Pulmonary hemodynamics, minute ventilation (VE) and oxygen uptake (VO2) were serially measured during inhalation of 13 %O2 for 15 min. There was a wide variablility in the pulmonary, vascular response to acute hypoxia. ,The initial increase in VE and the magnitude of change in VO2 were significantly lower in subjects developing a 25 % or great increase in mean pulmonary arterial pressure during hypoxic breathing. These results suggest that the ventilatory response to acute hypoxia plays a significant role in the pulmonary vascular response to acute hypoxia, and blunted initial ventilatory response to acute hypoxia may be a physiological adaptation to enhanced responses of pulmonary vessels., Acta medica Nagasakiensia. 1994, 39(4), p.82-86}, pages = {82--86}, title = {Ventilatory and Pulmonary Vascular Responses to Acute Hypoxia in Patients with Chronic Obstructive Lung Disease}, volume = {39}, year = {1994} }
