[Changes in acid-base and blood gas parameters in relation to storage time and temperature].

The changes of the acid-base- and blood gas parameters were continuously measured under different storage conditions by means of the blood-gas automaton ABL 1 with the help of 40 blood tests of various patients. The results are discussed and a recommendation for practice is given. Apart from the necessary immediate determinations (without any restriction) in the hermetically closed blood tests transported or stored at 0--5 degrees C even three hours after blood taking analyses were got which could still be used clinically. In these cases by the clinicians only a decrease of BE of 2 mmol/l of blood should be taken into consideration. The result render possible a greater usability of the imported blood gas automatons.
