a,b, Exemple case of StO2 and HbO2 during maternal hyperoxia. c,d, Averaged placental rStO2 (purple), rHbT(blue), and rHbO2 (red) for NPO participants (n = 15) and for participants with APO (n = 9). e,f, Averaged placental rStO2 (purple), rHbT(blue) and rHbO2 (red) for NPP participants (n = 16) and for participants with MVM (n = 8). Shaded regions represent the standard error. The cohort-averaged rStO2 and rHbO2 exhibit a significant increase during maternal hyperoxia for the NPO and NPP groups, but a blunted response for the APO and MVM groups.
