Abstract
Clinical and radiological findings, quantified by special scores, in 36 patients with cystic fibrosis are compared with lung function measurements, including the ratio of RV[residual volume]/TLC [total lung capacity] and FEV[forced expiratory volume]/VC [vital capacity] and the arterial blood gases [PaO2, PaCO2] at rest and during exercise. Although respiratory function tests correlated well with the pulmonary finding score and the chest radiographic score, distinction of 3 severity groups was possible only by a vector calculation of the blood gases in PaO2-PaCO2 diagram, at rest and during exercise. Measurements of PO2 [partial pressure] and PCO2 at rest and on exercise appear to be a helpful adjuvant to routine spirometry for the individual appraisal of the degree of lung involvement, performance and care level.
