Prevalence

Won - Figure 34

FIG. 34: In a few small, mostly retrospective, studies TE-CSA appears to occur with a prevalence of approximately 5–15% in OSA patients who undergo initial titration.^[23,27,28] This is in contrast to primary CSA, which is very rare and has a reported prevalence of about 0.4%. There is currently no way to predict which patients are going to develop TE-CSA, and there is no way to predict in which patients TE-CSA will persist and become a chronic problem.^[29]
