About
Wesper is a clinically validated, FDA-cleared home sleep apnea testing (HSAT) platform designed to bridge the gap between convenient at-home testing and rigorous in-lab diagnostics. Using a flexible silicone patch with gentle adhesives, patients can undergo comprehensive sleep studies in the comfort of their own home—without the discomfort of traditional cannulas, belts, or wiring. The device captures a full suite of Level 3 HSAT signals including thoracic and abdominal respiratory effort, airflow, body position, SpO2, heart rate, and sleep staging, along with advanced metrics like hypoxic burden, leg movement, snoring, skin temperature, and respiratory rate. Wesper's autoscored reports include AHI 3%/4%, ODI, RDI, central apnea index, T90, and longitudinal trends across up to 45 data points, giving clinicians a richer picture of patient sleep health. Providers access all patient data through a cloud-based portal, with overscoring capabilities for clinical review. With a 99% patient success rate and 95% correlation to in-lab polysomnography studies, Wesper is built for precision sleep medicine—trusted by sleep specialists, primary care physicians, and health systems seeking a scalable, patient-friendly alternative to traditional sleep labs. It is particularly well-suited for multi-night, longitudinal sleep monitoring across diverse patient populations.
Key Features
- FDA-Cleared Level 3 HSAT: Captures thoracic effort, abdominal effort, airflow, SpO2, heart rate, body position, and sleep staging—meeting clinical-grade diagnostic standards.
- Advanced Sleep Metrics: Goes beyond basic AHI to deliver hypoxic burden, ODI, RDI, central apnea index, leg movement, snoring, and skin temperature for a comprehensive clinical picture.
- Comfortable Wearable Patch: Flexible silicone patch with gentle adhesives ensures all-night wear without skin irritation, dramatically improving patient compliance compared to traditional HSAT devices.
- Cloud-Based Provider Portal: Providers access autoscored reports and patient sleep data quickly through a secure, cloud-based portal with overscoring capabilities for clinical review.
- Multi-Night Longitudinal Tracking: Supports up to 45 longitudinal trend data points across multiple nights, enabling richer sleep health monitoring and more informed clinical decisions.
Use Cases
- Sleep specialists ordering at-home diagnostic studies for patients suspected of having obstructive or central sleep apnea
- Primary care physicians screening patients for sleep-disordered breathing without referring them to an in-lab sleep center
- Health systems scaling sleep medicine programs by deploying a remote, reusable diagnostic device with a cloud-based review portal
- Clinical researchers conducting multi-night, longitudinal sleep studies across diverse patient populations including varying ages, BMIs, and comorbidities
- Telehealth providers integrating remote sleep diagnostics into virtual care workflows for patients who cannot easily access traditional sleep labs
Pros
- Clinical-Grade Accuracy: 95% correlation to in-lab polysomnography and FDA clearance give providers confidence in diagnostic results without requiring a sleep lab setting.
- High Patient Success Rate: 99% patient success rate and a wire-free, comfortable patch design significantly reduce setup errors and test failures common with traditional home sleep tests.
- Rich, Actionable Data: Reports go well beyond a basic AHI score, including hypoxic burden, sleep staging, and leg movement—enabling more nuanced clinical decision-making.
Cons
- Provider-Focused Pricing: Wesper is primarily sold through healthcare providers rather than directly to consumers, making individual access limited without a clinical referral.
- Requires Mobile App Pairing: Patients must pair the device via a mobile app, which may present a barrier for less tech-savvy users or those without compatible smartphones.
- Not a Full PSG Replacement: While highly correlated with in-lab studies, it is a Level 3 HSAT and may not replace full polysomnography for all complex sleep disorder cases.
Frequently Asked Questions
Is Wesper FDA-cleared?
