- 4) A) Calculate the Systolic Pressure of a 65 years old man if the diastolic blood pressure is 90 mmHg and stroke volume of 70 ml/beat. Total Peripheral Resistance is 19mmHg.min/L. Assume person is healthy and has a normal heart rate. B) Calculate Left ventricular end-diastolic volume (LVEDV) when the mean ejection fraction is 80 % ?Given the following information, calculate cardiac output: R-R interval = 0.6 second, EDV = 160 mL, ESV = 30 mL * 7.0 L/min 10.0 L/min O 13.0 L/min O 15.0 L/minGiven heart rate of 95 beats per minute, blood pressure of 125/90 mmHg, 0.2 mL O₂/mL systemic blood arterial oxygen content, 0.1 mL O₂/mL pulmonary arterial oxygen content, and 400 mL O₂/min oxygen consumption. Based on the information, calculate the i) stroke volume. and ii) total peripheral resistance. Show your work.
- 1) Cardiac output of a man is 6,3 l/min in the state of rest, body surface —1,8 m2. Calculate cardiac index, and estimate its value.59. A 20-year-old woman is participating in a study of skeletal muscle blood flow during dynamic exercise. A phonocardiogram is used to establish the timing of the cardiac cycle. In the resting skeletal muscle of this patient, the time of peak blood flow is most likely to occur during which of the following periods? A) Between S, and S₂ B) During S, C) During S₂ D) Immediately after S₂ E) Immediately before S,The cardiac output of 70-year-old man at rest is 5.5L / min; mean HR is 85 bpm. Left ventricular end-diastolic volume (LVEDV) is estimated to average 85 ml. What is the mean ejection fraction?
- Name three mechanisms that can increase cardiacoutput.Calculate %HRR for an individual (63 years old) who has a heart rate of 140 during running. The resting heart rate of this individual is 60 (HRmax= 208-0.7* age).List the directional changes that occur during exercise for therelevant cardiovascular variables?
- List the abbreviations and normal ranges of the following hemodynamic values directly measured by means of the pulmonary artery catheter: central venous pressure, right atrial pressure, mean pulmonary artery pressure, pulmonary capillary wedge pressure, and cardiac output.60) If the TV=50 and the ERV = 100 and the IRV = 75 and the RV = 200, what is the VC? Group of answer choices 175 425 150 125 225 61) Referring to the Cardiac Output formula, which value is most important in determining the cardiac output for an individual who is not in good shape? Group of answer choices Heart Rate End-diastolic volume Stroke Volume End-systolic volume 63) Carbon monoxide binds to hemoglobin _____times as strongly as oxygen does. Group of answer choices 25 200 50 100 2 64) When exercising, Starling’s Law comes into effect. Constantly contracting muscles will increase the venous return to the heart. Which of the following will be true in this case? Group of answer choices Local constriction of precapillary sphincters that control blood flow to the exercising muscle Decrease in Heart Rate Dilation of blood vessels that go to the digestive organs Decrease in the diameter of blood vessels to the exercising muscles Increase in…A person has an ejection fraction of 54% and an EDV of 130 mL. a) what is their stroke volume b) if they have a heart rate of 65 beats per minute, what is the cardiac output? c) If they increase their ED to 170 mL, what do you expect might happen to their ejection fraction (improve, stay the same or get worse)? Why- be complete in your answer. d) What law is this? e) How might the EDV be increased? Give at least one mechanism in detail
