What is brain perfusion pressure?
The brain is a complex organ that requires adequate blood supply to function normally. The blood flow to the brain is called perfusion. Cerebral perfusion pressure (CCP) is usually the strength of pressure in the arteries leading to the brain, blood pressure in jugular veins and intracranial pressure (ICP) inside the head. Medium arterial pressure can push blood into the head while ICP reduces CCP. The blood vessels in the brain called arteriols are usually able to spread to reduce pressure while they can limit them to increase them.
by self -regulation, the artery in the brain can spread and reduce so that the pressure in the brain is relatively constant. Therefore, changing blood pressure in the body does not usually have a great effect. If the brain perfusion pressure is not regulated in a normal way, this may result in pressure-in-exhaustive flow. There may be insufficient blood pressure in the brain, resulting in the cells starved with oxygen causes conditionalization called ischemia.
pThe romoic pressure in the brain can cause neurological damage and can cause parts of herniate organ to cause. Cerebral perfusion pressure usually must remain in a narrow range to be healthy and neurological activity healthy. It is often threatened after head injury and doctors can monitor CPP by monitoring jugular venous pressure and oxygen saturation. If the blood flow to the brain is too low, this saturation value will be reduced because more oxygen is available from what is available little blood supply.
cerebral perfusion pressure can also be monitored by assessing the metabolic activity of brain cells. Po positron emissions (PET) are often used to display these areas and compare this activity compared to CPP. The catheter is sometimes inserted into the brain to assess the metabolic state of the area. This method is usually invasive and the catheter presentation can change the physical condition of the measured areas.
Sometimes the patient's symptoms can be used to determine brain perfusion pressure. LeafFor example, catering can estimate the ICP based on whether someone is experiencing confusion or drowsiness. The average arterial pressure can be used with the resulting numerical estimate to determine CPP. The results of the victims of cranial injuries are often predicted by monitoring brain perfusion pressure, because blood flow and head pressure usually correlate with the function of the brain and its ability to heal.
