Acute maternal hyperoxygenation protocol: consensus opinion from the Fetal Heart Society.

The article discusses the consensus opinion from the Fetal Heart Society on the acute maternal hyperoxygenation (MH) protocol. Acute MH testing can help understand fetal pulmonary vascular reactivity and simulate postnatal circulatory shifts. The document provides a standardized approach to conducting acute MH testing, including indications, timing, oxygen administration, fetal echocardiography assessments, and interpretation of findings. The consensus opinion aims to guide fetal cardiac centers interested in implementing acute MH testing for clinical and research purposes. [Extracted from the article]
