Again based on my experience in medicine over 40 years, pressure measurements with water or mercury rising in calibrated tubes is the most reliable method of accessing a baseline level. If a water manometer tells you that your device is producing 13 cm/H2O pressure and it's digital readout says 10 ...

Do any of you CPAP users own a manometer? I spoke to CPAP.com yesterday about one and they recommended this one which sells for $78.00: I'm newcomer to the world of personal CPAP and picked up an F&P HD-200 water manometer that cpap.com offered for $49.00 – https://www.cpap.com/productpage/fisher-p...

Perhaps that is there to simulate the effect of the "normal" mask leak rate. It shouldn't make a difference on the pressure inside the F&P humidifier chamber being used as part of this device. Without the device in hand to test what happens if that 'vent' is temporarily closed its just a mystery. T...

That will do it, I have made several but currently use a F&P manometer. Being new to CPAP use, and assuming that a water manometer is still the affordable gold standard for measuring pressure, I recently took delivery of an F&P HD-200 water manometer. http://www.pbase.com/critterdoc/image/155167190...
