Step by Step calculation
Formula To Calculate Lung Age:
Lung Age for Female = ((0.0342 x h) - 1.578 - m) / 0.0255
Lung Age for Male = (0.0414 x h - 2.19 - m) / 0.0244
where,
h is height
m is Measured FEV1
Enter patients gender, height, and measured FEV1.0, then derive the age for which that FEV1.0 value is 100% predicted.
