- Throughout the development of prosthetic heart valves, how might application of nanotechnology be used to improve the strength of the prosthetic heart valves and reduce complications and failures? Discuss.John black is a 58 year old mechanic that has prosthetic heart valves and is on warfarin. He is coming for his teeth cleaning and the dentist ask his physician about antibiotic prophylaxis. According to the AMA, what are the high risk cardiac conditions where antibiotic prophylaxis is needed? If he needs an antibiotic what classes are acceptable and which are not? Need complete solution of question Be sure your answer is unique and correct ..... If u copied from internet or chegg I report to barlteyby .thanksWhat are drug eluting stents and why are they used? What is the difference between cardioversion and defibrillation? What effect does albumin have on the circulatory system?
- 4.4. On the circulatory system, what are the correct statements? PHYSIOLOGY_advanced (OJO) Pacemaker cells of the heart are neurons with a stable resting membrane potential. Pacemaker cells of the sinus node, located at the left atrium, determine the heart beat frequency. Cardiac output is a function of the heart beat frequency and the stroke volume. The Frank-Starling mechanism allows coupling of the venous return with the stroke volume. Within each capillary bed there is a net loss of liquid to the extracellular space; this imbalance depends on the hydrostatic pressure and the colloid osmotic pressure gradients.The standard EKG consists of 10 sensors that record 12 leads of the heart’s electrical activity from different angles, allowing for a thorough three-dimensional interpretation of its activity. This is transmitted by the electrodes to the equipment to be interpreted and is used to diagnose cardiac medical conditions. In case of an abnormal EKG, the second step would be to use a Holter monitor. How would you explain to your classmates how to perform an EKG (steps)? Where will you place the electrodes when performing and EKG? Why? What are the different lead types, connections, and placements? When you conclude an EKG, what are the different components that you need to observe and confirm before you disconnect the patient? Can you explain the difference between normal, abnormal, and artifacts? What is a Holter monitor? Under what circumstances would one be ordered for a patient? How do you use a Holter monitor? Educate a patient: What you will do before, during, and after an…1. You are a lead engineer in a cGMP facility that develops and delivers tissue engineering constructs for tissue regeneration. You have been asked to develop an injectable tissue engineering solution for regenerating heart tissue following myocardial infarction. Describe an injectable tissue engineering solution to regenerate the damaged heart tissue by considering the following and give a brief explanation for your choices: i) Description of large animal model for myocardial infarction, including animal and method
- My Steve Dixon, a 55 year old male, has been admitted to the hospital for a heart attack (myocardial infarction). The Mr. Dixons cardiologist has ordered the nuclear medicine department to obtain a scan to measure to function of his right and left ventricles post–myocardial infarction. What is the name of the nuclear medicine scan being performed?What are the difference between contractile cells of the heart and electrical cells responsible for generation and conduction of impulses. Why is the cardiac action potential propagated more slowly in an AV node cell than in an atrial or ventricular myocyte? How are the channels and ions that are responsible for depolarization and repolarization work? How can be AV conduction affected by hypokalemia?*DO NOT COPY AND PASTE THE ANSWER THAT CHEGG HAS FOR THIS QUESTION. I HAVE ASKED THIS QUESTION AND THE "EXPERT" COPIED AND PASTED THE ANSWER FROM CHEGG. PLEASE ACTUALLY SOLVE THIS PROBLEM, OR I'LL JUST HAVE TO CANCEL MY BARTLEBY SUBSCRIPTION. Hello, please answer the following Physiology question completely and correctly. Thank you. Physiology Question Based On Attached ECG: "On the pressure curve label the stretches on the ventricular curve that represent the 5 different phases of the cardiac cycle. Also, label where they are closing. Where would the AV valves be opening and where would the semilunar valves be opening?"
