Extension of Central Nervous and Visual System Oxygen Tolerance in Physical Work.
Abstract
This report documents effects of two different patterns of exercise (I-Intermittent and II-Incremental) on two critical aspects of oxygen poisoning (i.e. Central Nervous System and Visual System). It is conceivable that oxygen- exercise interactions are associated with measureable changes that may provide some clue regarding possible causes of accelerated convulsions, or some means to identify unusually susceptible individuals in advance. There are indications that hyperoxic impairment of peripheral vision may also be accelerated by concurrent exercise. Two related Projects were designed to investigate such possibilities in parallel, by making objective measurements of central nervous system and visual responses to oxygen-exercise exposure at 2.0 ATA, along with concurrent measurements of ventilatory, temperature, pulmonary, and cardiac responses. Emphasis was placed upon the measurement of indices that were found to be altered during the earlier, continuous hyperoxic exposures of men at rest (Predictive Studies V) (6-9), carried out in this laboratory with Naval support. Results of the two Projects (Central Nervous System and Visual System Oxygen Tolerance), which were closely integrated in both design and performance, have been combined in a single report to facilitate interpretation and application of this information.
