Arterial oxygen saturation (SaO2) patterns during sleep in obstructive sleep apnoea (OSA) alone and the overlap syndrome. SaO2 patterns in a patient with a) OSA alone and b) overlap syndrome demonstrating the persisting pattern of desaturation in the overlap patient whereas the OSA patient returns to normal SaO2 between apnoea events.
