Also know, what is the Monro Kellie doctrine?
The pressure–volume relationship between ICP, volume of CSF, blood, and brain tissue, and cerebral perfusion pressure (CPP) is known as the Monro–Kellie doctrine or hypothesis. The Monro–Kellie hypothesis states that the cranial compartment is inelastic and that the volume inside the cranium is fixed.
One may also ask, what is Cushing's triad? Cushing's triad is a clinical triad variably defined as having: Irregular, decreased respirations (caused by impaired brainstem function) Bradycardia. Systolic hypertension (widening pulse pressure)
Accordingly, which best describes the Monro Kellie principle?
The Monro-Kellie doctrine states that three things exist within the fixed dimensions of the skull: blood, cerebrospinal fluid, and brain. Brain tumors of any type effectively increase the amount of brain tissue. And last, but not least, the cerebrospinal fluid can back up in a condition known as "hydrocephalus".
What can decrease cerebral perfusion?
Blood flow to the brain is called cerebral perfusion pressure. Blood pressure and intracranial pressure affect the cerebral perfusion pressure. If the blood pressure is low and/or the intracranial pressure is high, the blood flow to the brain may be limited. This causes decreased cerebral perfusion pressure.
