Opis

an adequate oxygen supply is vital for the undisturbed development of the fetus and its functions. This book gives a synopsis of the ruling influence that oxygen has in multiple regulation sytems in the mother and especially in the fetus. The authors consider oxygen as a manipulated variable or as a corrective element during normal pregnancy, during delivery and during acute and chronic oxygen deficiency. Furthermore, they deal with the consequences that oxygen deficiency has on the fetus.
