Agreement Between Accelerometric and Acoustic Signals Utilizing Algorithm and Body Plethysmograph in Detecting Nasal and Oral Specific Airway Resistance
The goal of this observational study is to learn about the agreement between sensors analyzing algorithm and body plethysmography in measuring oral and nasal breathing in healthy adults, and in patients with chronic rhinosinusitis, asthma and chronic obstructive pulmonary disease. The main question it aims to answer is: • Is the algorithm-based method accurate enough in analyzing respiratory obstruction as compared to body plethysmography (reference method)? Participants will perform a short breathing protocol (oral and nasal breathing with different masks) during which time their breathing is monitored with both methods.
• 5 healthy and asymptomatic volunteers with regard to lungs and nose
• 5 patients with allergic rhinitis or nasal polyps (diagnosis of allergic rhinitis confirmed by a PRICK test or specific Ig E antibody tests and Nasal polyposis diagnosed by an ENT specialist, with endoscopy)
• 5 patients with asthma (diagnosis of asthma based on peak expiratory flow (PEF) monitoring, spirometry, or other appropriate objective measurement methods performed by a pulmonologist
• 5 patients with Chronic Obstructive Pumonary Disease (diagnosis of COPD based on spirometry (post-bronchodilator Forced Expiratory Volume/ Forced Vital Capacity (FEV1/FVC) ratio below 0.70)
