연구 배경: 폐용적과 폐확산능의 정상예측식은 국가나 인종 등에 영향을 받는 것으로 알려져 있으나 우리나라 성인 대상으로 한 정상예측식이 폐용적은 없고, 폐확산능의 정상예측식은 있으나 많이 사용하지 않고 있다. 이에 기존에 사용하고 있는 여러 정상예측식 중 우리나라 성인에 가장 적합한 식을 선정하고자 본 연구를 수행하였다. 방 법: 비흡연, 건강한 성인을 대상으로 한양대학교 구리병원에서 모집한 남자 30명, 여자 33명 그리고 서울아산병원에서 모집한 남자 27명, 여자 34명을 대상으로 하였다. 이 대상자의 키와 몸무게를 측정하였고 전신체적용적기록(whole body plethysmography)로 폐용적을 측정하였으며 단회호흡법(single breath mothod)를 이용하여 폐확산능을 측정하였다. 가장 적합한 정상예측식은 실측치와 예측치의 차이인 잔차의 합이 최소가 되는 식으로 선정하였다. 결 과: 전폐용량의 잔차의 합이 최소가 되는 정상예측식은 한양대병원에서 모집한 대상자의 경우 남자는 ECSC 식 (잔차의 평균: 0.04 L), 여자는 Crapo/ Morris 식 (-1.04)이었고 서울아산병원에서 모집한 대상자의 경우 남자는 Goldman/Becklake식 (-2.35), 여자는 ECSC 식 (-4.49)이었다. 폐확산능은 잔차의 평균이 최소가 되는 식은 한양대병원 남자는 Roca 식 (잔차의 평균: -13.66 ml/min/ mmHg, 여자는 박 등의 식 (25.08)이었고 서울아산병원 남녀는 모두 박 등의 식(남자: -1.65 , 여자: -6.46)이었다.

Abstract
Background: The lung volume and diffusing capacity are influenced by ethnicity. However, there are no equations for predicting the normal lung volume in the adult Korean population, and there is only one equation for diffusing capacity. The aim of this study is to select the most suitable reference equation for the Korean population. Method: 30 men and 33 women at Hanyang University Guri Hospital, and 27 men and 34 women at Asan Medical Center in healthy nonsmoking adults were enrolled in this study. The subject’s age, gender, height, weight, lung volume by plethysmography, and diffusing capacity by a single breathing method were obtained. The most suitable equation with the lowest sum of residuals between the observed and predicted values for lung volume and diffusing capacity was selected. Result: At Hanyang University Guri Hospital, the equations with the lowest sum of residuals in the total lung capacity were ECSC’s equation in males (sum of residual: 0.04 L) and Crapo/Morris’s equation (-1.04) in women. At the Asan Medical Center, the equations with the lowest sum of residuals in the total lung capacity were Goldman/Becklake’s equation in males (sum of residual: -2.35) and the ECSC’s equation -4.49) in women. The equations with the lowest sum of residuals in the Diffusing capacity were Roca’s equation in males (sum of residual: -13.66 ml/min/mmHg) and Park’s in women (25.08) in Hanyang University Guri hospital and Park’s equation in all cases in the Asan Medical Center (male: -1.65 , female: -6.46). Conclusions: Until a reference equstion can be made for healthy Koreans by sampling, ECSC’s equation can be used for estimating the lung volume and Park’s can be used for estimating the diffusing capacity.
