PULMONARY EFFECTS OF COLD ACCLIMATIZATION AND NOREPINEPHRINE CALORIGENESIS,
Abstract
The effects of cold acclimatization on pulmonary function during norepinephrine calorigensis were studied. Norepinephrine resulted in amarked increase (85%) in the pulmonary minute volume in both warm- and cold-acclimatized rats. This increase in the warm-acclimatized rats was accomplished entirely by increasing the respiratory rate, whereas in the cold-acclimatized rats the increase in pulmonary minute volume was achieved for the most part by increasing the tidal volume with a slight increeas in respiratory rate. Cold acclimatization was associated with a greater efficiency of oxygen extraction before, during and after the infusion of norepinephrine. (Author)
