  • dural
  • The predictions not yet verified: (1) turning points B-low and B-high that represent physiological borders, (2) pathophysiological self-sustaining phases of low and high CSF pressure with corresponding minimal or maximal CSF volume (maximal dural sac collapse or distension) and no CSF transport, (3) compensated and de-compensated conditions. (scix.net)
  • drain
  • The EVD is set to drain into a closed, graduated burette at a height corresponding to a particular pressure level, as prescribed by a healthcare professional, usually a neurosurgeon or neurointensivist. (wikipedia.org)
  • jugular
  • This led to experiments with the Valsalva manoeuvre and jugular vein pressure from which his eponymous test was published. (wikipedia.org)
  • CPAP
  • The physiological impacts of continuous positive airway pressure (CPAP) are not yet fully understood. (asme.org)
  • pulse
  • The pulse rate tended to increase slightly, or remain the same, providing CSF pressure was not increased too greatly or too rapidly. (ahajournals.org)
  • hypertension
  • Discomfort sensation that occurred in rare cases was not a consequence of either hypo- or hypertension as such but of the absence of CNS ability to adapt rapidly to the changes of the pressure in the cranium. (semanticscholar.org)
  • presence
  • Sepsis-induced hypotension is defined as "the presence of a systolic blood pressure of less than 90 mm Hg or a reduction of more than 40 mm Hg from baseline in the absence of other causes of hypotension. (medscape.com)
  • After the cerebrospinal fluid is obtained, a variety of its parameters can be checked, including the presence of xanthochromia. (wikipedia.org)
  • Many laboratories rely on only the color of the cerebrospinal fluid to determine the presence or absence of xanthochromia. (wikipedia.org)
  • condition
  • Rhinorrhea or rhinorrhoea is a condition where the nasal cavity is filled with a significant amount of mucus fluid. (wikipedia.org)
  • demonstrated that 53 out of 58 patients with the condition had at least partially preserved BBBs, whilst having a high concentration of antibodies in the cerebrospinal fluid. (wikipedia.org)
  • suggests
  • Although the classic 'autoregulation curve' suggests that CBF is fully stable between these blood pressure values (known also as the limits of autoregulation), CBF may vary as much as 10% below and above its average within this range. (wikipedia.org)
  • hours
  • These adaptations to rapid changes in blood pressure (in contrast with changes that occur over periods of hours or days) are known as dynamic cerebral autoregulation. (wikipedia.org)
  • column
  • It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH2O (4°C) = 999.9720 kg/m3 × 9.80665 m/s2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m³ is used, giving 98.0665 Pa. (wikipedia.org)
  • usually
  • The buildup of fluid is usually resolved via mucus expulsion through the nostrils. (wikipedia.org)
  • Meningococcal rash can usually be confirmed by a glass test in which the rash does not fade away under pressure. (wikipedia.org)
  • solution
  • The bicarbonate buffer, consisting of a mixture of carbonic acid (H2CO3) and a bicarbonate (HCO− 3) salt in solution, is the most abundant buffer in the extracellular fluid, and it is also the buffer whose acid to base ratio can be changed very easily and rapidly. (wikipedia.org)
  • But buffers cannot correct abnormal pH levels in a solution, be that solution in a test tube or in the extracellular fluid. (wikipedia.org)
