The article discusses increasing orthostatic tolerance through physical countermeasures.
Topics include cardiovascular system, neurodegenerative diseases and symptomatic …

Haemodynamic oscillations occurring at frequencies below the rate of respiration have been
observed experimentally for more than a century. Much of the research regarding these …

Objectives Autonomic nervous system dysfunction has been implicated in visceral
hypersensitivity. However, the specific contribution of the parasympathetic nervous system …

Variability in arterial pressure and cerebral blood flow has traditionally been interpreted as a
marker of cardiovascular decompensation, and has been associated with negative clinical …

Numerous driven techniques have been utilized to assess dynamic cerebral autoregulation
(dCA) in healthy and clinical populations. The current review aimed to amalgamate this …

This review summarizes evidence in humans for an association between hyperventilation
(HV)-induced hypocapnia and a reduction in cerebral perfusion leading to syncope defined …

Introduction: Like heart rate, blood pressure (BP) is not steady but varies over intervals as
long as months to as short as consecutive cardiac cycles. This blood pressure variability …

Tolerance to central hypovolemia is highly variable, and accumulating evidence suggests
that protection of anterior cerebral blood flow (CBF) is not an underlying mechanism. We …

Ischemic stroke produces the highest adult disability. Despite successful recanalization, no-
reflow, or the futile restoration of the cerebral perfusion after ischemia, is a major cause of …

Introduction. Oscillatory patterns in arterial pressure and blood flow (at∼ 0.1 Hz) may protect
tissue oxygenation during conditions of reduced cerebral perfusion and/or hypoxia. We …
