Hemodynamics norms


Total amount of blood volume in the venous system is? 64%
Venous return is the amount of blood volume returning to the? Right heart.
CI is CO based on? Actual body size.
End systolic pressure is? The amount of blood in the ventricle after ejection.
End diastolic pressure is? The amount of blood in the ventricle after filling.
Indexed measurements allow the normals to be standardized therefore account for the patients different body sizes. True.
Patients who develop A-fib or 3rd degree heart block, lose their atrial kick and? CO decreases.
Cardiac Tamponade Restricts the blood entering the heart.
Fick equation CO= VO2/C(a-v)O2 x 10
Right atrium pressure. (RAP) Measured with CVP or Swans.2 to 6 torr.
Right ventricle pressure. (RVP) Measured with Swans.20 to 30/2 to 6 torr.
Pulmonary artery pressure. (PAP) Measured with Swans.20 to 30/6 to 15 torr.Waveform has diacrotic notch.
Pulmonary capillary wedge pressure. (PCWP) Measured with Swans. 4 to 12 torr.
Ejection fraction. EF= SV/EDV If in the 30% range intolerance to exersise.
PAP looks at? lungs.
PCWP looks at? Left heart.
CVP looks at? Right atrial pressure or fluid levels. Norm 2-6 torr.
Systemic Artery Blood Pressure (SABP)looks at? Blood pressure thoughout the body.
Ventricular stroke work. Amount of blood ejected with each beat.
CVP norm? 2-6torr.
Cardiac Output QT norm? 4-8 L/M
Cardiac Index (CI) 2.5-4.5
Preload The stretch on the ventricle muscle fibers before contraction.
Afterload The resistance of external factors that oppose ventricular contraction.
Stroke volume is determined by? Preload, afterload, and contractility.
Preload is created by? End diastolic volume.
If there is no narrowing or dysfunction of the valve... Pressures in the atrium will be the same as in the ventricles at the end of diastole.
Atrial contraction is... 30% of cardiac output.
Afterloads two opposing factors? Tension and impedance.
Intrathoracic become more negative.(vacume effect) Increases filling and increases resistance to emptying of ventricles.
Increase in Ca causes? spastic heart.
Decrease in K+ and Na causes? Atrial fibrillation.
