Hemodynamic Parameters Value Norms/Information _____________________________________________________________________________________ RAP/CVP 1-8 mmHg PAP 15-26 mmHg systolic 5-15 mmHg diastolic 8-12 mmHg mean PCWP 4-12 mmHg SVR 800-1200 dynes/sec/cm-5 PVR 20-120 dynes/sec/cm-5 EF 60-70% C.O. 4-8 L/min---HR X Stroke Volume C.I. 2.5-4 L/min/m2 ---formula C.O. / BSA SV Stroke volume normally is 70-80 ml Stroke volume is influenced by preload, contractility, and afterload Preload filling pressure exerted by the volume of blood in ventricles prior to systole (end-diastole) measured as RAP/CVP for the right ventricle measured as PCWP for the left ventricle Afterload resistance that the ventricles must overcome to eject blood forward Into the pulmonary arteries (right ventricle) and aorta (left ventricle). SVR is the measure of afterload for the left ventricle PVR is the measure of afterload for the right ventricle Compliance of the ventricles is the ability to stretch If compliance decreases-ventricle is stiff-and the pressure inside ventricle will increase with less blood volume Contractility

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
