FDA-Cleared Home Sleep Apnea Test
Wesper Lab: Airflow data. No cannula. No compromise.
Two wearable biosensor patches measure thoracic and abdominal effort and an FDA-cleared airflow signal, so you get direct respiratory data from a home study.
- FDA-Cleared Airflow
- No Nasal Cannula
- Multi-Night as Standard
AHI correlation to in-lab PSG
Direct Measurement
Two effort channels, measured directly.
Two independent effort channels, thoracic and abdominal, produce RIP-equivalent signals. That makes central apnea detection and positional analysis possible at home, over multiple nights.
- Complex cases and comorbidities, such as AFib, heart failure and complex insomnia
- Confirmatory studies, or whenever direct respiratory data is required
- Central apnea detection and positional analysis at home
- Multi-night and longitudinal follow-up on the same patient record
Signals
Nine FDA-cleared signals, over one night or many.
Every channel is recorded and preserved in the provider portal, so reviewers see the raw trace behind each scored event.
Wesper Lab also records respiratory rate, skin temperature, snoring and movement as investigational signals, outside the FDA clearance.
- Airflow, without a nasal cannula
- Thoracic effort and abdominal effort
- Pressure and body position
- SpO2, PPG and heart rate
- Sleep staging

With over 13 years of experience in full-time sleep medicine, one persistent challenge has been finding a reliable home sleep test capable of accurately scoring respiratory events. Wesper addresses this with impressive precision, particularly in detecting central apneas. What's even more impactful is the ability to remotely monitor objective treatment response, especially for advanced neuromodulation therapies. Wesper empowers us to make truly informed clinical decisions, all from the comfort of the patient's home. An exceptional innovation.
Does Wesper Lab need a nasal cannula?
No. Wesper Lab measures an FDA-cleared airflow signal from its two wearable patches, so patients sleep without a nasal cannula.
Where are the patches worn?
One patch sits on the chest and one on the abdomen. Together they capture thoracic and abdominal effort, body position and airflow.
Can Wesper Lab detect central sleep apnea?
Wesper Lab's two independent effort channels support central apnea detection at home.
Can patients test over more than one night?
Yes. Multi-night testing is standard with Wesper, and repeat studies stay on the same patient record for longitudinal follow-up.
Who is Wesper Lab for?
Wesper Lab suits complex cases, patients with comorbidities such as AFib, heart failure or complex insomnia, confirmatory studies, and any case where direct respiratory data is required. It is indicated for adult use only.
