12.4 Introduction to Adjustment of DLCO Measurements

Adjustments of DLCO measurements are described in detail in the 2005
ERS/ATS statement.

In the paper, however, the adjustment is described as a change of the DLCO
predicted values. After several discussions with opinion leaders, we have to
conclude that it is more common to compute a DL

adj

value that is computed

from the measured DLCO value. This DL

adj

value is then compared to the

(unchanged) predicted values. The following table describes this:

As can be seen from the table above, the %Predicted is the same if



= 1 /



.

This means that the equations of the ERS/ATS statement have to be inver-
ted (e.g. factor is multiplied instead of divided). If compared to the original
formulas in the ERS/ATS statement the following formulas are therefore
‘inverted’ (multiplication instead of division and vice versa).

Adjustment for hemoglobin

The following formula is applied to correct for hemoglobin:

Male adults (age > 15):

DL

adj

= DLCO / (1.7 × Hb / (10.22 + Hb))

Hb in g/dl

Female and children (age < 15):

DL

adj

= DLCO/ (1.7× Hb / (9.38 + Hb))

Hb in g/dl

Unit conversion:

Hb [g/dl] = Hb [mmol/l]/0.616

(according to other sources, the factor is 0.6206)

Allowed range for Hb:

0 to 100 g/dl

Default value male adults
(age > 15):

14.6 g/dl (9.00 mmol/l)

Default value female and children
(age < 15):

13.4 g/dl (8.26 mmol/l
