Tissue perfusion refers to the process of delivering blood to the capillary beds in tissues. This is essential for providing oxygen and nutrients to cells while removing waste products. Adequate perfusion is crucial for maintaining healthy tissue function and overall body homeostasis. Factors affecting tissue perfusion include blood pressure, blood volume, and the health of the cardiovascular system. Conditions such as shock, heart failure, or vascular diseases can impair perfusion, leading to tissue damage or dysfunction. Monitoring and managing tissue perfusion is vital in medical settings to ensure proper organ function and patient recovery.
