Intracranial pressure (ICP) is the pressure exerted by fluids such as cerebrospinal fluid (CSF) inside the skull and on the brain tissue. ICP is measured in millimeters of mercury and at rest, is normally 7–15 mmHg for a supine adult. This equals to 9–20 cmH 2 O, which is a common scale used in lumbar punctures. [1]
Under normal conditions, regular movements such as leaning forward, normal heartbeat and breathing can cause changes to the ICP. Intracranial monitoring accounts for this by averaging measurements over 30 minutes in non-comatose patients. Readings between 7-15mmHg are considered normal in an adult, 3-7mmHg in children, and 1.4-6mmHg in infants. [4]
Cerebral perfusion pressure, or CPP, is the net pressure gradient causing cerebral blood flow to the brain (brain perfusion).It must be maintained within narrow limits because too little pressure could cause brain tissue to become ischemic (having inadequate blood flow), and too much could raise intracranial pressure (ICP).
Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.

The DASH diet includes heart-healthy foods that lower blood pressure. ... Normal blood pressure fluctuates throughout the day, but healthy blood pressure is considered to be lower than 120/80 mm ...
It can cause complications such as vision impairment due to intracranial pressure , permanent neurological problems, reversible neurological problems, seizures, stroke, and death. [1] However, aside from a few Level I trauma centers, ICP monitoring is rarely a part of the clinical management of patients with these conditions.
Presence of midline shift is an indication for neurosurgeons to take measures to monitor and control ICP. [1] Immediate surgery may be indicated when there is a midline shift of over 5 mm. [3] [4] The sign can be caused by conditions including traumatic brain injury, [1] stroke, hematoma, or birth deformity that leads to a raised intracranial ...
A 2021 study linking strawberries to heart health found eating 2.5 servings of strawberries per day for four weeks improved LDL cholesterol levels in adults with obesity and high cholesterol.
