Fetal Circulation and Baby's First Breath

[styxtap]

I wonder if it makes a difference in where your first breath comes from? The state of the air in the location of your birth... dirty? clean? lush with plants? cold? wet? dry?

[cherry6254]

I found it very witty the way you mentioned holding your breath for nine months. Are you a cardiopulmonary doctor?

[PrettieDebbie]

i'm a medstudent d@ has an exam in 2days n instead of payin attention 2 fetal circulation, is admiring a hot guy wt sexy eyes n a breathtaking voice!

[BradFazner]

holy crap you are one big dork!

[wlaa2009]

great one!



[doorslammerules]

Great video dude! this is cleared all my doubts! its gonna help me a lot tomorrow for my embriology presentation

[auntiecindylovesmina]

Great job! Thanks:)

[PatientScientist]

Thanks for this. I'm in nursing school in NJ and this really helped clear up some questions about fetal circulation.

[Liszz90]

Great Video!! Thanks! I'm studying medicine in Germany.

[memtu1]

Amazingly u ave managed to give an african student a clearer picture of Fetal circulation. BTW u humoured me thru out the learning process. thnx a lot #memtu#

[teedubya90]

o2 is a vasodialator in the lungs but a vasoconstrictor in all other parts of the body right?

[mmh3999]

@teedubya90 Yes you are correct! That is why, in the case of Pulm-embolism we have Pulm-Shunt!

[th3mojoh]

@teedubya90 exactly



[thoserubyslippers]

This helps thanks:p

[nvk1001]

I will pay for your flight to the uk if u sit my med skl exam 4 me. Im totally serious btw!!!!!!!!!!

[vlforman]

[PazPanda]

Reminds me of the Winklevosses!

[coolgirlee]

Omg your voice, I want you. Come tutor me.

[christyk3377]

He's such a sexy guy! Intelligence and sex appeal... great combination.

In all seriousness, it helped a lot. I have to be able to visualize something as complex as this and you helped me accomplish this understanding. thanks a lot!

[jsmoothcp]

I love this guy!

[tristanyip]

you are smart ass

[levrone007]

elegantly put well done!!

[sparklexo1]

can someone sum up the video for me? i have add and cannot focus

[hemed86]

that was verey helpfull for me thank you!

[theNainanancy]

I had to go through this twice,only cos this guy distracted me!

[rhojanjanie]

@theNainanancy

hahaha! true!

[adityahs2]

yo man..ur goin to rock my exam tomoro..thanks anywayz..!

[yourcelebrity]

Will you marry me? I am swooned by your intelligence and good humor. Your face isnt bad either :) LOL!

Brilliant video! Nursing instructors are using it as one of the supplemental resources for fetal circulation concepts. Thanks! <3

[Be1smaht]

I cant watch this anymore...because I am attracted to this guy . But seriously, your very good. Did u go straight from undergrad to medical school? or did u take another route? just graduated trying to find out more about pgrams to get into medical school.

[odiug95]

I once heard that our first breath is the most painful and traumatic thing we suffer in our whole life.

[crnokes]

wonderful ...thanks for the explaination

[111numnum111]

thank u very much ...... very helpful informations ...

[dollarbill11]

does that mean that fetus uses the coronary arteries for poor dehydrogenated blood and the veins for rich oxygenated blood?

[65stein]

Thank you! Helped me out a bunch : )

[earthymoon]

Thanks. This helped tie up some loose ends on my understanding of fetal circulation.

[jessyka026]

Thank You!! Very Helpful!

[medstudent1234]

Thank you! Great video!

[annaluvs7]

Awesome

Thank you so much

[Rigelcentauri58]

This is a very instructive and practical video. Congratulatios!!

If you allow me to make an observation:

At 1:31 you sate ¨blood from the mother enters through....¨ . It should be: The fetus´oxigenated blood enters through...

because we don´t have mother´s blood

inside the baby, as they must never mix.

Thank you and felicitations, you have a great capacity transmit knowledge.

[sukyca]

very simple and very helpful. thanks

[spd2841]

so helpful friend. Thanks

[emmsno1fan]

awesome video!! helps so much

[mbello356]

i .... love you so much! perfect :D

u r a genius <3

[Bacoobs]

Thanks a lot for this video. I start clinical tomorrow on a pediatric cardiology unit and this helped me immensely!

[mjfollo]

Thanks so much for this video. This has helped me immensely to understand the fetal circulation system.

[tore8787]

isnt there a mixture of both oxegenated and unoxegenated in the right atrium? the inferior vena cava doesnt just continue through the atrium to the foramen ovale. these are important details dude.

[jmtrevino7]

This is great! I love the way you break it down --- I'm sure this is going to show up on my cardio test!

[90jatti]

helpful..thanks

[johnandraquell]

Thanks buddy, good providence in med school

[missrosine]

haha ... loved it! super interactive & helpful. much gracias.

