Summary

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.

Detailed description

The data collected in the Patient Registry include: Parameters on general health, like previous illnesses, medications, height, weight, answers to symptoms queries and queries on quality of life (Asthma test, COPD test, Sinonasal Outcome Test 22) as well as results from the examined medical devices (body plethysmography, spirometry, sensors analyzing algorithm).

Conditions

• Nasal Polyps
• Asthma
• COPD
• Allergic Rhinitis

Interventions

Type	Name	Description
DEVICE	Sensor analyzing software (own development)	A software the research group developed. Analyzes acoustic and accelerator signals to measure airway obstruction.
DEVICE	Body plethysmograph	Body plethysmograph measures specific airway resistance
