Compliance is the ease with which a change occurs. For pulmonary compliance that means the relative amount of pressure needed to make a change in volume. As such emphysema may have a normal or increased compliance because the decrease in elastic tissue and alveolar tissue reduces resistance to inflation.. It would be easy to confuse the normal to increased compliance of COPD with the increased lung volume that often accompanies those conditions. High lung compliance (low effort for the amount of volume change) is generally associated with healthy lungs but as stated earlier in some conditions it can be higher than normal. -- Dbrouse ( talk) 21:55, 18 August 2008 (UTC)
The change in volume is calculated by subtracting the initial volume from the final volume, but the author uses the opposite method for calculating change in pressure. If the initial intra-pleural pressure is -5mmH2O and the final intra-pleural pressure is -10mmH2O, then the change in pressure would be "-10mmH2O-(-5mmH2O)=-5mmH2O" not "-5mmH2O-(-10mmH2O)=5mmH2O". This would mean that Compliance=0.5L/-5mmH2O=-0.1mmH2O^-1 — Preceding unsigned comment added by Confusedaboutcompliance ( talk • contribs) 21:55, 12 September 2015 (UTC)

This article seems to be a mixture of lung compliance and total chest (lung and chest wall) compliance, and the two are not made clear. eg at one point it is stated that lung compliance is an important measurement in respiratory physiology. I'm sure it is important , but I suspect that it is rarely if ever measured as it needs an oesophageal balloon! Pysifr ( talk) 03:41, 16 September 2017 (UTC)
In addition, patients often have difficulties inhaling air as well. This is due to the fact that a highly compliant lung results in many Atelectasis which makes inflation difficult.
I don't follow. How does increased compliance result in atelectasis? Is there any merit to this statement? Datapass talk | contribs 16:09, 18 June 2021 (UTC)
