Your own data
This machine writes detailed therapy data to its SD card, which means you can look at your own results rather than relying on a summary screen. Worth knowing what the numbers mean before you do.
Specifications are taken from manufacturer documentation. Pressure settings are prescribed by the clinician managing your therapy and are not something to change based on a specification page.
