All severe PEx episodes treated with intravenous (IV) antibiotics (ATB) between 1 January 2017 and 31 December 2021 in CwCF using home telemonitoring were analyzed. Symptoms and home spirometry data were collected 45 days before and up to 60 days after each IV ATB course. We defined three response profiles based on terciles of baseline forced expiratory volume in 1\u2009s (FEV<jats:sub>1<\/jats:sub>) recovery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 346 IV ATB courses for PEx were administered to 65 CwCF during the study period.

The magnitude of FEV<jats:sub>1<\/jats:sub> drop and a greater delay in the initiation of treatment correlated with a low response level. On the 14th day of the IV treatment, a FEV<jats:sub>1<\/jats:sub> recovery less than 94% of baseline was associated with a nonresponder profile.<\/jats:p><\/jats:sec><jats:sec><jats:title>Interpretation<\/jats:title><jats:p>Home spirometry may facilitate the early recognition of PEx to implement earlier interventions.
