when I was recently in hospital, a machine was used on me to check my oxygen saturation level, it simply clamped on to a finger and gave a reading of 93%
I pointed to my CPAP and said this made it obvious that it was working for me
I hadnt heard of this machine before but I think that every sleep disorders dept should have one, also everyone complaining of cronic fatigue or exhaustion should be checked, its a very simple with an immediate result
