What does the medical abbreviation CPP mean?
Cerebral Perfusion PressureCerebral Perfusion Pressure
What is normal perfusion?
Well pulse pressure is systolic (top) minus diastolic (bottom). So the value you get should be between 30-49 to be normal.
What is the normal value of coronary perfusion pressure?
15-70
How is coronary perfusion rate related to blood pressure?
Think of it as like a shower head. The more you turn up the dial (blood pressure), the stronger the water shoots out of the head (coronary perfusion rate).
Which imaging technique is used to determine cardiac or cerebral perfusion plus brain imaging for epilepsy dementia and recurrent brain tumors?
PET
Coronary perfusion pressure?
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
What is transmural perfusion pressure?
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
What is cerebral blood flow regulated by?
Cerebral pressure auto regulation, adenosine receptor mechanism, nitric oxide.
What is cerebral hypertension?
unusually high blood pressure in your brain
Intracranial pressure in presence of hyperventilation?
Goes down. Hyperventilation "blows off" carbon dioxide (CO2), lowering the blood CO2 levels; this causes vasoconstriction (narrowing of the blood vessels) resulting in a lower blood volume in the brain and a slight drop in intracranial pressure. It is a temporary measure, however, and even though it lowers intracranial pressure it may make brain injury worse, because it reduces cerebral perfusion (the flow of blood to the brain.)
What is a nursing diagnosis for SVT?
Risk for decreased cardiac output related to altered electrical conduction Ineffective tissue perfusion: cerebral related to interruption of cerebral arterial flow secondary to decreased cardiac output Anxiety related to change in health status Ineffective health maintenance Risk for injury
