Hemodynamic Monitoring Exam With100% Correct And Verified Answers 2024
Cardiac Index (CI) - Correct Answer-2.2-4.0 L/min/m2
Stroke Volume Index (SVI) - Correct Answer-30-65
mL/beat/m2
PAWP (pulmonary artery wedge pressure) - Correct
Answer-6-12 mm Hg
-Assessment of left ventricular pressure/function
-Left ventricle preload (left ventricle end-diastolic pressure
CVP (central venous pressure) - Correct Answer-2-8 mm Hg
-It is the right ventricular preload
-Also known as right atrial pressure RAP
Preload - Correct Answer--The volume w/n the ventricle at
the end of diastole.
-The more a myocardial fiber is strecthed during filling, the
more it shortens during systole and the > the force of the
contraction.
Vendarsol
, -As preload increases, force generated in the subsequent
contraction increases and SV and CO increases.
-The > the preload, the > the myocardial O2 requirements
-The measurement is made of the peak pressure at the time of the
peak stretch (end diastole).
-This indicates the pressure in the blood vessels of the lungs or in
the blood returning to the heart.
Afterload - Correct Answer--The forces opposing ventricular
ejection.
-Includes systemic arterial pressure, the resistance offered by the
aortic valve, and the mass and density of the blood.
-SVR and arterial pressure are indices of left ventricular afterload.
-PVR and pulmonary arterial pressure are indices of right
ventricular afterload.
-Increased afterload often results in in a decreased CO and
increased O2 demand.
-CO can be improved and myocardial O2 needs reduced by
decreasing afterload.
Continous Arterial BP Monitoring Indication - Correct Answer--
Acute HPTN & HTN
-Respiratory failure
-Shock
