Case Study: Reduce Costs, Expedite Outcomes with EnsoSleep PPG

In just 3 months, Chicago ENT/Chicago Sleep Center (CENT/CSC) transitioned more than 75% of their home sleep testing volume from flow-based devices to PPG-based devices, corresponding to a 92.5% reduction in cost per new HSAT device.

"We went from a $2,000 piece of hardware to a $150 piece of hardware, with no disposables. Those economics make EnsoSleep PPG very attractive." Scott Rice, Director of Ancillary Services

Celeste+ is a mobile app (Android and iOS) used to seamlessly collect and transfer data from pulse oximeters to EnsoSleep PPG.

EnsoSleep PPG Clinical Performance

These key metrics demonstrate the clinical impact of EnsoSleep PPG

Multi-Night Testing Addresses Inter-Night Variability

Relying on a single night of testing can lead to missed diagnoses in more than 1 in 10 patients.1 More than 1 in 4 patients1 may experience a jump in OSA severity by at least one category on subsequent nights. This can prevent patients from receiving the diagnosis and treatment they need to improve their overall health.

“The high rate of missed diagnosis due to single-night testing gives the sleep medicine community the opportunity to reexamine current testing methods and explore the benefits of multi-night testing. In terms of clinical effectiveness and the future of sleep medicine diagnostics, it may well be more productive to monitor one polysomnographic component for 20 nights rather than monitoring 20 components for one night.”

Remote Physiological Monitoring

Optimize patient outcomes with efficient, accurate RPM

Seamlessly monitor patient success on OSA therapies such as CPAP, implantable devices, oral appliances, and GLP-1s with long-term nightly measurement of AHI. 

EnsoData’s remote physiological monitoring (RPM) solution provides clinicians with valuable insights into a patient’s therapy success–gathered from the comfort and convenience of the patient’s home using affordable, easy-to-use PPG devices.

Simplify and accelerate the sleep testing, diagnosis and treatment workflow for sleep clinicians and sleep labs with one cloud-based solution for sleep study viewing, editing, and reporting.

EnsoSleep FDA-cleared AI-assisted sleep scoring and analysis solution  automates the scoring of studies, and reduces the time RPSGTs spend scoring PSGs and HSATs. Consistent, reliable results provide clinicians with more time to expand patient care, improve outcomes and treat more patients.

EnsoSleep produces an accurate Total Sleep Time (TST) for HSAT devices that do not calculate a measurement of sleep time. Including TST results in improved diagnostic accuracy for clinicians and patients and potential increased reimbursement.
