Zusammenfassung
The phase shift between oscillations of blood pressure (BP) and Doppler middle cerebral artery flow velocity (MCAFV) reflects continuous cerebral autoregulatory action. It is not known whether such a phase shift can also be observed for cortical hemodynamics ('microvascular level') assessed by near infrared spectroscopy (NIRS) and whether it is then also altered in pathophysiological conditions. This study investigates the phase relations between oscillations of BP, MCAFV and NIRS parameters in 38 healthy older adults and 28 patients with unilateral severe obstructive carotid disease. BP was recorded noninvasive…
