Associated with Pressure and Hyperbaric Oxygenation

Limitations Associated with Pressure and Hyperbaric Oxygenation 

Science is built up with facts, as a house is with stone. But a collection of facts is no more science than a heap of stones a house. 

Interruption of oxygen administration decreases the toxic effects on the pulmonary and cerebral nervous system, especially if the periods of exposure to oxygen are of short duration (K5, P9). However, there is evidence that even routine oxygen therapy may give rise to pulmonary alterations (P18). 

The predominant involvement of the respiratory tract in oxygen toxicity is probably due to the fact that the lungs are the first and only organ to come in contact with the full Pio,. Dyspnea, capillary congestion, alveolar exudation, hemorrhage, atelectasis, swelling of alveolar walls with encroachment on alveolar spaces, fragmentation of basement membranes between alveolar and endothelial cell layers, accumulation of exudate between the basement 

In Donald s experiments (D16, D17), those not reaching a convulsive end point showed a tendency toward a slight increase in beta activity and increased synchronization of delta activity in the EEG. Coupled with this was a decrease in the amount and voltage of the dominant alpha frequency (6-12 cps). Single high-voltage spikes appeared infrequently these were symmetrical and bilateral.
