Abstract

Pulmonary function test (PFT) is a test method to determine respiratory disease. In order to obtain accurate PFT results, it is absolutely necessary to induce the inspector and cooperate with the patient. This study was to observe the importance of understanding and posture of the patient in spirometry. In 2016, 110 healthy experimenter performed spirometry; 1) only heard the explanation, 2) watching video and inspector,s demonstration, 3) twisting legs and bending shoulder. FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF were measured by spirometry. FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF were significantly increased before and after the understanding the test method. There was a significant difference in FVC, $FEV_1$, and PEF in the false posture. Reproducibility was significantly different in the experimenter' comprehension and false posture. This study provides accurate understanding of the patient and correct posture should be maintained during the examination to obtain correct and reproducible results of PFT.

폐기능검사는 호흡기 질환을 진단하는 검사방법으로 정확한 검사 결과를 얻기 위해서는 환자의 이해와 협조가 절대적으로 필요하다. 본 연구는 폐활량검사에서 환자의 이해도와 자세의 중요성에 대하여 실험하였다. 2016년 110명의 건강한 사람을 대상으로 1) 검사자의 설명만으로, 2) 동영상 상영과 검사자의 시연 후, 3) 자세에 제한을 주기 위하여 다리를 꼰 후 어깨를 구부린 상태로 측정하였다. 폐활량 검사기기를 이용하여 FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF를 측정하였다. 대상자가 검사방법을 이해하기 전과 후의 FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF가 유의적으로 증가하였다. 잘못된 자세에서 검사 시 FVC, $FEV_1$, PEF의 유의적으로 차이가 있었다. 재현성은 대상자의 이해도와 자세이상에서, 적합성은 자세이상에서 유의적인 차이를 보였다. 폐기능 검사의 정확한 결과를 도출해 내기 위해서는 검사 시 환자의 정확한 이해와 올바른 자세를 유지하여야 신뢰할 수 있는 결과를 얻을 수 있을 것이다.
