FIZZ ICU

Right ventricular MCS must address the three major problems: decreased oxygen delivery, decreased perfusion, & increased oxygen consumption.

LV support devices should be initiated with the goal to reverse the hemodynamic abnormalities and fully support the patient.

MCS management addresses the hemodynamic problems of decreased oxygen delivery, decreased perfusion, and increased consumption.

Cardiogenic shock occurs when there is not enough oxygen delivery due to decreased cardiac output related to the heart.

Understanding the hemodynamics and pathophysiology of cardiogenic shock allows you to understand the treatment.

Left ventricular outflow obstruction (LVOTO) can be seen in the ICU due to hypertrophic cardiomyopathy and SAM or SAM by itself.

Learning how to medically manage valvular disorders is an important part of working in a Cardiac ICU.

Treating LV systolic dysfunction at the physiological level is extremely important since patients are not all the same.

Afterload is defined as the load or resistance the heart must overcome during systole.

Contractility is the strength of the contraction of the myocyte independent of preload and afterload.

When looking at preload issues it is important to decide if there is a volume problem or pressure problem.

Definition: the stretch of the cardiomyocytes at the end of diastole.

Afterload is defined as the resistance the heart must overcome during systole.

Right ventricular contractility is defined as the performance of the ventricle at a given filling volume and systolic pressure.

If a patient is hypervolemic and developing an AKI, it is usually due to volume overload and renal venous congestion.

1897: The first four –tropies were described: inotropy, chronotropy, dromotropy and bathmotropy. In 1982 lusitropy was described.
