Cerebral hemodynamics during graded Valsalva manoeuvres

Cerebral hemodynamics during graded Valsalva manoeuvres

The Valsalva maneuver (VM) produces large and abrupt changes in mean arterial pressure (MAP) that challenge cerebral blood flow and oxygenation. We examined the effect of VM intensity on middle cerebral artery blood velocity (MCAv) and cortical oxygenation responses during (phase I, II, III) and fol...
