WebShunt calculation (Qp:Qs ratio) using the Fick principle. The above equation requires measurement of the end-pulmonary-capillary oxygen content (Cc O2) which is difficult to obtain and it is assumed to be equal to the alveolar oxygen content. This is based on the assumption that, if an alveolus is receiving air, then it is perfectly oxygenated WebThe 3 main approaches are the Fick method, dye dilution, and thermodilution techniques. The latter 2 are based on the use of indicators that indirectly quantify blood flow. ...
