Help with research on etCO2 monitoring in oxygen and CPAP masks

Hi,
I am conducting a survey on general practices regarding oxygen and CPAP masks and how etCO2 monitoring might fit in.

As my thanks for participating, you will be entered into a sweepstakes with the opportunity to receive either $100 or $200.

The survey is posted at: https://www.surveymonkey.com/s/CO2withMasks

I appreciate you help!
