Other potential causes of decreased lung compliance are pneumonia (doesn't make sense here for reasons given by usmile1 in subcomments), NRDS, and pulmonary edema. FA2019 p. 651.
Recall : Formula for compliance Change in volume / Change in pressure
From the patients graph - a large change in pressure is required to bring about a change in volume , signalling decreased compliance * Restrictive lung disease ( intrinsic)
