What is preload Study guides, Class notes & Summaries

minimum urine output for adult 0.5mL/kg/hr ADH (antidiuretic hormone) - water retainer - vasoconstrictor (also called Vasopressin) - produced by hypothalamus - store and released from posterior pituitary ADH pathway - hypothalamus senses low blood volumed and increased serum osmolality - signal pituitary to release ADH - ADH causes kidney to retain water - water retention increases blood volume and decreases serum osmolality ANP (atrial natriuretic peptide) -...

What is the equation for cardiac output? - CO = HR x SV What is preload? - the heart is being stretched out What does preload reflect? - how much fluid is in the heart What is afterload? - resistance the ventricle must overcome to eject blood Example of increased preload - CHF Example of increased afterload - hypertension What is blood pressure? - force of blood against vessel walls What is systolic blood pressure? - amount of pressure generated by the left ventricle to distribute blood ...

how does inflammatory process contribute to reperfussion injury? Correct Answer: as oxygen is reintroduced it comes in contact with damaged proteins triggering inflammatory response how does oxidative process contribute to RI?
