 Washout Moment Analysis

The parameters Moment value (M0), Moment ratio 1 (MR1) and Moment 
ratio 2 (MR2) are calculated from measured values recorded during the 
multi-breath nitrogen washout test. Calculation of these parameters is 
defined in a paper published by Shao et al. [17].

Moment Analysis is performed using a standard mathematical technique. 
Once Functional residual capacity (FRC) is determined, a dilution number 
(

) is assigned to each breath: 

k

 is defined as the ratio of Cumulated 

Expired Volume (CEV) at the end of any breath k to FRC. End-tidal nitrogen 
concentrations are normalized and plotted versus dilution number for each 
breath, and this distribution is used for Moment Analysis. The normalized 
nitrogen concentration A

k

 is calculated as C

k

/C

0

, where C

k

 is end-tidal nitro-

gen concentration at the end of breath k, and C

0

 is the end-tidal nitrogen 

concentration at the last breath prior to washout.

The following picture shows a diagram of A

k

 versus dilution number (

) (see 

"Literature" 

on page 182 [17]).

In Moment Analysis the r
