About
Cadwell ApneaTrak provides physicians and sleep clinics with a comprehensive home sleep apnea testing (HSAT) solution using unattended Type 3 sleep studies. Patients wear the device at home while it records key physiological signals—thoracic and abdominal effort, airflow, oximetry, body position, snoring, nasal pressure, and thermistor readings—depending on the chosen device tier. Three ApneaTrak configurations are available: ApneaTrak Core captures essential channels and integrates with EnsoData AI for automated scoring and EnsoTST total sleep time estimation; ApneaTrak Legacy adds AASM best-practice channels including nasal pressure and thermistor; and ApneaTrak TST further extends this with ExG channels for EEG, EOG, EMG, and ECG derivations. The integration with EnsoData's AI engine (EnsoSleep) automates the labor-intensive manual scoring process, while EnsoTST uses AI to analyze cardiopulmonary signals to detect sleep vs. wake states—enabling clinicians to potentially bill under CPT 95800 instead of CPT 95806, improving reimbursement outcomes. All ApneaTrak devices pair with Cadwell's Easy III software platform for data management, review, and reporting. ApneaTrak is well-suited for sleep medicine specialists, pulmonologists, and ENT practices seeking to diagnose obstructive sleep apnea efficiently at scale, reduce patient burden, and improve diagnostic accuracy through AI-enhanced analysis.
Key Features
- Three HSAT Device Tiers: Choose from ApneaTrak Core, Legacy, or TST to match the level of data capture—from essential oximetry and airflow to full AASM best-practice channels with EEG, EOG, and EMG.
- AI-Powered Sleep Scoring (EnsoSleep): Integrates with EnsoData's AI engine to automatically score sleep studies, reducing manual review burden and improving scoring consistency.
- Total Sleep Time Estimation (EnsoTST): Uses AI to analyze cardiopulmonary data and detect sleep/wake states, enabling more accurate AHI calculations and potential access to higher-reimbursement CPT codes.
- Flow-Based HSAT Recording: Records full respiratory waveforms including nasal pressure, thermistor, and effort belts, providing visibility into the data underlying each diagnosis.
- Easy III Software Integration: Seamlessly connects with Cadwell's Easy III platform for data management, study review, reporting, and billing workflow support.
Use Cases
- Sleep medicine specialists offering home sleep apnea tests as a convenient alternative to in-lab studies for low-risk patients.
- Pulmonology and ENT practices expanding their diagnostic capabilities by adding HSAT without investing in a full sleep lab.
- Clinics seeking to improve AHI scoring accuracy and potentially qualify for higher CPT reimbursement codes through AI-based sleep time estimation.
- Healthcare systems managing high volumes of suspected sleep apnea patients who need scalable, cost-effective diagnostic screening.
- Researchers studying sleep-disordered breathing using multi-channel physiological data collected through portable home devices.
Pros
- Clinically Rich Data Capture: Flow-based recording with full waveform data gives physicians granular insight, beyond simple oximetry-only home tests.
- AI Automation Reduces Workload: Automated scoring and sleep time estimation through EnsoData significantly reduces the time clinicians spend on manual study review.
- Improved Reimbursement Potential: EnsoTST's sleep time analysis may allow use of CPT 95800 over CPT 95806, potentially increasing reimbursement per study.
- Scalable Device Options: Three device tiers let practices start with essential features and scale up to comprehensive polysomnography-adjacent studies as needed.
Cons
- Hardware Dependency: Requires purchase of proprietary Cadwell hardware devices, which may represent a significant upfront capital cost for smaller practices.
- Limited to Type 3 Studies: ApneaTrak is designed for unattended home testing and does not replace full in-lab Type 1 polysomnography for complex cases.
- Ecosystem Lock-In: Full functionality depends on Cadwell's Easy III software and EnsoData integration, limiting flexibility for practices using other clinical platforms.
Frequently Asked Questions
What type of sleep study does ApneaTrak perform?
ApneaTrak performs unattended Type 3 Home Sleep Apnea Tests (HSAT), which monitor breathing effort, airflow, oximetry, body position, and snoring without requiring the patient to visit a sleep lab.
How does AI improve the ApneaTrak workflow?
ApneaTrak integrates with EnsoData's EnsoSleep AI to automatically score sleep studies and with EnsoTST to estimate total sleep time by detecting sleep vs. wake states from cardiopulmonary signals—reducing manual review time and improving diagnostic accuracy.
What is the difference between ApneaTrak Core, Legacy, and TST?
Core captures essential channels (thoracic effort, airflow, snoring, oximetry, position) and supports AI sleep time estimation. Legacy adds AASM best-practice channels including nasal pressure and thermistor. TST adds three ExG channels for EEG, EOG, EMG, or ECG derivations.
Can ApneaTrak affect billing and reimbursement?
Yes. By including total sleep time measurement via EnsoTST, studies may qualify for CPT 95800 rather than CPT 95806, which can significantly increase reimbursement per study.
What software does ApneaTrak integrate with?
ApneaTrak devices integrate with Cadwell's Easy III software for data management, study review, and reporting, and with EnsoData's AI platform for automated scoring and sleep time analysis.
