IV Antibiotics

Si went into the hospital on Friday for a course of IV antibiotics. His pulmonary function test (FEV1) was 14%. He was 18% on discharge from a course of IV antibiotics 7 weeks ago. Si says he doesn't feel sick,  but he wants to push his FEV1 back up to baseline and  breathe better.  He is on Cipro and Merepenem, this is what pushed him back up  to 18% last hospitalization.
