If compliances of lung (CL), chest wall (CCW) and respiratory system (CRS) of this patient were measured and compared to corresponding compliances of a healthy person at the same lung volumes, which of the following combinations of changes in these parameters will most likely reflect this patient's condition?

without having to stop and get his breath back. He has a 30-year history of smoking two packs of cigarettes per
day He is noted to be using accessory muscles for respiration. Wheezing on expiration is noted upon
auscultation.
If compliances of lung (CL), chest wall (CCW) and respiratory system (CRS) of this patient were measured and
compared to corresponding compliances of a healthy person at the same lung volumes, which of the following
