Comment: Obstructive Sleep Apnea (OSA) vs. Central Sleep Apnea (CSA) The point is, that in OSA during apnoic pause (no air flow from and out of the nose), you should see chest movement (there is obstruction in retroglossal space). In case of CSA, the problem is with the CNS respiratory centers and there is no obstruction, thus in case of apnoic pause (again no air flow), you will not see chest movement.
