[The usefulness of the Chrispin-Norman score in the evaluation of pulmonary status in patients with cystic fibrosis]. / Die Wertigkeit des Chrispin-Norman-Score in der Beurteilung der pulmonalen Situation von Patienten mit Cystischer Fibrose.

Its objectivity and reproducibility having been checked by for independent researchers, the Chrispin-Norman score has proved to be a useful yardstick for evaluating pulmonary changes in cystic fibrosis. The correlation to arterial pO2 was r = 0.68, and to the Schwachman-Kulczycki score, r = 0.75. Scores still consistent with a good general clinical condition were 10.5 in patients under 8 years of age; 13.4 in patients aged between 8 and 13; and 15.5 in the 13-20 age group. An average increase of more than 2 points a year indicates a particularly high danger level.
