Input
 

Sex	Female
	Male
Age		Years old
Hgb		g/dL gm/L gm/dL mcg/dL mg% mg/dL mg/mL ng/mL
DLCO Predicted		mL CO (STPD)

 

Results
 

DLCO Predicted Corrected		mL CO (STPD)
Decimal Precision   0 1 2 3

 

 

Notes

• In this calculator, mcg is the abbreviation for micrograms.
• Predicted DLCO adjusted for hemoglobin is converted from mL CO per min per mmHg to mmol per min per kPa by multiplying by a factor of 0.3348.
• STPD: Standard Temperature and Pressure, Dry.
• For females of any age, and children less than 15 years old the Age-Sex-Factor is 9.38
• For males 15 years old or older, the Age-Sex-Facor is 10.22

 
Equations used
 

DLCOPredictedCorrected = DLCOPredictedCorrected

DLCO Predicted Corrected = DLCO Predicted * (1.7 * Hgb /(Age-Sex-Factor + Hgb))
