EFFECTS OF OXYGEN AND DEXTRO-AMPHETAMINE UPON WORK DECREMENT

摘要

Following medical examination and familiarization with mask breathing and leak-check procedures, 72 young, male, basic airmen volunteers were given 50 minutes of practice at a compensatory pursuit task involving simulated aircraft indicators and controls. Upon completion of practice, subjects were randomly assigned to the 6 combinations provided by 3 mixtures of air (60, 21, or 12 per¬cent oxygen) and 2 drug conditions (placebo and 5 mg. d-amphetainine) and then required to perform the work task for 4 consecutive hours. The single and joint effects of oxygen and d-amphetamine upon proficiency throughout the period of work were appraised
