Abstract
Presented are concepts for monitoring cardio-respiratory function of a patient. One such concept employs an optical sensor unit () for sensing light from tissue of the patient in response to temporary airway pressure changes provided via a respiratory support unit (). By sensing variations in blood volume in the central site vein in response to temporary airway pressure changes, venous information of the person may be obtained.
