When a reduction in uterine blood -ow was maintained for 7 days, fetal oxygenuptake was sustained despite a sizeable decrease in oxygen delivery. In steady state, fetal oxygenuptake is equal to fetal oxygen consumption. The six-minute walk test predicts peak oxygenuptake and survival in patients with advanced heart failure. The values obtained were expressed as mol oxygenuptake/mg protein/30 min. In the analysis, we used the data from the best performance with the highest oxygenuptake. At haematocrits <16% or >48%, corresponding to a fetal oxygen delivery <0.6 mmol min71 kg71, oxygenuptake by the fetus decreased. However, even when fetal oxygen delivery was reduced by 50%, oxygenuptake was kept constant by a compensatory increase in fetal oxygen extraction. In most patients, the normal increase in oxygenuptake occurred during higher levels of exercise. Despite a rise in fractional oxygen extraction, fetal oxygenuptake fell by 43%. This involves exercising a patient on a cycle ergometer attached to 12-lead electrocardiography whilst measuring oxygenuptake and carbon dioxide production. Umbilical blood -ow could be reduced by almost half without in-uencing fetal oxygenuptake. This degree of cord compression was, however, associated with a fall in fetal oxygenuptake. Consequently, it accounted for a smaller proportion of total uterine oxygenuptake (28%) than during normal growth (53%). There was, however, a marked reduction in fetal oxygenuptake when oxygen delivery was decreased by more than 55% (to <0.5mmol min71 kg71). Upon reevaluation heart rate, respiratory rate, oxygenuptake, ventilatory equivalent for oxygen, end-tidal carbon dioxide tension and physiological dead space did not change significantly. The reproducibility and correlation between measurements of activity and oxygenuptake were also analyzed. Thus, under normal physiological conditions, the oxygen supply to the fetal lamb is approximately twice that needed to maintain an adequate fetal oxygenuptake. Survival and oxygenuptake in osmotically controlled storage. In the absence of these factors, both dormant and non-dormant seeds showed similar low levels of oxygenuptake.
