"because bleeding forever is..." *blink blink* "bad." -senior quote
Glompy Sings 6 - Michael Aranda
Bleeding forever... is bad
I learn a lot from this channel
tweed
I laughed at this comment a bit too much.
tweed it's not *that* difficult to understand what's being said, but it's difficult to actually store the information, instead of forgetting about it after the video is over
"Bleeding forever is, uh. Bad."
Killed me.
Justin Reyes so you bled out that's very sad
You can be sure that I don't have an artificial heart; All natural muscle in here
Also no brain - just muscle there.
Brain muscle actually. I have a muscular brain
Muscle Hank's heart is gonna pump you up while it pumps you blood.
..... what did you do to skinny Hank..
u and angry old hank green are everywhere
I've had two open heart surgeries in my lifetime (and one transcatheter valve replacement just two years ago), and will potentially have another 1-2 as I grow older. I'm fascinated by the machines and advances in tech that have happened between my surgeries. Monitors that were the size of a small child during my first surgery, and now the size of a pager. It's incredible. Thanks for sharing this!
Why don't u study software engineering and ai so u can try to help ur self
How do your ribs feel after the surgeries? They must feel horrible, right? Seems incredibly painful.
@@lazybean4365 yea its that easy
Thanks for putting this out today... My step-dad just learned today that he will need open heart surgery and I happened to see this in my subscription feed. Weird coincidence. Amazing how far technology has brought us.
How is he now?
He commented that 2 years ago
@@placeholder6373 He had the surgery with no issues and he has been doing great!
@@iKleb wow ok thats good
@@vaughngrant9678 and i wanna know how he’s doing 2 years later whats wrong about that
I'm actually currently applying to do a Master's in cardiovascular perfusion. I want to be a perfusionist, a person who runs the heart lung machine in the operating room. It's a little known profesion. I would highly recommend looking into it if you are interested in healthcare, surgery, physics, chemistry, and biology.
So what is the problem today with the heart lung machines that they can't keep people alive longer? Just curious, not that it's much of a life. What damage is done with these membranes?
Matt Shapiro
It would be totally worth it, just to be able to introduce yourself as a ‚perfusionist‘ at parties 😁
Just kidding...sounds like an exciting job! Studying medicine sounds very intimidating to me 😎
Dejay Rezme to be honest I don't know much about what are the issues with today's heart lung machines. Perfusion is a VERY new field in medicine so there is a lot to learn, and on the whole today's heart lunch machines are pretty good. I know there is a lot of research going into what are the best practices (types of pumps to use, constant vs pulsatile flow etc) which give patient's the best outcomes, but that's true for a lot of medicine not just perfusion. Today's ECMO (extracorporeal membrane oxygenation) can actually keep people alive for weeks (some other comments on this video say a few months.)
Dejay Rezme The bulk of the issues stemming from using the heart lung machine is the systemic inflammation, immune response and coagulopathies resulting from the exposure of the blood to a large foreign surface. Exposing the blood to the large surface area of the tubing and oxygenator consumes platelets and other coagulation factors while activating immune and complement response.
Another major issue of these machines is physical trauma to the blood.

Matt Shapiro Toronto general hospital was able to support a patient on ECMO for about a week after removing both of her heavily infected lungs. ECMO really can do crazy things!
Jacket's missing; I guess they finally got heat in the studio!
Please add more photos into your videos :) seeing the different prototypes of bypass machines would have been cool and would have helped me to understand how they worked
Kate Tye
Totally! More pictures and illustrations please! With the fast pace of these videos it’s sometimes really hard to follow along....
Kate Tye I was thinking the exact same thing
"It's a bypass. You've got to build bypasses."
The disk/drum thing sounded like old computer memory.
I've had two open heart surgeries and will likely have more at some point. Thanks for giving a history on the development of the blood-oxygen-bypass-machine (I'm sure there's a more technical term, that's just how I know it)!
Keep up the great work!
It takes the heart of a scientist to make an artificial heart. Thanks Scishow!
The doctors told my uncle he needed heart-transplant surgery. He was going to do it, but had a change of heart.
I am a venephobic
Gavin
What are you saying? That my attempts at humor are all "in-vein" or that the attention I get is making me vein? ;)
Master Therion Haha dad joke level: MAX.
Pls leave now PLEASE LEAVE
to people in both hemospheres*
I love watching your videos💜
One of the most interesting videos I’ve seen in sciShow. One wouldn’t realize blood is so delicate and the amazing process that was replicated by these scientists
We'll be learning about heart surgery next week. Thanks!
Wow, what a coincidence! MY aunt just had triple-bypass surgery last week! It's really cool to learn more about how the doctors did it.
Nice video!
Thanks for the video! My dad just had bypass surgery earlier today!
I wish that they would talk about the Left Ventricular Assist Device (LVAD.)
Great video as always guys!
One thing though, I wanted to read more on the subject and when I checked your sources in the dooblydoo they seemed to all be about the cornea. I hope your read this and fix it (in case it's not a glitch on my end).
