Testing how well people with lung fibrosis can breathe through inhalers

This is an observational study designed to understand how well patients with pulmonary fibrosis can inhale through different types of inhaler devices. Researchers want to measure your peak inspiratory flow rate—how fast you can breathe in—and how long each breath takes when using inhalers with medium and high resistance. This information will help doctors choose the most effective inhaler devices for patients like you.

People with pulmonary fibrosis often have difficulty breathing, and the type of inhaler device prescribed can make a big difference in how well medication reaches the lungs. By measuring how well patients with this condition can inhale through different devices, researchers hope to provide guidance on which inhalers work best for these patients.
