Another Paper from Sept, may have missed it being posted previously. Most of this is already known but good to have another publication behind it.

If anyone has access to the full article, would be great to get a read.

From the publication:
Significance: The smart phone based SRS alone, or in combination with routinely collected PSG signals can provide a non-invasive method to predict overnight ΔPes. The method has the potential to be automated and scaled to provide a low-cost alternative to EPM.

TLDR: Smart phone validation using gold standard validation of esophageal pressure works well as it help provide comparative measures at lower cost and easier access.