Anyways, keep up the good work!
You guys are the best. thank you for the great healthcare science and stuff.
thanks for this video
Yay Michael!
Glad I watched this after my surgery. Even though it's been half a year since then. Having a heart attack at 21 is surprising enough but the though of a machine not working properly during something very crucial would have me worried... I doubt I'd even be thinking of this video while I had my heart attack lol. Love how medical technology and methods have improved over so many years. Helped me make full recovery in, to me, such a short time.
Gibbon's passion for medicine has saved countless families some truly heart-wrenching moments
I'm open-hearted for that
twice in my life age 5 (1973) and in my 30s still amazed by the process and tech!
my paternal grandfather had a quadruple bypass when he was 44, and my father had one when he was 45. they were in 1980 and 2006, respectively.
to stop my grandfather's heart, the surgeons opened his ribcage and poured a bucket of ice into his open chest cavity.
to stop my father's heart, the surgeons applied two very small electrodes and gave it a zap.
after my grandfather's surgery, they told my grandmother that he had eight years to live, and they were exactly right.
after my father's surgery, they told my mother that he has 20 years to live, and it's been sixteen.
twice what his father had after his surgery.
the development of medical care is astounding, and definitely one of the reasons I've chosen bioengineering as the field I would like to go into
Thanks for nice explain
Being a perfusionist is a great opportunity to stop their heart and takeover their life for few hours and restart it back is like a excellent dance between life and death . I am really proud for what I do as my profession. Thanks for creating awareness around medical technologies which improves quality of life of people around the world.😊😊❤️
I once got thrown in jail for doing Open-Heart Surgery
NEO: " we need Hanks..........lots of Hanks! "
Hustle Hank
I thought you were going to say you stole someone's heart.
@@Master_Therion yeah he tried that but she said he was to "short"
As a perfusion student, I approve this video. Heart surgery is amazingto learn.
We just gonna ignore the several types of "Hanks" in the youtube comments?
What's going on!
They're certainly not being ignored.
ADEX
They’re annoying and not funny
ADEX yup... insanity LOL
Yes we are going to
He looks younger. Another great video.
I had an open heart surgery when I was little, so it was fascinating to see that video and understand it a bit more
I was one of the first children put on a bypass machine in the US. Had a “temporary repair” surgery in 1962 to help me survive long enough for technology to develop to put children on the bypass to do the actual repair (in 1965). I also found this video very enlightening.
@@lindacondray7918 WOW! glad it turned out good
I was a chaplain at Rush University Medical Center while a man was kept on the Extracorporeal Membrane Oxygenation (ECMO) heart/lung bypass machine for over nine months. There is some pretty amazing technology that can be used when the heart and lungs need time to heal - even outside of surgery.
Thanks for awesome content. Just wanted to tell you that there is a barely noticeable hiss or noise when Michael speaks. The noise gate probably switching on and of constantly. Maybe you can fix it with a constant background noise bed. I can notice it only here and in the fish episode. Hope it helps
Thank you
0:20 nice v12 you got there running your body for yah.
All I know is I'm liking Michael's hair so much that my heart might stop
My dad recently had a heart attack, but they couldn't perform open heart surgery because one of his arteries (or whatever you call em) was over his heart, which was rare. So instead, they put in some stints. Worked out alright in the end.
Wow! Makes me feel good I said no when a cardiologist wanted me to get a triple bypass! He was angry that I challenged his authority but did put the stents in instead, just as I asked him to. And now, three years later, my heart is doing great (and I have a different cardiologist).
It's poetic, though not too surprising, that the best artificial solution to gas exchange for blood so far is basically alveoli.
I'm just incredibly grateful I was born in 1977 - and only had to wait 4.5yrs to have my open heart surgery! Prior to the tech evolving enough, I wouldn't have seen 10yrs let alone my current 40! I F*cking Love Science!
If I'm not mistaken, the original open heart surgery, the BTT shunt (more commonly known as the BT shunt) was developed in the 40's and was completed without a bypass machine. The surgery had to be performed very quickly to prevent their patients from dying because of this. So technically, you CAN do open heart surgery without a heart lung machine, but the risk is no longer worth it now that they exist.
I love sci show
I wish they would do a pharmacology series it would help with classes
Hey! It's winter but Mr aranda doesn't wear his vest! What's up with that? Haha love the videos 💋🍄💋🍄
You should do a video about trichotillomania. Would really inform the people who have it. Like me
what would be cool is if you could have a tiny pump installed in one of your main arteries that would automatically start up when your blood pressure or flow rate gets too low, possibly giving you enough time during a heart attack or a bad arrythmia to get medical help so you dont die
even 10 min of backup time could save millions of lives, particularly the elderly and those with heart conditions
Having personally seen multiple bypass procedures, these machines are definitely taken for granted. We simply expect them to work during the procedure, and they do. On the topic of heart pumps, LVADs are newer internal heart pumps for patients awaiting heart transplantation. Most are centrifugal and the patient does not have a palpable pulse due to the constant flow of blood. One has to use a doppler to check blood pressure. Eventually, open heart surgery will rarely be used. Cutting edge technology now uses percutaneous procedures to replace valves and repair structural defects within the heart. All through the femoral or radial artery in a cardiac cath lab. The future is great.
fun fact first open heart surgery done by a black man.
