Skin blood flow changes and tissue deformations produced by cylindrical indentors.
Since skin blood flow as a function of applied pressure depends on many factors, one may find different curves within each group of subjects, making separation of groups difficult. A dimensional analysis has been out which indicates that the percent decrease in skin blood flow associated with external loading is primarily a function of only three variables: the ratios of bone depth and bone dia...
متن کاملCarbomer 940 Hydrogel Enhances Capillary Blood Flow and Tissue Viability in a Skin Burn Wound
Objective- To evaluate the application of Carbomer 940 hydrogel on saving zone of stasis in skin burn wound. Design- Experimental study Animals- Twenty rats. Procedures- After shaving the backs, a ‘comb burn’ was contacted bilaterally on the dorsum of the rats 0.5 cm lateral and parallel to the midline by usin...
متن کاملSweating and Skin Blood Flow Changes during Progressive Dehydration
Unfortunately, in situations of protracted and high sweat secretion, the body water content will become progressively reduced, and the blood volume slowly declines. This is well tolerated within healthy individuals. However, the regulation of blood pressure has a higher homeostatic priority than does temperature regulation, since low pressures cannot support adequate tissue perfusion, and will ...
متن کاملForearm skin tissue dielectric constant measured at 300 MHz: effect of changes in skin vascular volume and blood flow.
Skin tissue dielectric constant (TDC) values measured via the open-ended coaxial probe method are useful non-invasive indices of local skin tissue water. However, the effect of skin blood flow (SBF) or skin blood volume (SBV) on TDC values is unknown. To determine the magnitude of such effects, we decreased forearm SBV via vertical arm raising for 5 min (test 1) and increased SBV by bicep cuff ...
متن کاملSkin blood flow changes during apneic spells in preterm infants.
Changes in skin blood flow during apneic spells were determined in 18 preterm infants using a diode laser Doppler flow meter without light conducting fibres. Heart rate, nasal air flow, impedance pneumography, skin and incubator temperature and laser Doppler skin blood flow were recorded simultaneously in each infant. During 212 apneic spells with a duration of 11.6 +/- 7.5 s (mean +/- S.D.) (r...
