to see if this response derives from hypoxia itself rather than from the change in breathing pattern that occurs during hypoxia , we measured lung vascular pressures , pleural pressure , cardiac output , and lung lymph flow in 12 anesthetized lambs that were ventilated at a fixed rate and tidal volume , first with air , then with 10-14 % o2 in nitrogen .
