38: Hyperoxygenation in pregnancy exerts a more profound effect on hemodynamics than in a non-pregnant state

The hemodynamic effects of oxygen therapy are under recognized and the impact of hyperoxygenation (HO) on maternal hemodynamics is currently unknown. Using transthoracic bioreactance (NICOM), we sought to examine the effect of brief hyperoxygenation on cardiac index (CI), systemic vascular resistance (SVR), blood pressure (BP), stroke volume (SV) and heart rate (HR) in pregnant mothers during the third trimester as compared to those observed in a non-pregnant population subjected to the same period of hyperoxygenation.
