Arterial hemodynamics - Study guides, Class notes & Summaries

the study of blood moving through the circulatory system - hemodynamics indicates the volume of blood moving during a particular time - flow (also called volume flow rate) units for flow - L/min indicates the speed of a fluid moving from one location to another - velocity units for velocity - cm/s 3 basic forms of blood flow - 1. pulsatile 2. phasic 3. steady occurs when blood moves with a variable velocity due to cardiac contraction, and appears in arterial circulation - pulsatile flow...

What is hemodynamics? - The study of blood flow or circulation Is hemodynamic monitoring non-invasive? - No, it is invasive. What types of information can be obtained with bedside hemodynamic monitoring? - vascular capacity, circulating blood volume, pump effectiveness, tissue perfusion, and physiologic response to treatment What are the indications for hemodynamic monitoring? - Decreased cardiac output, deficient fluid volume, excess fluid volume, and ineffective tissue perfusion What is...

What is the max acceptable venous line pressure? A. 40 mmHg B. -40 mmHg C. 120 mmHg D. -120 mmHg - Answer B. -40 mmHg An advantage of continuous warm blood cardioplegia is: A. increased oxygen delivery. B. significantly decreased myocardial oxygen tension. C. a shift of the oxygen dissociation curve to the left. D. lower myocardial oxygen consumption. - Answer A. increased oxygen delivery. Intra-aortic balloon augmentation is contraindicated in patients with: A. prosthet...

What are hemodynamics? - >>physical principles of blood flow based on pressure and resistance How are hemodynamics used clinically? - >>they are a diagnostic tool that helps us gather more data about our patient How is pressure calculated? - >>blood flow times resistance If either blood flow and/or resistance goes up, what happens to pressure? - >>it goes up If blood volume increases, what happens to pressure? - >>it increases How is arterial pressure monitor...

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...

An advantage of continuous warm blood cardioplegia is: A. Increased oxygen delivery B. Significantly decreased myocardial oxygen tension. C. A shift of the oxygen dissociation curve to the left. D. Lower myocardial oxygen consumption - Answer increased oxygen delivery Intra-aortic ballon augmentation is contraindicated in patients with: A. prosthetic aortic valves B. aortic insufficiency C. ventricular septal defects D. peripheral atherosclerosis - Answer aortic insufficiency W...

A client with a history of right-sided heart failure lives in a long-term care facility. In the daily assessment, the nurse is required to record the level of this client's peripheral edema. Which would be the main area for examination? Correct response: feet and ankles Explanation: Edema occurs when blood is not pumped efficiently or plasma protein levels are inadequate to maintain osmotic pressure. When blood has nowhere else to go, the extra fluid enters the tissues. Particular areas ...

The advantage of continuous warm blood cardioplegia is: A: increased oxygen delivery B: significantly decreased myocardial oxygen tension C: a shift of the oxygen dissociation curve to the left D: lower myocardial oxygen consumption - correct answer A IABP augmentation is contraindicated in patients with: A: prosthetic aortic valves B: aortic insufficiency C: VSDs D: peripheral atherosclerosis - correct answer B When using a roller pump. aortic dissection caused by the aort...
