Best Answer

Ventilation is actually the object of breathing itself. When the lungs take in oxygen. It can be made difficult by injuries such as broken ribs or anything that makes breathing painful.Perfusion is when the red blood cells carry oxygen throughout the body to adequately distribute it to body tissues. It is a continuous process performed by the cardiovascular system.

What does the medical abbreviation V-P scan mean?

A V-P scan is a ventilation/perfusion scan. Sometimes it's called a V/Q scan as well. It is a radiology study to check how well air is getting into the lungs (ventilation) and how well blood is getting to the lungs (perfusion).

Coronary perfusion pressure?

What is the difference between ventilation and breathing?

Breathing is the process of taking air into and out of the lungs, while ventilation refers to the movement of air in and out of the lungs to facilitate gas exchange. Ventilation involves both breathing (inspiration and expiration) and the distribution of air within the lungs.
