What is cardiac output? Volume of blood ejected by the heart in one minute What is the cardiac output equation? cardiac output = heart rate x stroke volume what is cardiac reserve? the difference between a person's maximum and resting cardiac output- increase with fitness, decrease with diseas...
Cardiac output (CO) in 12 infants of diabetic mothers (I DMs) and in 20 normal neonates (control group) was estimated evaluating blood velocity in ascending aorta, using a gated pulsed Doppler velocimeter with a 5MHz transducer positionated in the suprasternal nocth. CO (mL/min/Kg) was ...
Fick equation (cardiac output formula) The most common formula used for determining the cardiac output is the Fick equation. It states that: CO=VO2 / (Ca−Cv)CO=VO2 / (Ca−Cv) where: VO2VO2 stands for the oxygen consumption of pure gaseous oxygen (in mL/minute); CaCa is the co...
