[Correlation of the magnitude of fetal movement associated fetal heart rate accelerations, amplitude of "classical" accelerations and transcutaneous fetal oxygen partial pressure].
An attempt is made to provide non-empirical evidence of the "classical" amplitude of sporadic fetal heart rate accelerations of 15 bpm. Sporadic, fetal movement associated fetal heart rate accelerations are generally regarded as an indication of fetal wellbeing. A minimal amplitude of 15 bpm with unknown duration of the associated fetal body movement seems to be a prerequisite to establish an unimpaired fetal condition as reliably as possible. Including the "classical" acceleration amplitude in a ratio from the acceleration amplitude and associated fetal body movement and comparison of these calculated values with a total of 3851 actual ration from acceleration amplitudes and durations of associated body movements of 175 normotrophic and 72 hypotrophic fetuses showed that only a hypothetical acceleration amplitude of 15 bpm yields ratios which correspond to the actual values of unimpaired fetuses. There is a significant positive correlation between the actual ration and the transcutaneous basal fetal partial pressure of oxygen during birth.
