Vent and Leak rates - update

Post by dataq1 » Fri May 13, 2022 8:57 pm

It's been a while since this was discussed, so I wanted to be sure that things have remained the same.

Respironics (and specifically Dreamstation 1) reports the total of Vent rate and Leak rate as Leaks.
Resmed (and specifically Airsense 11) reports the leak rate only (and ignores the vent rate)

If that is still accurate then it follows that a Resmed F30 mask at 10 cm with perfect seal would be reported as 37 L / min on the Dreamstation but 0 l/min on the Airsense 11.

Do I have that correct?

(technical specs for F30 found on page 6 of user guide shows vent flow rate at 37 l/min at 10 cm)
