Guiding Principles for Organizational Design. 1  Ultimate principle: Make it easy and motivating for people to collaborate, innovate, and achieve. â Organizational design is the means for creating a community of collective effort that yields more than the sum of each individualâs efforts and results.
Ejection fraction is calculated by the amount of blood pumped out of the heart with each beat divided by the amount of blood in the heart at its fullest. In other words, ejection fraction measures what percent of the blood in the heart is pumped out when the heart beats. A normal range for ejection fraction is 65 percent, plus or minus 12. That means that normal, healthy hearts only pump about 65 percent of the blood out of their heart with each beat. There are multiple ways to measure ejection fraction, including: Echocardiogram (ultrasound of the heart)
But more importantly, the MUGA scan gives an accurate and reproducible means of measuring and monitoring the âejection fractionâ of the cardiac ventricles. The left ventricular ejection fraction (LVEF) is an excellent, and the most commonly used, measure of overall cardiac function. The ejection fraction is simply the proportion of blood that is expelled from the ventricle with each heart beat. So, for instance, if the left ventricle ejects 60% of its blood volume with each beat, the LVEF is 0.6.
