Choose the best description for this COPD patient's flow-volume loop(s) The COPD patient has low peak-flow generation but this is not a problem during typical exercise. Their spontaneous flow-volume loops are not constrained by their maximal expiratory flow-volume loop, so it will only be a problem with maximal exercise. The patient has obstruction that is primarily a problem during inspiration. They have a smaller RV compared to healthy, and they are flow-limited only during exercise. The COPD patient has expiratory but not inspiratory flow limitation The COPD patient has obstruction that is primarily a problem during inspiration. Their expiratory flow-volume loops during rest and exercise are flow-limited in this cartoon.
