(Equations and Sources for Predicted PFT Values)
JHH - Johns Hopkins Hospital
The Johns Hopkins Hospital predicted equations are derived from a combination
of several sources of data in the literature. 남은공기량 (VC, SVC, 및 FVC) are computed from the equations of Goldman and Becklake:
VC = 0.1626*키(inches) - 0.031*연령(년) - 5.335 [남성]
VC = 0.1321*키(inches) - 0.018*연령(년) - 4.360 [여성]
참고: 1 inch= 2.54 cm
Equations for 남은공기량 (또는 잔기량) are also taken from Goldman and Becklake:
RV = 0.0687*키(inches) + 0.017*연령(년) - 3.447 [남성]
RV = 0.0813*키(inches) + 0.009*연령(년) - 3.900 [여성]
온허파용량 (TLC, 또는 전폐용량) is found by adding predicted values for RV
and VC.
Equations for 기능잔기용량 (FRC) are derived from data
reported by Bates, which were in turn derived from the data of Goldman:
FRC = 0.1295*키(inches) - 5.19 [남성]
FRC = 0.1220*키(inches) - 5.01 [여성]
Equations for FEV1/FVC are derived from the data of Miller, Kory, Gaensler,
Tiffeneau, and Pemberton & Flanagan:
FEV1%= 91.4 - 0.2*연령(년) [All]
Predicted values for FEV1 are computed by multiplying the predicted
FEV1% by the predicted FVC.
폐포용적에 대한 단숨 확산능력의 비율 (DL/VA)은 Burrows의 데이터에서 유도되었다:
DL/VA= 5.36 - 0.0246*연령(년) [All]
Predicted DLCO is computed by multiplying the predicted DL/VA by the
predicted TLC.
