BACKGROUND: In healthy volunteers, we investigated the ability of the pulse oximeter–
derived peripheral perfusion index (PPI) to detect progressive reductions in central blood …

The effects of sodium thiopental on postganglionic muscle sympathetic nerve activity
(MSNA) and the reflex augmentation in MSNA produced by hypotension Were examined in …

Exposure to lower body negative pressure (LBNP) leads to an increased activation of the
sympathetic nervous system (SNS) and an increase in muscle sympathetic nerve activity …

The experimental objective was to determine whether moderate to severe hypoxemia
increases skeletal muscle sympathetic nervous activity (MSNA) in resting humans without …

A comment on this article appears in" Cerebrovascular autoregulation may be the probable
mechanism responsible for fentanyl-and sufentanil-induced increases in intracranial …

The reproducibility of heart rate variability (HRV) measures during graded lower body
negative pressure (LBNP) have not been studied in sufficient detail. Active college age men …

We measured the effects of inhaled isoflurane on hypoxemia-induced changes in the
diameter of small mesenteric (capacitance-regulating) veins, sympathetic efferent neural …

Hemodynamics, muscle sympathetic nerve activity (MSNA), and forearm blood flow were
evaluated in 12 normal subjects before, during (1 and 7 h), and after ventilatory …

The aim of this study was to examine the contribution of arterial shear to changes in flow-
mediated dilation (FMD) during sympathetic nervous system (SNS) activation in healthy …

HEMORRHAGE AND HEART FAILURE are conditions characterized by reduced cardiac
output and arterial pressure. In both conditions, neurohormonal mechanisms are evoked in …
