Lungs Left side of heart pumps... simultaneously to body Septum wall that separates two pumps atrioventricular valves separate atria and ventricles heard at apex, located at bottom of heart: 5th rib intercostal space Apical pulse is also called Mitral area/PM/Apex Right AV valve = tricuspid valve, 5th intercostal space at left sternal border Left AV valve = Mitral valve, 5th intercostal space at left midclavicular line Semilunar (SL) valves bet...

___ is calculated by multiplying the heart rate in beats per minute (beats/min) by the stroke volume (volume of blood ejected during systole) in liters per beat ~ Cardiac output The factors that determine ___ are (1) preload, (2) afterload, (3) myocardial contractility, and (4) heart rate. Preload, afterload, and contractility all affect stroke volume ~ cardiac output ___ is the volume and pressure inside the ventricle at the end of diastole Described in two ways •ventricular end-...

Indication for arterial line placement? -Answer- Hemodynamic monitoring Multiple blood samples Diagnostic or interventional radiology procedures Continuous cardiac output monitoring What test must be preformed prior to an arterial line placement? -Answer- Allen's test How often should a fast flush test be preformed? -Answer- Every 8 hours After blood draws If the hemodynamic status changes When changing tubing What are the most common sites for arterial line insertion? -Answer-...

cardiac output (CO) Correct Answer-volume of blood ejected from ventricle per minute (SV x HR) cardiac index Correct Answer-(CI) is sometimes used instead of cardiac output bc the cardiac output varies in people i. =Cardiac output divided by body surface area stroke volume (SV) Correct Answer-volume of blood ejected from the ventricle during on contraction,systole (EDV-ESV ejection fraction- Correct Answer-the fraction of EDV ejected from the ventricle during systolic contraction EF= S...

Ventricular filling is ____% passive and ____% active Ans- 80% passive 20% active from atrial contraction SA node impulse to AV node is shown as what on an ECG? Ans- P-R interval At the end of diastole the right ventricle contains _______ amount of blood Ans- 150ml S1 = S2 = Ans- AV Valves - S1 Semilunar - S2 QRS = Ans- Ventricular depolarization + co

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...

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...
