Preliminary findings of the studies described are as follows: 



Airway Resistance 



While airway resistance and work of breathing were in fact elevated as pre- 

 dicted during residence in nitrogen-oxygen at 4 atmospheres, the degree of this 

 respiratory stress was easily managed by all subjects, no gross change in pul- 

 monary-blood gas exchange occurred in rest or in exercise, and the subjects 

 were able to perform physical, psychomotor, and intellectual tasks well through- 

 out the entire exposure period. Furthermore, no gross indication of progressive 

 deterioration of physiological or psychomotor performance occurred during the 

 exposure.
