One hemodynamic benefit of intra-aortic balloon therapy is: A) Balloon inflation prevents right to left shunt B) Balloon deflation increases coronary artery perfusion C) Balloon inflation optimizes aortic valve performance D) Balloon deflation decreases left ventricular afterload - D) Balloon deflation decreases left ventricular afterload Which of the following hemodynamic profiles would benefit from aggressive fluid administration, pressors and antibiotic therapy? A) RAP 1, PAOP 4, SVR ...

HR x SV= CO CORRECT ANSWER-what is the calculation for cardiac output?*** 1) preload 2) afterload 3) contractility CORRECT ANSWER-what are 3 things that the SV is dependent upon? 1) CVP; right ventricular 2) PAOP (pulmonary artery occlusive pressure); left ventricular CORRECT ANSWER-the preload affects what two measurements of the heart? 1) PVR (pulmonary vascular resistance); right ventricular 2) SVR (systemic vascular resistance); left ventricular CORRECT ANSWER-the afterload affe...

Tx to decrease preload - -Diuretics -Dilators (nitrates, nitroprusside, morphine) Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the AV valves close, just prior to ejection -As preload increases, SV and CO will increase up to a point -Too high of a preload may lead to heart failure -Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities Cardiac output equation - CO = HR x SV Components of str...

Hemodynamics CCRN Latest Update with Certified Solutions Cardiac output equation CO = HR x SV Components of stroke volume Preload Afterload Contractility Preload components CVP (right ventricular) - central venous pressure PAOP (left ventricular) - pulmonary artery occlusive pressure Afterload components PVR (right ventricular) - pulmonary vascular resistance SVR (left ventricular) - systemic vascular resistance Normal cardiac output 4-8L/min CI -Cardiac index -take into account body surfa...

What value reflects right ventricular preload? - CVP or RA pressure In hypovolemic shock, does SVR increase or decrease? - increase CVP and PAOP are a measure of preload or after load? - preload Heart rate x stroke volume =? - cardiac output Stroke volume is dependent on what three concepts? - preload, contractility, and after load PAOP is a measure of which ventricle? - left SVR measures which ventricle? - left PVR measures which ventricle? - right PVR and SVR are a measure of preload o...

Cardiogenic shock: A. BP 96/54, CI 1.8, PAP 54/26, PAOP 10 B. BP 84/52, CI 1.9, PAP 32/18, PAOP 12 C. BP 82/48, CI 1.8, PAP 48/28, PAOP 18 D. BP 86/46, CI 2.0, PAP 28/14, PAOP 12 -:- C. BP 82/48, CI 1.8, PAP 48/28, PAOP 18 Following anterior wall MI, pt develops dysfunction of papillary muscle of mitral valve. There are large V waves on PAOP waveform. What is likely the cause? A. aortic regurg B. acute pulmonic regurg C. acute tricuspid regurg D. acute mitral regurg -:- D. acute m...

The patient has a right, mid and lower lobe pneumonia. Which of the following is an appropriate intervention for the patient? A) Provide fluids and expectorants B) Maintain in supine positions C) Hold enteral nutrition D) Avoid turning to the right side -:- D) Avoid turning to the right side Gravity will increase perfusion to the dependent lung tissue. The "good" lung in this case is the LEFT side. Turning the patient to the right may precipitate hypoxemia by increasing perfusion ...

Cardiac output CORRECT ANSWER *Heart rate x Stroke volume* Stroke volume is dependent on the *preload, afterload, and contractility* of the ventricles of the heart -*Preload*: CVP (right ventricle), PAOP (left ventricle) -*Contractility* -*Afterload*: PVR (right ventricle), SVR (left ventricle) Normal cardiac output CORRECT ANSWER 4-8 L/min -If critically low, BP will decrease Cardiac index CORRECT ANSWER amount of blood pumped out of heart per minute per sq meter of body mass. Ta...