[DJRHutchon]

Very nice video and like your mysterious introduction. As others have commented pity you simplified by saying blood coming form the mother rather than saying it comes form the placenta which you mentioned at the begining. Your diagram should have shown the ductus arteriosus much larger, it is almost the same diameter as the aorta. However the main thing in your diagram was the cord clamp! If it had been on your cord before you had been able to start to breathing you would not have been so smart

[oogeekgirl09]

This video really helped me understand fetal circulation. Now I feel more prepared to take my final tomorrow morning! Thank you so much!!!

[kingdavidification]

thanks, it helped

[songstres4christ]

thank you very much! there's not many good videos available about fetal circulation. I needed this......... thanks!

[mantArulz]

Thanks a lot, it was a great help, :)

[Be1smaht]

Hey I'm studying for My MCAT. Still have a few questions about this ... I'll contact

[TheExPlOiTeDOne619]

Thanks a lot bro. You should become a teacher :D

[comcv99]

that was great help!!

[getindianmusiconline]

pretty informative lol! I found holding the breath part in the begining pretty funny that got me thinking.

[00HaMMoDaH00]

there's an important point .. the oxygenated blood that goes to the inferior vena cava representing about 50 % of whole oxygenated blood that enters the fetal circulation through placenta .. so, the other percentage 50 % goes to the liver & then, portal vein to supply the right side of the liver ..

great creatures, aren't we? .. : )

thanx Dr for this presentaion, it's really helpful ..

[karamellmann5]

Thank you very much! Nice to see that there arent only pointless video blogs and monkeys smelling their genitalia on youtube (even if its actually funny :p).

[helenkellerx06x]

Yeah as commented before Mother's blood does NOT go into the fetus' circulation. Mother's blood goes into the placenta where an exchange occurs of nutrients and oxygen occurs, but the mother's blood goes back to her heart. The baby can have different blood type from the mother so if her blood went into fetus, agglutination can occur from clashing antigens with antibodies

[teamriras]

Apologies for any confusion in that comment, it is a simplification clearly, and refers to the directionality of the blood (which is always that of the fetus) and not the actual source of the RBCs. Blood going "to or from" the mother was intended to illustrate the direction of fetal blood flow, so I apologize if that seemed confusing; "to or from" the placenta would be perhaps more clear.

[clsamp0]

Not bad but oxygen isn't a vasoconstrictor as you stated in the video. It is the decreased CO2 content that causes vasoconstriction in a vessel....well all vessels except for the lungs which actually constrict when CO2 levels are increased. Just thought you might want to know!!

[simonohare]

massive problem with the comment that the mother's blood enters the baby, otherwise quite useful.

[tnjmoore]

I am teaching some nursing students, may I use your video for demonstration?

[woodze21]

the mothers blood never goes into the baby! it goes into the placenta where nutrients and oxygen are exchanged and then it goes to the heart and other important organs

[rizziriccardo]

Thanks sooo much!!!

[scandichika]

Thanks, that was great!

[jessicaquesada21]

Freaking awesome simple explaination, and "instructor" is easy on the eyes. :)

[lifeguard1111]

You said that the lungs are not inflated.. Actually the lungs open. They may not have air in them but there is fluid in the lungs to maintain the fetus Function Residual Capacity. Thus preventing Atelectasis or Lung collapse

[melaniemarhefka]

you make fetal circulation sexy

[AvenYinYang]

@melaniemarhefka dude that sounds so creepy!!!!  :D

[blackacacia94]

wow...nicely made! =O you just saved me on my biology exam lol. =$ thanks for sharing!

[AndrewKFletcher]

Immediately after the first breath, there is also a density change that takes place in the fluids at the surface of the lungs and respiratory tract as evaporation takes place for the very first time. This will undoubtedly release a pulse of solutes into the heart that will flow down the main artery enhancing bloodflow providing the baby is in the inclined position rather than horizontal position. A head up inclined posture may be prudent in assiting this initial flow of blood.

[amrutvani]

A small query.how blood from pulmonary artery goes to aorta (thru ductus) where pressure is very high?In fact blood from aorta should go back thru ductus to pulmonary artery.

[teamriras]

actually, because the resistance of the pulmonary arteries is so high, when the right ventricle contracts it sends almost all of the blood directly through the pulmonary trunk and into the aorta, essentially bypassing the pulmonary arteries.

[amrutvani]

Agreed but does that mean right ventricle undergoes hypertropy and is thicker than left ventricle in fetus ?

[seclarkern]

Thanks- you just saved me hours on my power point for new neonatal nurses in NICU orientation!

[Malikacf]

I'm in my sophmore year of high school and I have a worksheet to do on this topic. I don't have my notes but fortunately this guy made an informational video!!! Thanx

-Malik B.

[monkeyintrouble]

wow - that was really helpful, i'm in first year med and we are doing this right now, and i couldn't understand it for the life of me....until now! thanks:)

[aleena24]

This was very informational. Thank you for this video.
