(((..“significant changes compared with the rehabilitation group

despite oral steroids (resting energy expenditure −7.0% versus +4.1%,

and %VO2Resp −34.0% versus +0.7%, p = 0.001). Decrease of resting

energy expenditure and %VO2Resp correlated with reduction of residual

volume (p = 0.02 and p = 0.001) (((((

Principles of respiratory mechanics

Harvard school of public health, dep. of physiology

Note the chest is generally overinflated.

This is because the lungs are overinflated, and pushing the chest wall out.

Pink puffers learn to keep their lungs hyperinflated to keep the respiratory bronchioles

from collapsing, and this eventually changes the shape of the chest itself ("barrel chest",

"increased AP diameter", "increased total lung volume").
