RESEARCH ON THE DYNAMICS OF PULSATILE BLOODFLOW IN THE HUMAN PULMONARY ARTERIAL SYSTEM.

Abstract

Development of an apparatus to enable continuous measurement to be made in man of pulmonary capillary blood flow with simultaneous intravascular pressure measurement was continued. A pneumatic flowmeter was built which is capable of continuously recording gas flow from a 1500 litre whole body perspex plethysmograph when a human subject within it inhales nitrous oxide gas. The gas uptake by the subject's lungs is proportional to the pulmonary capillary blood flow. The flowmeter has a linear response from 0 - 200 mls/second and a frequency response which is uniform to 5 cycles/second. (Author)
