Fast and slow components of cerebral blood flow response to step decreases in end-tidal PCO2 in humans.

Fast and slow components of cerebral blood flow response to step decreases in end-tidal PCO2 in humans.

This study examined the dynamics of the middle cerebral artery (MCA) blood flow response to hypocapnia in humans (n = 6) by using transcranial Doppler ultrasound. In a control protocol, end-tidal PCO2 (PETCO2) was held near eucapnia (1.5 Torr above resting) for 40 min. In a hypocapnic protocol, PETC...
