Calculator: Diffusing capacity for carbon monoxide (DLCO) correction of predicted value for anemia (conventional units)*


Calculator: Diffusing capacity for carbon monoxide (DLCO) correction of predicted value for anemia (conventional units)*

 
Input
 
Sex Male

Female
Age   Years old
Hgb  
DLCO predicted   mL CO (STPD)/min/mmHg

 
Results
 
Important: Inputs must be complete to perform calculation.

 
 
DLCO predicted corrected   mL CO (STPD)/min/mmHg
 
Decimal precision  

 
 

 
Notes
  • Predicted DLCO adjusted for hemoglobin is converted from mL CO/min/mmHg to mmol/min/kPa by multiplying by a factor of 0.3348.
  • 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-Factor is 10.22.
  • STPD: Standard Temperature and Pressure, Dry.
  • * This calculator uses conventional units (also known as US units and gravimetric units) as the default for inputs. Do not use this calculator if you are using SI units (Système international d'unités); please refer instead to the SI units version of this calculator.

 
Equations used
 
DLCO predicted corrected = DLCO predicted * (1.7 * Hgb /(Age-Sex-Factor + Hgb))

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
