Background: Left ventricular ejection time (LVET) measured in central arteries is modified
during hypovolemia. We compared modifications of the pulse wave in a central artery …

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas
hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral …

Lower body positive pressure (LBPP) has been used in the treatment of haemorrhagic shock
and in offsetting g‐force induced fluid shifts. However, the middle cerebral artery blood flow …

The aim of the present study was to calculate critical closing pressure (CCP) of the cerebral
vasculature at rest and during exercise to estimate cerebral vascular tone. Five men and two …

We sought to quantify the contribution of cardiac output (Q) and total vascular conductance
(TVC) to carotid baroreflex‐mediated changes in mean arterial pressure (MAP) in the upright …

Rickards CA, Cohen KD, Bergeron LL, Burton BL, Khatri PJ, Lee CT, Ryan KL, Cooke WH,
Doerr DF, Convertino VA. Cerebral blood flow response and its association with symptoms …

The degree of stress has been compared between two protocols used for the measurement
of local cerebral blood flow (LCBF) in conscious rats. The first method involved acute …

Diminished constriction of arteries and veins following exposure to microgravity or bed rest
is associated with a reduced ability to augment peripheral vascular resistance (PVR) and …

We examined 1) whether global cerebral blood flow (CBF) would increase across a 6-h bout
of normobaric poikilocapnic hypoxia and be mediated by a larger increase in blood flow in …

Mild (0 to–20 mmHg) lower body negative pressure (LBNP) has traditionally been
considered to elicit reflex responses mediated by cardiopulmonary baroreceptors only …
