For me, it delayed it about a month and half for the insurance to be submitted. Of the many medical clearences for surgery that was requested, one was from the Pulmonary Specialist.
At that visit, they did a chest X-Ray and a series of breathing test performed in something about the size of a phone booth. Those results were fine. However, since snoring was listed on my questionairre, he ordered a take home sleep test which I wore for 2 nights. This indicated severe sleep apnea, with an AHI of 29, and very loud snoring. Next was an overnight hospital CPAP titration test to determine the pressure levels for a CPAP machine. The scheduling of this took a few days, and another few days for the results to come back. Another visit to the Pulmonary Specialist, and I was fitted with a CPAP machine. I was required to be on the CPAP machine and show compliance for 3 weeks before he would sign my medical clearence.
I was told that each individual is different in how long it takes them to adjust to sleeping with the machine. Some patients take off the mask in the middle of the night. This adjustment period can be anywhere from a few days to several weeks. I accepted that I have severe sleep apnea, and that the machine was needed, and adjusted right away. My new AHI is 0.9 now. However, the Pulmonary Specialist and Bariatric Surgeon where at the same facility and had a set agreement of 3 weeks on the machine period.
That is how it delayed me. Someone already discussed the need for treating CPAP and how important it is.
