Sleep Apnea

I am sure many have it but how many of you actually use the machine because of your pre surgery testing... I have had some surgeon say they want to sleep apnea test and others not even mention that I think its odd not like a standard protocol, 1 said it's because they want deep breaths in your lungs can't handle it so it is required.... and I think that a high risk then all surgeon should be doing it.... just a confusing process of the cash patients definitely not the same treatment or protocols
