Applicability of commonly used Caucasian prediction equations for spirometry interpretation in India

From: Indian Journal of Medical Research | Date: August 1, 2005| Author: | Copyright information

Background & objectives: The applicability of Caucasian prediction equations in interpreting spirometry data in Indian patients has not been studied. The present study was undertaken to see if Caucasian and north Indian prediction equations can be used interchangeably while interpreting routine spirometric data.

Methods: Forced vital capacity (FVC), forced expiratory volume in first second (FEV^sub 1^), and FEV^sub 1^/FVC ratio were recorded from 14733 consecutive spirometry procedures in adults. Predicted values and lower limits of normality were calculated using regression equations ...
