How does ICP affect BP?
When ICP becomes elevated, cerebral perfusion pressures decrease, and the net driving force of blood flow to the brain becomes decreased. The physiologic autoregulatory response to a decrease in cerebral perfusion pressure is to increase mean arterial pressures systemically and to vasodilate cerebral blood vessels.
Why does increased ICP cause Cushing's triad?
Increased ICP activates the Cushing reflex, a nervous system response resulting in Cushing's triad. As the ICP begins to increase, it eventually becomes greater than the mean arterial pressure, which typically must be greater than the ICP in order for the brain tissue to be adequately oxygenated.

What is intracranial hypertension?
Intracranial hypertension (IH) is a clinical condition that is associated with an elevation of the pressures within the cranium. The pressure in the cranial vault is measured in millimeters of mercury (mm Hg) and is normally less than 20 mm Hg.
What should be included in an ICP evaluation?
The evaluation of increased ICP should include detailed history taking, physical examination, and ancillary studies.
What is the pressure in the cranial vault?
The pressure in the cranial vault is measured in millimeters of mercury (mm Hg) and is normally less than 20 mm Hg. The cranium is a rigid structure that contains three main components: brain, cerebrospinal fluid, and blood. Any increase in the volume of its contents will increase the pressure within the cranial vault.
Where is CSF secreted?
It is secreted by the choroid plexus in the lateral ventricles, travels to the third ventricle via the foramen of Monroe. From the third ventricle, CSF reaches the fourth ventricle through the aqueduct of Sylvius. From here, it flows into the subarachnoid space via the foramina of Magendie and Luschka and is eventually reabsorbed into the dural venous sinuses by arachnoid granulation.
What is cerebral autoregulation?
Cerebral autoregulation is the process by which cerebral blood flow varies to maintain adequate cerebral perfusion. When the MAP is elevated, vasoconstriction occurs to limit blood flow and maintain cerebral perfusion. However, if a patient is hypotensive, cerebral vasculature can dilate to increase blood flow and maintain CPP.
Increased Intracranial Pressure (ICP)
Increased intracranial pressure, or ICP, is a serious medical condition that should be closely monitored by a team of healthcare professionals. Intracranial pressure is defined by a rise in pressure within a person's skull. This increase of fluid or blood in the skull can affect the individual's brain or spinal cord.
Causes of Increased Intracranial Pressure (ICP)
Several situations can give rise to ICP. Trauma to the head or brain can cause bleeding within the brain, which increases the amount of blood concentrated in that area. Swelling of the brain would cause a further increase in pressure.

Who studied intracranial pressure?
Several notable figures in the medical field, including Ernst von Bergmann, Henri Duret, Friedrich Jolly, and others experimented with intracranial pressure similarly to Cushing. Some of these researchers published similar findings concerning the relationship of intracranial pressure to arterial blood pressure before Cushing had begun experimenting. Cushing studied this relationship more carefully and offered an improved explanation of the relationship.
Which chemoreceptors are involved in the cushing reflex?
In the Cushing reflex, the central chemoreceptors are likely involved in the detection of ischemia, contributing to the sympathetic surge and hypertension in the first phase of the reflex, and work in opposition to the baroreceptors, contributing to the combined high sympathetic and parasympathetic activation.
Does Cushing reflex cause CPP to drop?
This effect is protective, especially during increased intracranial pressure, which creates a drop in CPP .
Does ischemia occur in the posterior cranial fossa?
It has also been reported that the presence of a Cushing reflex due to an ICP increase could allow one to conclude that ischemia has occurred in the posterior cranial fossa. Finally, the Cushing reflex may be one of many ways to identify if a patient has rejected a transplanted organ. Aside from the innate autoimmune response, ischemia in the cranial region has been detected with a transplanted organ that is being rejected. As such, the presence of a Cushing reflex due to ICP can indicate that ischemia may be occurring due to foreign organ rejection.
Is ICP measurement accurate?
Early recognition of this is crucial to the well being of the patient. Although direct measurement of ICP is possible, it is not always accurate. In the past, physicians and nurses have relied on hemodynamic changes or bradycardia, the late phase of the reflex, to identify the ICP increase.
Does Cushing's study show the cause and effect relationship between intracranial pressure and cerebral compression?
This research clearly displayed the cause and effect relationship between intracranial pressure and cerebral compression. Cushing noted this relationship in his subsequent publications. He also noted that there must exist a specific regulatory mechanism that increased blood pressure to a high enough point such that it did not create anemic conditions. Cushing's publications contain his observations and no statistical analysis. The sample size of the experiment is also not known.
