What is Hemodynamic Monitoring? - Measurement of pressure, flow and oxygenation within the cardiovascular system. What are values that are measured in the ICU with Hemodynamic Monitoring? - Systemic and Pulmonary arterial pressures, central venous pressures (CVP), pulmonary artery wedge pressure (PAWP), CO/CI, SV/SV index (SVI) and O2 saturation of the hemoglobin of arterial blood (SaO2) and mixed venous oxygen saturation (SvO2). What is Cardiac Output? - The volume of blood in liters pump...

What is the equation for cardiac output? - CO = HR x SV What is preload? - the heart is being stretched out What does preload reflect? - how much fluid is in the heart What is afterload? - resistance the ventricle must overcome to eject blood Example of increased preload - CHF Example of increased afterload - hypertension What is blood pressure? - force of blood against vessel walls What is systolic blood pressure? - amount of pressure generated by the left ventricle to distribute blood ...

1 PCCN EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answer: 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 ...

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - Answer 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 cor...

PCCN Cardiac Exam 127 Questions with Verified Answers Which of the following is the outermost lining of the heart? A. Endocardium B. Myocardium C. Transcardium D. Pericardium - CORRECT ANSWER D. Pericardium "Endo" meaning "within" is associated with the innermost lining of the heart, so eliminate A. The myocardium is associated with the heart's middle layer, so eliminate option B. The "transcardium" is somewhat of a contrived term, so eliminate C as well. The prefix in pericardium...
