EFFECT OF DECOMPRESSION AND RECOMPRESSION ON BLOOD PRESSURE. 

 RESPIRATORY RATE. AND PULSE RATE: DOG 



Alterations in blood pressure, respiratory rate and pulse rate of dog decompressed in ten seconds from a gauge 

 pressure of 65 lb after 1^ hours' exposure, followed by recompression (interval of ten minutes) to a pressure of 30 

 lb (oxygen) for twenty-five minutes. Pressure was then lowered to atmospheric in twelve minutes, and oxygen 

 inhalation continued for seventeen minutes. Preceded by period of oxygen breathing (thirty minutes), compression 

 of dog was again repeated at a pressure of 65 lb for period of forty-five minutes, followed by ten seconds' decom- 

 pression. After interval of twelve minutes, dog was recompressed to a pressure of 30 lb for twenty minutes 

 (oxygen inhalation).
