Hose volume - Willw - 02-26-2024

I recently received a smaller diameter heated cpap hose.  If the machine determines the air pressure would a smaller diameter hose produce proper pressure but less volume of air?

If you received a Philips branded heated tube, the Dreamstation 2 will automatically detect it and provide settings to adjust heat.

If tubing is made smaller, does that affect the VOLUME of the AIR ENTERING MASK?

No, it affects velocity in the tube. A narrower tube or pipe can deliver the same air volume or pressure, but any given volume (cfs, mL/sec) will flow faster in a smaller tube.

Thank you for your help.
