Tissue oxygen saturation during hyperthermic progressive central hypovolemia.
During normothermia, a reduction in near-infrared spectroscopy (NIRS)-derived tissue oxygen saturation (So2) is an indicator of central hypovolemia. Hyperthermia increases skin blood flow and reduces tolerance to central hypovolemia, both of which may alter the interpretation of tissue So2 during central hypovolemia. This study tested the hypothesis that maximal reductions in tissue So2 would b...

متن کاملOxygen saturation determined from deep muscle, not thenar tissue, is an early indicator of central hypovolemia in humans.
OBJECTIVE To compare the responses of noninvasively measured tissue oxygen saturation (StO2) and calculated muscle oxygen tension (PmO2) to standard hemodynamic variables for early detection of imminent hemodynamic instability during progressive central hypovolemia in humans. DESIGN Prospective study. SETTING Research laboratory. SUBJECTS Sixteen healthy human volunteers. INTERVENTIONS ...
متن کاملNoninvasively determined muscle oxygen saturation is an early indicator of central hypovolemia in humans.
Ten healthy human volunteers were subjected to progressive lower body negative pressure (LBNP) to the onset of cardiovascular collapse to compare the response of noninvasively determined skin and fat corrected deep muscle oxygen saturation (SmO2) and pH to standard hemodynamic parameters for early detection of imminent hemodynamic instability. Muscle SmO2 and pH were determined with a novel nea...
متن کاملAngiotensin II during Experimentally Simulated Central Hypovolemia
Central hypovolemia, defined as diminished blood volume in the heart and pulmonary vascular bed, is still an unresolved problem from a therapeutic point of view. The development of pharmaceutical agents targeted at specific angiotensin II receptors, such as the non-peptidergic AT2-receptor agonist compound 21, is yielding many opportunities to uncover more knowledge about angiotensin II recepto...
