A Comparative Study of Ultrasonic and Conventional Spirometers in Patients With Chronic Respiratory Diseases
Status: Recruiting
Location: See location...
Intervention Type: Diagnostic test
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This study compares a handheld ultrasonic spirometer with a standard hospital spirometer in adults with chronic respiratory diseases. Each participant will complete lung function tests using both devices. The study aims to determine whether the ultrasonic device provides accurate and reliable measurements for use in clinical or home settings.
