Webwith the direct Fick measurement (which requires a directly obtained measurement of oxygen uptake) [3]. The indirect Fick technique, which estimates the amount of oxygen uptake, may also be employed for determination of cardiac output. For this purpose, SvO 2 is measured while the tip of the catheter is in the
WebCalcific AS was initially believed to be a passive disease associated with the wear and tear of valve tissue due to aging.
