MODEL RELEASED. Newborn baby. Nurse administering oxygen to a newborn baby through a face mask to ensure that there is enough oxygen in the baby's tissues. This baby was delivered by caesarean section. This operation involves making an incision through the abdomen and uterus in order to remove the baby. Caesareans are usually performed when a vaginal delivery would lead to complications, although some women choose to have their baby delivered this way. Photographed at the Hospital Robert Debre, Paris, France.
