Nebulizer treatments and chest physiotherapy (PT) will be administered four times a day. If you are sleeping, you will be woken up. You must be an active participant in your therapy whether at home or in the hospital. We do try to schedule treatments during waking hours so most treatments will be completed between 8 a.m. and 10 p.m. unless otherwise arranged. Pulmonary function tests (PFTs) may be done before you are given antibiotics and then up to twice more before you leave. Spirometry will be done once a week. This should be done with your morning treatment and can be done in the lab or your room. Your care team will advise you when PFTs will be scheduled.
