Study Summary

Respiratory diseases are associated with high morbidity and mortality worldwide. Proper diagnosis and risk assessment of these conditions are essential for optimal management. Clinicians use three particularly useful tools to identify these conditions when assessing the patient's status: the stethoscope, the pulse oximeter, and the thermometer. The Pneumoscope is an all-in-one device including a digital stethoscope, a pulse oximeter, and a thermometer. This study aims to assess the performance and safety of the Pneumoscope in recording respiratory sounds, body temperature, non-invasive blood oxygen saturation levels and heart rate in children and adults.

Study Description

Respiratory diseases affect over 500 million people globally, ranking third in causes of death. Chronic obstructive pulmonary diseases impact 251 million individuals due to air pollution and tobacco smoke. Asthma is the most prevalent chronic disease in children, while pneumonia is the leading cause of death in children under 5. Respiratory infections are prominent in pediatric outpatient clinics, especially in low- and middle-income countries. Accurate diagnosis and risk assessment are crucial for effective management. Clinicians utilize three key tools: the stethoscope for auscultation, detecting abnormal breathing sounds; the pulse oximeter, indicating oxygen deficiency in inflamed lungs; and the thermometer, primarily for fever-related infections like pneumonia. Auscultation, while quick and non-invasive, suffers from user-dependent subjective interpretation, as highlighted by studies reporting low correct response rates, especially among non-pulmonologists. Pulmonary auscultation's sensitivity and specificity are notably low, particularly in unilateral or focal changes. Pulse oximetry, utilizing harmless light wavelengths, measures oxygenated hemoglobin concentration, with a saturation below 92% indicating hypoxia, albeit with reduced accuracy below 90%. Thermometers measure body temperature, with rectal measurement considered the gold standard in children, although non-contact methods remain contentious

The use of the Pneumoscope, a digital medical device, could address the above challenge. The Pneumoscope is designed to enhance respiratory disease diagnosis and provide heart rate, respiratory rate, pulse oximetry, and body temperature data. This project aims to evaluate its performance against gold standards in lung sound processing, pulse oximetry, and body temperature measurement. Furthermore, the Pneumoscope is envisioned to integrate artificial intelligence (AI) for future applications. Data on breath sounds, oximetry, heart rate, and temperature from patients with respiratory diseases will inform AI algorithms for disease recognition and risk assessment. Ultimately, this technology could enable remote diagnosis and follow-up, particularly beneficial for patients in low- and middle-income countries or with limited mobility. However, the current study focuses solely on assessing the Pneumoscope's performance as a standard digital stethoscope with integrated temperature and oximetry sensors, aiming to establish agreement with established clinical tools for digital lung auscultation, pulse oximetry, heart rate, and body temperature measurement.

This is a single center, open, non-controlled investigation that will be conducted at the University Hospitals of Geneva, Switzerland. This will be a non-inferiority study between Pneumoscope and CE marked comparable medical devices in children and adults.
