Preload refers to Study guides, Class notes & Summaries

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known as coronar...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...

Pulmonary edema - ACCURATE ANSWERS Nitroglycerin - reduce preload loop diuretic - promote diuresis and venodilation morphine - reduce anxiety ACE inhibitors - reduce afterload Ventricular tachycardia - ACCURATE ANSWERS 3 or more ventricular contractions in a row at a rate of 100-200 bpm. Defibrillate if patient is unconscious or unstable Cardiac tamponade - ACCURATE ANSWERS S/S: decresed chest tube drainage, muffled heart sounds, tachycardia, pulsus paradoxus, and decreased urinary o...

Heart rate less than 60 When is nitroglycerin not advised to be administered? if the systolic blood pressure is less than 100 Wher...

What is perfusion? - Answer Blood flow through the arteries and capillaries to help deliver nutrients and oxygen to the cells in the body What is systole? - Answer - Phase in which the ventricles contract causing pressure that closes the mitral and tricuspid valves which prevents blood from flowing back into the atria - The pressure then causes the aortic and pulmonic valves to open causing ejection of the blood into the aorta and pulmonary arteries What is ejection fraction? - Answer...

RCIS Mock Exam Latest Update with Verified Solutions In normal fetal circulation the path of oxygenated blood returning from the placenta passes though several fetal shunts. One of these normal fetal pathways between the aorta and PA can be described as a: a- L>R shunt termed the PDA b- R>L shunt termed the PDA c- L>R shunt termed the foramen ovale d- R>L shunt termed the foramen ovale the PA-AO shunt is the PDA and its right to left. When the left heart pressure begins to exceed...

The pressure in the arterial system that the heart must overcome to pump the blood - -b. The volume of blood entering the right side of the heart Preload is the volume of blood that enters the righ...
