...M. PALEOLOGOS; E. STONE; S. BRAUDE Hyperventilation (HV) and respiratory alkalosis are associated with hypophosphataemia, although the extent and duration of HV required to produce changes in serum phosphate levels are not known. We sought to characterize the effects of HV, with or without dextrose...

... oxygenation in response to inhaled carbon dioxide, hyperventilation and supplementary oxygen on ascent to 4680 m over 3 days. At sea level, inhaled CO 2 resulted in a significant rise in cerebral regional oxygenation [from mean 69.6% (S.D. 2.4% to 71.1±2.3%; means±S.D.; P < 0.001). At 4680 m, CO 2...

....) and heart rate by 27 ± 2 beats/min. 3. Nineteen of the subjects respired eucapnically during exercise, increasing ventilation by 4.1 ± 0.5 litres/min. Eight subjects hyperventilated (7.1–19.6 litres/min) and decreased end-tidal P co 2 by 8.2 to 15.1 mmHg during the last minute of exercise. 4...

... in the form of new magnesium-selective electrodes, the effect of respiratory alkalosis induced by voluntary overbreathing for 30 min on circulating ionized magnesium was studied in eight healthy subjects. 3. The total plasma magnesium concentration was not modified by hyperventilation. On the contrary...

..., voluntary isocapnic hyperventilation during exercise did not increase breathlessness above that normally associated with that level of exercise. 3. These results suggest that it is reflexly driven ventilation, and not simply the level of ventilation itself, which relates to the level of breathlessness...

... hyperventilation. 2. Total respiratory resistance ( R os) was measured by the forced oscillation technique before and after 90s voluntary hyperventilation. End-tidal P co 2 during hyperventilation was varied by altering inspired CO 2 concentration. When end-tidal Pco 2 fell during hyperventilation...

Phasic inspiratory activity in normal subjects was present only during periods of voluntary hyperventilation, increasing with tidal volume, whereas in patients with airflow obstruction inspiratory activity was present even during resting breathing...
