Listening to breath sounds with the stethoscope/auscultation is used by pulmonary physicians in conjunction with pulmonary function, signs and symptoms, oxygen saturation and diagnostic testing to admit, follow and discharge patients from hospital. Of these, only auscultation routinely ceases upon discharge from Hospital. Healthcare utilization statistics have shown that for more than a decade, readmission after discharge for an exacerbation of COPD or severe asthma (or chronic heart failure) remains a major problem. The Strados RESP Biosensor has been designed to extend the range of lung sound recording both geographically and temporally to improve the standard of care when access to continuous monitoring has been replaced by periodic or no monitoring. The primary purpose of this study is to assess the associations between RESP Biosensor-acquired lung findings and subjective measures of respiratory symptoms as measured by validated measurement tools, and objective measure of respiratory physiology as determined by home spirometry
