ClinConnect Summary

This clinical trial is studying how well a new method of measuring breathing—using sensors and an algorithm—compares to a traditional technique called body plethysmography. The goal is to see if the new method is accurate enough to help identify breathing issues in both healthy adults and those with conditions like asthma, chronic obstructive pulmonary disease (COPD), and nasal polyps. Participants will perform a short breathing test while their breathing is monitored using both methods to gather data.

To be eligible for this study, participants should be between the ages of 65 and 74. The trial is looking for five healthy volunteers as well as five individuals each with allergic rhinitis, asthma, or COPD, all of whom must have a confirmed diagnosis. Participants can expect to wear different masks during the breathing tests, but there are some exclusions to keep in mind, such as recent surgeries or certain health conditions that could affect safety. Overall, this study aims to improve the accuracy of breathing assessments, which could lead to better care for those with respiratory issues.

Eligibility criteria

• Inclusion Criteria:
• • 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)
• Exclusion Criteria:
• • Pregnancy.
• • History of surgical procedures in the chest, larynx, throat (excluding tonsillectomy), or nasal area.
• * Recent illnesses or surgeries that pose a risk to the patient or prevent proper measurement (common contraindications for spirometry):
• • Recent (\<1 month) myocardial infarction.
• • Severe coronary artery disease with easily triggered symptoms.
• • Cerebral artery aneurysm.
• • Recent brain (\<4 weeks) or eye (\<1 week) surgery.
• • Severe cardiac arrhythmias.
• • Pulmonary tuberculosis.
• • Pneumothorax
• • Immediate postoperative period of lung surgery (\<1 day).
• • Dementia or confusion.
