Cardiac Output

Question 1

what is the Frank-Starling relationship? what does it relate to?

Answer 1

the amount of blood that is ejected from the ventricle depends on the end-diastolic volume (EDV)

relates cardiac output with venous return (they are directly proportional)

Question 2

does volume work or pressure work require more oxygen? left or right ventricle and why? what exacerbates this?

Answer 2

pressure work

left ventricle because systemic pressure is greater than pulmonary

aortic stenosis or systemic hypertension

Question 3

what is the fick principle/equation?

Answer 3

CO= total O2 consumption/ (pulmonary vein O2 consumption - pulmonary artery oxygen consumption)
