NCT ID NCT07610122
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study checks if a Turkish version of a questionnaire called S3-NIV is reliable and accurate for people with chronic breathing failure who use a home breathing machine. Researchers will ask 120 stable patients to fill out the questionnaire to see how well it measures their difficulties and compliance. The goal is to provide a useful tool for doctors and patients in Turkey.
