Ventilatory response to arousal in patients with OSA and healthy subjects
Inspired minute ventilation (VI) expressed as a percentage of the pre-arousal sleeping level for 60 s following spontaneous arousal in 22 OSA patients (supine) on optimal CPAP and 25 healthy young subjects (left lateral position) with no CPAP from a previous study (Jordan et al. 2003). Mean ±s.e.m. presented. *P < 0.05 difference between groups at the indicated time points.
