Webtral nervous system. During labor, in the presence of a gradually-evolving hypoxia associated with the onset of metabolic acidosis, FHRV may be reduced. However, if a fetus is exposed to rapidly-evolving hypoxia, it may not have sufficient time to release catecholamines and the per-fusion of central organs can be impaired. WebJan 1, 2016 · Cardiotocographic (CTG) analyses of fetal baseline heart rate, accelerations, variability and decelerations. Physiology-based CTG interpretation identifies the following types of hypoxia: acute, subacute, gradually evolving and chronic.