Asley IceGold That's right
That’s crazy, and dope! Nice.
I had open heart surgery when I was 31. Course I didn’t experience anything, being on anaesthetics, until it was done. And then I felt pain. Lots of pain.
So I was on ECMO for a week... it's pretty cool. Set the world record by holding my breath for 24 minutes.
i got the creeps at the "ripping the rip cage open" that sounds horrorble!
My heart can't take this damage..ooOOOOoo
That's a lot of damage
And What happen if they use the right or the left lung like a blood
pump. After some artifical modification it can transport blood instead
of the heart, without external powersourch.
Interesting. But I'm glad I didn't know this before my open-heart surgeries. I would be worried about all of the things that could have gone wrong. Sometimes, ignorance is bliss!
ansapo so much for informed consent.
I had heart surgery for valve replacement fix when I was 7
I wonder if we brought magnet near to our body why don't they attract rbc's (as they ad made of haemoglobin made of heme made of iron)and if they do why blood do not clot
Why can't pumps be used to route the blood from the body into the lungs and then pump it back into the remaining body? i.e. Why do lungs become inoperable during open heart surgery?
I wonder if there is a way to use a donor heart and lungs inside a machine to do the job during the bypass operation.
Can they do blood transplants on arthropods?
Very nice video but not sure what that line at the end was about "even the most advanced artificial hearts can't keep patients alive for more than a few days MAX". A CPB machine can't be used for long, but there are several techniques that can be used for weeks, months or years. ECMO is like bypass but can continue for weeks, VADs and total artificial hearts can keep people alive for years. So that is completely wrong. But otherwise accurate.
There are actual artificial hearts, that are not heart/lung bypass machines. The first one used was the Jarvik 7 in the 1980's.
These are used to prolong patients life while waiting for a heart transplant, or in a few cases, to keep someone alive for years when a transplant isn't possible.
They did that to the younger of my twin sons when he was 3 months old, it was a harrowing experience but he came out of it restored to normal health, the doctors patched up n VSD and ASD, so he's got some goretex in his heart for the rest of his life.
You should do an episode on actual artificial hearts. Machines meant to be working replacements of the heart that are battery powered.
The challenge with a bypass machine is oxygenating the blood, not pumping it. What you were discussing was an artificial lung.
show the gifs of blood circulation with drums, disk etc.
There are a LOT of accidental groundbreaking discoveries in science!
Is there any research being done on artificial stomachs? Because that's the one I'd need ;w;
Could you do an episode about iron lungs and how they work?
Still tweaking it?!? I thought those things were done already! Would have loved to know that before my o.h.s. a couple years back!
Why after chewing some minty gum or eating mint candy water feels a lot colder?
Xnenomorph,... I was thinking artificial gills this entire video LOL
What exactly triggers blood coagulation? If it is by contact to something in the air, wouldn't it happen all the time in the lungs?
I really really hope that artificial hearts will work without problems soon and that batteries becomes better. I had a major heart attack 2 years ago. I really really hope for this technology.
Interesting but there is an unanswered question. How do they connect that machine?
What is more intriguing is the Artificial Fart.
I have finally reached the point where I can see the 30 fps in videos, I realized it while watching this video. I'm not annoyed by it but it is a little distracting. I'll probably just have to deal with it.
They should attach artifical hearta in as many locations as possible
The foot the legs everywhere
The reason a person has blood clots it the heart doesn't have the strength to push the blood from the chest to the foot back up the leg back to the heart
That's if you want people to live after this surgery
If you don't want people to live then just put one artifical heart in the chest and they're survival chances will be very low
Bleeding forever is just... Uh.. bad!
Can a dead be reviewed by artificial heart?
Maybe Carbon Nano-tubes could be used as a membrane...Just a thought.
Thats it, being called a gibbon is now officially a compliment.
Just realized that this is the guy that charlieissocoollike would collaborate with on videos back in 2011.
Why does Micheal blink almost never blink?
The key to artificial heart is artificial love.

ECMO would like to have a word with you.
My heart was on bypass machine for seven hours, in my childhood...
Heparin can be dangerous if they goof and use tomuch..BTW i have had 16 Operations
I'm surprised Michael didn't show any clips from "Experiments in the revival of Organisms" - perfect for the tubeyubes.
If you didn't know, this was a 1940 soviet documentary (since reproduced in English) about the Soviet development of the Autojektor by Sergei Brukhonenko et al. Their experiments and the development of the Autojektor was completely separate from Gibbon's research, and culminated in the first Soviet open heart surgery on a human in 1957, only 4 years after the Americans.
What's really cool is that there is a ton of amazing footage of their research.

Artificial hearts can and do keep people alive for more than a "few days max".
