Spire Health

Spire Health developed continuous respiratory sensing technology to address a critical gap in chronic lung disease management. ​​‌‌‌‌‌‌‌​‌‌​​‌​​​​​​‌‌​‌‌‌​​​‌‌Pulmonologists struggled to monitor patients between clinic visits, relying on infrequent check-ins that often missed disease progression until patients experienced acute exacerbations requiring emergency care. Patients with COPD, asthma, and interstitial lung disease bore the burden most acutely—their respiratory status could deteriorate rapidly, yet they had no objective way to track breathing patterns at home. The problem was measurable: hospital readmission rates for pulmonary patients exceeded 20%, and many were preventable with earlier intervention. Existing alternatives were limited to patient symptom reporting and spirometry devices requiring active engagement, which patients often neglected. Early validation came when pulmonologists immediately recognized the clinical value of continuous breathing data, and the rapid adoption across U.S. practices—with over 150,000 patients wearing Spire sensors—demonstrated strong market demand. Patients' willingness to wear the unobtrusive device consistently signaled genuine need for passive, continuous monitoring that didn't require daily conscious effort.
