Circulating blood volume

これは何か

Blood volume is the amount of blood in the circulation. Body systems detect changes in volume and reflect them through arterial pressure changes.^[1]

なぜ重要か

More circulating volume fills the vascular system more; too little volume leaves less fluid for the heart to pump and less pressure to maintain.^[1,2]

異常値が生じる根本原因

• Core relation: More retained sodium and water expands circulating volume and loads the arterial system; volume loss reduces venous return, pumped flow, and pressure support.^[1,2]

どの判断に影響するか

• It links kidney fluid balance, arterial pressure, swelling, dehydration, shock, and medication context.^[1]

解釈上の注意

• Routine blood pressure does not directly measure circulating blood volume.^[1]
