Comparing two methods of cheek support during lung function testing

Comparative Evaluation of the Use of a Mouthpiece With Integrated Cheek Support vs. Manual Cheek Support During Respiratory Oscillometry Measurements

NA · Politecnico di Milano · NCT06537362

This study tests which cheek support method during lung function tests—manual support by an expert or a built-in mouthpiece—helps people feel more comfortable and gives more accurate results.

What this trial studies

This study evaluates the accuracy of respiratory impedance measurements during oscillometry using two different cheek support methods: manual support by an expert and an integrated cheek support in a mouthpiece. It is a prospective, randomized, cross-over study involving participants aged 5 to 75 years who will undergo measurements of facial morphology and respiratory impedance. The study aims to assess not only the measurement accuracy but also the comfort level of patients during the procedure. Participants will complete a questionnaire regarding their comfort after the measurements.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged between 5 and 75 years who can follow study procedures.

Not a fit: Patients with physical or mental conditions that prevent them from participating in the study may not benefit.

Why it matters

Potential benefit: If successful, this study could improve the accuracy and comfort of lung function testing for patients.

How similar studies have performed: While similar approaches have been explored, this specific comparison of cheek support methods in respiratory oscillometry is relatively novel.
