[Hypoxia, acidosis and nephrology]

In a survey the correlations between hypoxia, acidosis and nephrology are presented. In chronic oxygen deficiency the individual aspects concern the uncertainties of erythropoietin and the carotid-sinusoidal natriuresis stimulated by chemoreceptors. The effects of acute ischaemic hypoxic reactions are described with regard to the acute renal failure. The regulatory renal function of acidification and its disturbance in chronic renal insufficiency as well as the renotubular acidosis are discussed. Finally the authors enter the influence on the renal function during positive pressure respiration (e.g. for the purpose of the normalisation of the pulmonary gas exchange in acute respiratory insufficiency) as well as on reactions of the haemodialysis (bicarbonate and acetate dialysis) to the blood gas and acid-base metabolism, taking into consideration the pulmonary function.
