How does high Fetal catacholamines cause acidosis?
Acidosis is due to fetal hypoxia. Catecholamines are released in response to hypoxia. The function of high catecholamine concentrations has been shown to control fetal circulation during hypoxia, to maintain glucose supply to the heart and brain, and to prepare the lung for ventilation. So it may be said that fetal plasma catecholamine surge at birth is essential to neonatal adaptation.
