hemodynamic changes

Hemodynamic changes refer to how blood moves and pressures within the body’s circulatory system. They involve factors like heart rate, blood vessel size, and blood volume, which influence blood flow and pressure. For example, if blood vessels constrict, blood pressure increases; if they dilate, it decreases. The heart’s pumping strength also affects how much blood is circulated. These adjustments help maintain proper oxygen and nutrient delivery to tissues. Hemodynamic changes occur naturally or in response to illness, stress, or injury, helping the body adapt to different needs or challenges.
