Hello. I got my sleep apnea study and diagnosis in 2007. Use my CPAP every night, have really bad apnea. At my first meeting at the weight loss clinic (11/22) the initial doctor I meet with told me I would need to get pulmonary clearance for my surgery. I've been so busy I haven't had a chance to setup that appt. I had my appt with the surgeon on 12/23 and when I told him I haven't made the appt yet for pulmonary clearance he said I don't need it, I just need to bring my machine along when I get the surgery. Anyway, they never stated I would need to do another sleep study so don't think that is needed. I go back on 1/9 so I hope to get clarification if the pulmonary clearance is needed.
