[Controlled ventilation in a patient with acute exacerbation of a chronic myeloic leucaemia. A case report (author's transl)].

High counts of myeloid cells lead to erroneous results of blood gas measurements due to high rate of metabolism. This in vitro metabolism simulates hypoxaemia in the common chemical analyses. Therefore problems in the correct interpretation of blood gas measurements during controlled ventilation may arise, demonstrated in our case report of a patient with chronic myeloid leucaemia in acute stage. Immediate blocking of blood oxydative phosphorylation in the sample withdrawn is necessary in order to determine actual values which are important for adequate artificial ventilation.
