Difference between perfusion and oxygenation

WebMar 24, 2011 · Oxygen therapy is the term we use for the clinical use of supplemental oxygen. It's indicated in patients with acute hypoxemia (PaO 2 less than 60 mm Hg or SaO 2 less than 90%) and those with symptoms of chronic hypoxemia or increased cardiopulmonary workload. Oxygen is also given to help with the removal of loculated air … WebWhat is blood perfusion? Blood perfusion is the local fluid flow through the capillary network and extracellular spaces of living tissue. It is characterized as the volumetric flow rate per volume of tissue. Blood perfusion is vital for normal tissue physiology and is responsible for the transport of oxygen, nutrients, and waste products.
