Comparative StudyComparison of calculated and measured mixed venous oxygen saturation in critically ill patients.
According to the Fick principle the calculation of cardiac output and shunts is based on the exact determination of oxygen saturation. In this study an intraindividual comparison of two frequently applied methods was done. ⋯ Especially when handling with lower oxygen saturations, calculation of saturation with an automatic gas analyzer leads to overestimated values. The Fick principle can only be applied for hemodynamic calculations when oxygen saturation can be determined by an easy and correct method.

[Establishing a quality assurance system in transfusion medicine exemplified by the Heidelberg University Blood Bank].
The 'Zweite Verordnung zur Anderung der Betriebsverordnung für pharmazeutische Unternehmer vom 13. Juli 1994' requires a quality assurance system for the manufacturing of blood products. ⋯ The concept underlying the quality assurance system of the university blood bank at Heidelberg allows continuous quality improvement in transfusion medicine; moreover, it offers the chance to integrate quality assurance in transfusion medicine in an interdisciplinary, patient-orientated, not only regional concept of quality assurance.
