Study Notes
Perfusion Basics
- Perfusion refers to the system that delivers blood to tissues.
- Perfusion is measured as the rate of blood delivery to tissue, or the volume of blood per unit time per unit tissue mass.
Perfusion Unit
- The SI unit for perfusion is mL/min/100g (milliliters per minute per 100 grams).
Etymology
- The word "perfusion" is derived from the French verb "perfuser", which means "to flow through".
Health Consequences of Poor Perfusion
- Poor perfusion can cause health problems such as:
- Oxygen deprivation
- Nutrient deficiency
- Waste buildup
- Cellular damage
Purpose of Perfusion Tests
- The purpose of tests verifying that adequate perfusion exists is to:
- Identify potential health problems
- Monitor treatment effectiveness
- Ensure proper tissue function
