2 % dodecafluoropentane (DDFP) emulsion will enhance tissue denitrogenation during oxygen breat...

2009/6/2
Negative pressure breathing (NPB) increases the rate of nitrogen elimination, which is thought to be due to an increase in cardiac output due to augmented venous return to the heart. Hyperoxia, howeve...
Oxygen-Enhanced Breath-hold Diving, Phase I: Hyperventilation and Carbon Dioxide Elimination
breath-hold Hyperventilation carbon dioxide loss of consciousness
2009/5/6
Hyperventilation (HV) is commonly used to extend breath-hold time by eliminating carbon dioxide to delay the hypercapnic stimulus to end breath-hold. The chief hazard is that loss of consciousness ma...
