The patient cole is sitting on a chair. Suppose he raises his arm for a blood pressure measurement, with the cuff placed 10 cm below his heart. (a) How much of an error (difference in pressure) in mmHg does this introduce in the measurement? Assume that the blood is static for simplicity. The density of blood is 1050 kg/m3. AP = (b) If the systolic & diastolic blood pressures from the patient's heart is 125 & 85 mmHg, what will the cuff's pressure reading be? & (c) Describe a way to measure cole blood pressure accurately. 3
Blood Flow (BF)= (diff. in) Pressure (P) /Resistance (R) Assign these numbers to the equation above: If 6/3=2, when you increase 3, what happens to 6 in order to get 2 to stay the same?
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.
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/min
A 43-year-old woman has congestive heart failure after a myocardial infarction. Before the myocardial infarction, she had a cardiac output of 5 L/min and a right atrial pressure of 0 mm Hg at rest. The solid curve in the graph shows the relationship between right atrial pressure and cardiac output in a normal heart. Which of the following lettered points best represents the change in this relationship after the development of congestive heart failure?
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?
In the same BP measurement= 120/80, what is the arterial pressure when the left ventricle is at the peak of its contraction? Choices: 120804093
Hemodynamics are the dynamics of blood flow. Can the Bernoulli's equation be used to study hemodynamics in the cardiovascular system? Why or why not? You should discuss all four of the assumptions of Bernoulli's equation when answering this question.
