Mc. Noeljorand et H. Burnet, THE SENSATION OF RESPIRATION IN MEN EXPERIENCING HIGH-ALTITUDE CHRONIC HYPOXIA, Biological psychology, 43(1), 1996, pp. 1-12
Respiratory sensation was studied in seven European lowlanders during
a Himalayan expedition at over 6000 m. At rest, the ability to detect
added inspiratory resistive loads can be used to create a sensitivity
index P(A) taking response bias (B) into account based on Sensory Deci
sion Theory. The data indicate that respiratory sensitivity may be inv
olved in successful adaptation to hypoxia. Respiratory sensitivity imp
roved during the first stages of exposure to altitude and returned to
baseline after 17- and 27-day stays under chronic hypoxic conditions.
The improvement in respiratory sensation could be a primary signal in
the physiological and psychological adaptation to high altitude and ch
ange in sensation may reflect the degree of altitude adaptation.
