WebCardiac output (CO) is a measurement of the amount of blood pumped by each ventricle in one minute. To calculate this value, multiply stroke volume (SV), the amount of blood pumped by each ventricle, by heart rate (HR), in contractions per minute (or beats per minute, bpm). It can be represented mathematically by the following equation: WebCardiac Outputis the product of Stroke Volume (SV) and Heart Rate (HR). Stroke volumeis determined by three factors: preload, afterload and contractility. Preloadis the initial ˜bre …

Web19 feb. 2024 · How Does Cardiac Output Affect Blood Pressure Cardiac output can be calculated by the stroke volume multiplied by the heart rate. Any factor that causes cardiac output to increase, by elevating heart rate or stroke volume or both, will elevate blood pressure and promote blood flow. Blood pressure is a measure of how much force is … WebCardiac output is a product of stroke volume and heart rate. iii. Stroke volume (SV) is volume of blood pumped out per ventricle per beat, which is normally about 70 ml. ADVERTISEMENTS: iv. The normal heart rate (HR) can be considered as about 70 per minute. In which case. Cardiac output = HR x SV. = 70 x 70 = 4900 ml.
