ResMed Vs Philips - This Is Disturbing! 🤯

In this https://sleephq.com case study, I compare the Philips Respironics & ResMed auto algorithms.

For the first time in history, we now have a powerful analytics platform that can be used to compare cpap performance & treatment efficacy.

Here are two studies that I highly recommend reading. They do validate my findings.

Here's what Philips has to say about their algorithm.
Sleep Review: In a couple of brief paragraphs, please generally summarize the approach used in your auto-adjust CPAP machine’s algorithm to detect sleep-disordered breathing events?

Philips Respironics: The main goal of the REMstar Auto algorithm is to normalize sleep by delivering the lowest CPAP pressure. What makes the REMstar Auto algorithm unique is its sophisticated three-layered algorithm. Unlike other auto-titrating devices in the market, the REMstar Auto can manage a respiratory event in the early stages rather than waiting for it to occur.

The primary function of the algorithm is to conduct proactive analysis of the patient’s upper airway and its potential to collapse. It makes subtle, programmed CPAP pressure adjustments in response to detected changes in flow.

The second layer consists of programmed responses to apneas, hypopneas, flow limitations, and vibratory snores.

In the third layer, the algorithm operates in a variety of exception conditions. For example, the algorithm ceases to increase pressure for patients who may experience sleep-disordered breathing events that are not responsive to pressure increases (such as central apneas). The algorithm decreases CPAP pressure when the patient is experiencing a large mask leak. The result is clinically proven, effective therapy at minimal CPAP pressure.

Sleep Review: How does your product respond once a sleep-disordered breathing event is detected?

Philips Respironics: With its proactive and continuous analysis throughout the therapy session, the REMstar Auto algorithm has the unique ability to deliver just enough CPAP pressure necessary to ward off a potential event. Since the pressure delivered at any given time is slightly higher than the pressure level necessary to open the airway, if an event does occur, the device does not need to rapidly respond by increasing pressure quickly. When the REMstar Auto detects a clustering of events, it determines the patient’s airway to be unstable and slowly increases pressure to achieve a higher level of CPAP for a new 5-minute period.

The REMstar Auto detects and responds to apneas, hypopneas, flow limitations, and vibratory snores. To detect apnea or hypopnea, the algorithm calculates a baseline patient flow based on a moving average of patient flow. The baseline flow and any changes in flow are based on the algorithm’s analysis of four parameters of the flow signal: flatness, roundness, peak, and shape. This precise recognition of unique patient flow patterns is the reason why the REMstar Auto reacts better than other devices.

Sleep Review: Finally, what was the basis or reference for incorporating the above-described approach to detecting and responding to sleep-disordered breathing events?

Philips Respironics: The theory of the algorithm was developed based on clinical understanding and practices used in titrating CPAP pressures during a PSG titration process. Additionally, there has been extensive clinical and bench test validation of the algorithm’s effectiveness. These studies have been conducted by Philips Respironics and independent medical professionals. Several studies have been published in medical and other trade journals.
