Worldwide, uncountable arterial macropunctures and cannulations are performed for blood-gas analysis. The associated complications are accepted as inevitable. 8,000 arterial micropunctures performed under controlled conditions show that this sampling method is not only simpler but also less traumatic and less susceptible to errors of method. As these advantages are not countered by any disadvantages, microsampling is suggested for general use.

An ultrasound unit for hemolysis for an analytic device is presented which permits hemolysis without the need of a specific insonification chamber which is an unwanted discontinuity along the probe path. This is possible by direct insonification of a flexible tube which contains the flowing blood. The influence of ultrasound power, insonification time and coupling conditions on the result of hemolysis is investigated.
