So current tidal volume is about 407 mL, and you calculated your ideal Vt should be about 469 mL at 6 mL/kg, and thought that would be low?   Interesting.  The rule of thumb is to subtract 1 mL/lb or 2 mL/kg IBW to bet alveolar minute vent.  Anyway, if we assume your IBW is 172 lbs (78 kg), we subtract 172 mL from 469 and get 298 mL which gives us a minute vent of 4.2 L/min. 

Run the learn function and see what you get, but be aware that your attempt to breathe normally during the Learn mode tends to result a significant over-calculation of the minute vent for sleep. Part of the titration process is gong to be adjusting the Va to get to your normal or ideal minute vent.

Yes that run of Learn would be with mask on and awake. And you have to breathe normal. Yippie. You get to simulate the frustration and oxymoronic state of a sleep study, but for free.

And yes as I understand it, it's inaccurate and will require some manual adjusting. It's a pick your poison situation. Do the Learn and let the machine get it wrong or do the math and see how close you get.

I thing you did very well!

(I bought mine used; forget how long ago. My friend failed out of cpap therapy and sold her gear to me. Recently I checked my hours for the first time. about 22,000 hours if I remember correctly.) I'm glad it's lasted.

I'm just a cpap user like you. I don't give medical advice. I hope to learn from you, and share my experiences with you. 
Seek the advice of a physician before seeking treatment for medical conditions including sleep apnea. Sleep-well
