Sentence examples for lost autoregulation from inspiring English sources
The remaining hypoperfused tissue – with lost autoregulation – is pathophysiologically divided relative to a well-defined perfusion threshold into two compartments; namely, the 'penumbra' and the 'oligaemia'oligaemia
It is also important to note that different vascular beds will lose autoregulation at different blood pressure values.
An interesting parallel may be drawn with another study by Wilson et al. (2005), who found that glabrous skin with sympathetic blockade was still able to autoregulate flow during blood pressure variations, whereas non-glabrous skin lost its capability of autoregulation.
When blood pressure falls below a given value (autoregulatory threshold), however, such autoregulation is lost.
When autoregulation is lost due to AKI, each new hypotensive episode decreases glomerular perfusion [ 21], causing recurrent focal ischemic injury and postponing recovery of kidney function according to some studies [ 22].
It is true that we may need to implement a different strategy so that we do not lose RIs of autoregulation.
When arterial pressures are low, renal autoregulation adaptation is lost and renal vascular resistances are increased, with subsequent renal hypoperfusion and ischemia.
In the setting of acute kidney injury (AKI), however, as demonstrated in several animal models [ 6- 9] this autoregulation may be lost and further episodes of hypotension may be associated with marked decreases in renal blood flow (RBF) and glomerular filtration rate (GFR).
Autoregulation of cerebral blood flow was lost within 4 minutes of occlusion, probably as a result of hypoxia, combined with hypotension.
