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...
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...
The elimination of Xe133 from a deposit in the subcutaneous adipose tissue adjacent to the anterior tibial muscle was recorded by an external scintillation detector in 16 human subjects in sitting and...
The elimination of Xe133 from a deposit in the subcutaneous adipose tissue outside the anterior tibial muscle was recorded by an external scintillation detector in 16 human subjects during normal brea...
Direct measurement of helium elimination in mice.
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...
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...
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...
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) ...
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...
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...
INTRODUCTION: The rate of nitrogen elimination may be an important factor in evaluating the risk of DCS following dives. The present study determined the reproducibility of a method for evaluating nit...
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...
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...
