Hello everyone, I really want to buy something that will record/monitor my over night oxygen levels, but i don't know what i can buy apart from an Apple watch which i just cannot afford. There must be something under £100 that i can buy even if its second hand.
I use CPAP at night as i have severe sleep apnea, but i'm constantly waking up all night and when its time to get up in the morning i am feeing awful, really tired still, sluggish, almost like i'm drunk and i'm struggling to do anything. CPAP nurse says all looks fine from her end, G.P. doesn't seem at all interested so i need to monitor this myself. Please does anyone have any ideas what would record my oxygen levels overnight. Thanks x
