Abstract

|
|
A measurement of compliances of respiratory apparatus was carried out to establish normal values of Koreans. Forty-six healthy men, average age of 22, and average predicted vital capacity of 94.3%, were selected for the study.
Passive pressures and various presuure-volume curves of the respiratory apparatus, such as total respiratory system, the lung and the thoracic cage were determined under the various lung volume and then, corresponding compliance values, at the lung volume from the level of ERV to 750 ~1250cc, were computed. The measurement of the lung pressure was made by means of intra-esophageal balloon mothad and thoracic cage pressure was calculated by substracting the lung pressure from the total respiratory pressure.
The ralues of compliance of total respiratory system, the lung and the thoracic cage were 0.1050.050, 0.2060.048 and 0.1610.043. L/cm. H~0 respectively.
