What does the medical abbreviation CPP mean?
Cerebral Perfusion PressureCerebral Perfusion Pressure
What is a Myocardial perfusion scan used for?
does myocardial perfusion scan show blockage in heart system.
Which of the choices below does not involve tissue perfusion?
Tissue perfusion is the amount of blood that the tissues receive during circulation. When a person has decreased tissue perfusion, the tissues are receiving inadequate blood supply.
Exchange of gases?
perfusion
What is perfusion phase in medical terms?
The perfusion phase is the part of a contrast scan in which the contrast is moving into the blood vessels.
The circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs is?
Perfusion
What does perfusion refer to in physiology?
In reference to physiology perfusion is the process of blood being delivered to a capillary bed in the biological tissue. Normal levels of perfusion can be tested by looking at skin color or skin temperature.
Would pulmonary edema cause disruption in perfusion while diffusion would be normal?
it desrupt both perfusion and diffusion in lungs
What is ventilation perfusion coupling?
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
Can you have alcohol after a myocardial perfusion scan?
yes
What is high space shock?
Volume remains the sameTank (vessels) expandsHigh space shock goes by other names you may be familiar with, such as relative hypovolemia or distributive shock. In this form of shock, the fluid volume remains the same, but the vessels dilate causing poor perfusion and hypotension. Fluid can also shift from intracellular to extracellular space. This can be seen in neuogenic shock (spinal shock) where vessels lose sympathetic tone (which causes vasoconstriction), anaphylaxis, or sepsis. All of these forms of shock show hypotension that should be initially managed with fluid, but it is not due to true hypovolemia.
Can you have a myocardial perfusion scan after a cataract operation?
