Acoustic evaluation of the nitrogen washout time to study the process of intrapulmonary gas mixture
Abstract
A new method is proposed to study intrapulmonary gas mixture based on acoustic evaluation of nitrogen washout time while transferring the air breathing to breathing with the gas mixture of 21% O2 and 79% He. The study involving 12 healthy subjects and 14 chronic obstructive bronchitis patients made possible the quantitative assessment of the intrapulmonary gas distribution in an integral mode or separately for each the lung. The method is absolutely safe and may be used repeatedly to detect early disturbances of the intrapulmonary gas
mixture.
