Hi, Sherlyn. I'm a medical doctor from Brazil. I would like to say to you that this was the best explanation about fetal circulation I've ever seen. Just amazing. Congrats!
Thank you so much! I was searching for over an hour on medical sites, trying to understand this whole concept, and your video was the best and clearest teaching of them all--in 10 minutes!
Thank you so much for sharing this. I am a new L&D nurse and have been looking for a clear explanation of why we put a pulse ox on babies right arm. This has been so helpful and now I have a true grasp as to why we do this. Now I know why, and am not doing it just because "this is how we always do it."
Thank you for sharing this video, I'm a neonatal nurse just starting my qualified in speciality course and this was a very clear and easy to understand explanation.
Hi Sherlyn, I am a pediatric resident and I have to Tell you that you have made an amazing video for someone trying to understand pre ductal and post ductal readings. I would like to make a small correction, the brachiocephalic artery is distal to the DA and not proximal. I am sure it was a slip of tongue, great job!
Hi @ctguboy, I'm glad the video was of some use to you! And very happy to be corrected about my misunderstandings of foetal anatomy. Thank you so much :)
Thanks this was very helpful. And your voice is really soothing 😂 the video was concise and to the point. You drawing on the photo helped in clarification of the concept!
Thank you so much for making this video! I always need to understand the "why" and rationale behind the things we do or I will never remember to use the correct hand.
Hi Jennifer, great question! I'm not a neonatologist, so it is best to check these kinds of questions with your clinical supervisor. However, to the best of my understanding, it is not advisable to use a foot probe in the setting of a newborn resuscitation. This is because both of baby's feet will be perfused by the left and right femoral arteries, which are situated distally to the ductus arteriosus. This means that for a newborn baby that is just a few minutes old, an SpO2 reading taken off the foot will be markedly lower than their cerebral oxygen saturation. Thus if we were to titrate oxygen therapy to a foot probe reading, we could run the risk of oxygen toxicity for the baby. There are however some instances you would use a foot probe. One reason is for oximetry screening of congenital heart defects, which is usually performed between 4-48 hours after birth. In this scenario, a pulse oximetry reading would be taken off the right hand (pre-ductal) and either foot (post-ductal). In most healthy babies, the foetal shunts close within 12-48 hours of life. Thus if the baby has a structurally normal heart, the pre-ductal and post-ductal reading should be the same after 48 hours. However if there is a disparity of >5%, this could be a sign of right-to-left shunting, such as which occurs in Tetralogy of Fallot. By that token, a foot probe can also be used for routine SpO2 monitoring in neonates who are at least a couple of days old. Remember that the foetal shunts usually close within 48 hours of birth. Thus, it theoretically shouldn't matter which limb you choose to take an SpO2 reading from as they should all be the same in this instance. If you are asked to take a foot probe reading as a birth assistant, I dare say it shouldn't matter which foot you choose. I hope this helps :) please check this over with your clinical supervisor before integrating it into your practice.

I ‘m a paramedic from Taiwan ,clear explanation about fetal circulation,thanks.
Im a newly qualified midwife and needed a refresher on this.. PERFECT explanation thank you 😊
Student MW in the US and I have been searching for this answer for days!! Thank you so much. So straightforward
I’m an old school paramedic with 40 yrs in the career and that was a really good explanation
Thank you Mr Picknell! It is an honour to have your seal of approval :)
I am a midwife in the UK and your video was really helpful! Thank you!

Hi! I am a birth assistant student. If you have a foot probe which foot should be used?
