Changes of cerebral blood flow velocity during cognitive activity.

Cerebral blood flow velocity during neonatal seizures.

AIM To determine if cerebral blood flow velocity increases during all types of neonatal seizure, and whether the effect is due solely to an increase in blood pressure, transmitted to the cerebral circulation when autoregulation is impaired. METHODS Seizures were diagnosed in 11 high risk neonates using cotside 16 channel video-EEG polygraphy. EEG, cerebral blood flow velocity (CBFV) using tra...

Regional cerebral blood flow velocity changes after indomethacin infusion in preterm infants.

Cerebral blood flow velocity was assessed during infusion of indomethacin over 30 minutes. Eleven preterm infants with symptomatic patent ductus arteriosus were studied on 12 occasions. Indomethacin infusion was associated with a significant reduction in time averaged mean velocity (TAMV), peak systolic velocity (PSV), and end diastolic velocity in both the anterior cerebral artery and middle c...

Cerebral blood flow velocity underestimates cerebral blood flow during modest hypercapnia and hypocapnia.

To establish the accuracy of transcranial Doppler ultrasound (TCD) measures of middle cerebral artery (MCA) cerebral blood flow velocity (CBFV) as a surrogate of cerebral blood flow (CBF) during hypercapnia (HC) and hypocapnia (HO), we examined whether the cross-sectional area (CSA) of the MCA changed during HC or HO and whether TCD-based estimates of CBFV were equivalent to estimates from phas...
