Wesper has redefined home sleep apnea testing by launching the first and only FDA-cleared, cannula-free airflow monitoring system. This wearable solution uses two biosensor patches placed on the chest and abdomen to directly capture thoracoabdominal movement, thereby computing airflow without requiring a nasal cannula. Unlike traditional tests that rely on indirect signals such as oxygen desaturation or arterial tone, Wesper delivers real-time respiratory analysis, including airflow tracking, body position, and central apnea detection. This system allows patients to conduct multi-night testing from home with clinical-grade accuracy and greater comfort.

Accurate airflow measurement is essential for diagnosing sleep apnea, particularly for identifying hypopneas and differentiating between obstructive and central sleep events. Traditional home sleep tests that omit airflow data often miss or misclassify these events, leading to underdiagnosis and improper treatment. By directly measuring airflow and respiratory effort, Wesper meets American Academy of Sleep Medicine (AASM) recommendations and aligns with gold-standard PSG testing. It also avoids issues tied to signal loss or user discomfort common with nasal cannulas, thereby improving data quality and patient compliance.

Wesper’s innovation marks a significant advancement in sleep diagnostics, blending high clinical precision with a user-friendly design that improves patient comfort and adherence. As awareness grows about the connection between sleep apnea and chronic disease, the need for accurate and scalable diagnostic tools becomes increasingly urgent. Wesper’s wearable, reusable, and validated system meets this need, setting a new standard for home sleep testing and enabling earlier and more reliable diagnoses that can transform long-term patient outcomes.
