Can anyone mention 4 physiologic changes in lung parameters in someone who has COPD compared to someone who has a restrictive lung disease?


here's my way of not getting confused w/ Obstructive vs restrictive LD

For Restrictive lung diseases all are decreased except for a NORMAL FEV1

For Obstructive lung diseases all are increased except for a decreased FEV1 & VC.



1. Inc Compliance
2. Dec Elastic activity
3. Inc. TLC and RV
4. Dec FEV1/FVC ratio
