This is an ultrasound examination that is usually carried out vaginally at 6-10 weeks of pregnancy. The aims of this scan are to determine the number of embryos present and whether the pregnancy is progressing normally inside the uterus.
When can ultrasound detect fetal viability?
A Fetal Viability Scan is an ultrasound examination, usually carried out at 7 to 12 weeks, to confirm that the pregnancy is developing normally and to provide reassurance. Additionally, this scan will confirm or exclude whether twins are present.
When do you know if a pregnancy is viable?
After 6 weeks, a normal fetal heart indicates a viable pregnancy. A fetal heart with no heartbeat at any point is called fetal demise. After 22-24 weeks, a viable pregnancy is when a baby has a chance to survive outside of the womb.
What can I expect at my 24 week scan?
During this appointment, your midwife will check the fetal heartbeat and will also check for signs of pre-eclampsia – characterised by high blood pressure, swelling, and protein in urine. Your midwife will explain these risk factors to you and you should seek medical advice if you have any concerns about pre-eclampsia.
