NIVI Mask, good morning everyone since August lasts year I have worn overnight a NIVI Mask to combat my C02 build up and help reduce it. I generally put my mask on around 9pm and I can tolerate it till around 3.30am within that time period my Oxygen is reduced from 4 Ltrs to 1 Ltr. Can I ask does anyone wear their mask throughout the day instead of overnight? Or do the majority of us wear them just at bedtime?
All your comments will be gratefully welcomed.
Thanks
