[Ergo-oxytensiometry--recommendations on methodology and evaluation].

The purpose of this review is to provide recommendations for measurement and interpretation of ergooxymetry relevant to performance in out-patient departments. Ergooxymetry is the most suitable method for assessment of physical work capacity. The examination demands a distinct indication and knowledge of contraindications. On the basis of a standardized 3-step loading (VO2 = 1,050 ml/min, VO2 = 1,350 ml/min, VO2 = 1,650 ml/min; incremental loading without breaks; 6 min for each loading step) criteria for interpretation are given for PaO2, heart rate, arterial blood pressure and FEV1 respectively ROS.
