Had my sleep study on Friday night. Apparently I have pretty bad sleep apnea. I was having a lot of occurences so they put a mask on me. The nurse started me on low pressure but had to increase it fairly high for me. I was started on a CPAP but was switched to a BiPAP machine. So i guess I just wait to get my official diagnosis. I was thinking I have OSA but I might have CSA as well.
