A fetal ultrasound report suggesting venous catheter a-wave reversal is an indication that the baby is suffering from severe oxygen deprivation and is on the verge of death. It is recommended to see an obstetrician as soon as possible. If the gestational week is 28 weeks and above, terminate the pregnancy as soon as possible to save the baby. If the pregnancy is below 28 weeks, administer oxygen and lie on the left side to improve the hypoxic environment. Review the fetal ultrasound in 1 hour to see if the baby can be saved. Take care of your rest and keep the air circulating in your home. Have regular prenatal checkups and pay attention to reasonable diet.
