Die Sauerstoffgehaltsbestimmung: Vergleichsmessung zwischen dem neuen Oxystat®-Photometer und dem Lex-O₂-Con®

Abstract

The Oxystat-photometer (Fa. Andos) is a new instrument for measuring of oxygen content and haemoglobin of blood. Using specific agents oxygen and haemoglobin can be registered in small cuvettes. The principle of measurement is photometry. Additionally O2-saturation can be calculated. In 139 experiments we checked the reliability of the Oxystat-photometer in comparison to the Lex-O2-Con (Lexington Instruments Corporation). High significance could be demonstrated (r = 0.96). There was a range from the control value below 5%. Following investigations using calculation, results could be confirmed.
