No pulse...ROBOT HEART
I'm a biomedical engineer, and I'm here to tell you all that there is not a device to replace your entire heart... Yet.
@NotCaveJohnson, is one of the main reasons why they havent made such a device is that when you work out the device wouldn't be able to supply enough oxygen to your muscle tissue because it wouldn't respond to the nervous system telling it to speed up the rate of blood flow as a normal heart would?
@NotCaveJohnson, you mean something on the internet isn't true? Shocking!
@NotCaveJohnson, thanks Cave
@NotCaveJohnson, sure they do! It's called a pig heart
@NotCaveJohnson, Didn't the Autojektor or something like that created by Soviets work as a heart for a short time?
@NotCaveJohnson, as a student pursuing a bio engineering degree, I must ask you, is it worth it?
@NotCaveJohnson, just saying, if that device would replace your heart but you wouldn't have a pulse... Wouldn't that mean it's not doing its job? Or at the least mean your blood will coagulate? Could be wrong just wondering
@NotCaveJohnson, You're obv. either not a biochemical engineer or maybe just not a good one. We have a patient with a total artificial heart in our cvicu at this very moment. Look it up. Thanks. And the pulse isn't the problem, so long as there is constant flow.
@Wendigo, they are trying to say the blood will be pumped continuously, not in beats. Probably not true
@NotCaveJohnson, with the exception of other biological hearts
@HookEmHorns, so I looked it up, there's the syncardia total artificial heart. The purpose of the device is to to extend patient's life while on the donor list for heart transplant for proper tissue matching. It was just approved by the FDA. Always temporary, you have to carry a huge pack with you to pump the blood through an external device, and you still have a pulse. I wasn't aware of syncardia, if that's the device you're talking about.
@poopnuggets, I like it, I didn't go with an undergraduate degree in it though, I got it in mech eng. I got a grad degree in BMEn. You can stick around in academia doing research, or you can work for companies making medical devices, or start your own company, you'll make a very comfortable living and help a lot of people. It's up to you if it's worth it.
@HeroOfFunnypics, one of the largest hurdles in a heart related device is regulatory. The FDA is a stickler for safety and efficacy of medical devices and the process takes 6+ years to get approval before going on the market with a high risk device. The syncardia Cardiowest is a total heart replacement. You can read papers about how it operates. But the reason it exists is not to replace the heart permanently, it's to keep patients on the transplant list alive until a donor is found. The device has been made but all the mechanics of the device are outside of the body, but shrinking it down to be self sustaining and fit inside someone's chest for more than a year of two is a much more difficult process. Every iteration to get to that point will need to go through the same approval process.
@HSA, I feel that this could somehow go terribly wrong.
@NotCaveJohnson, but there is a man who has a turbine for a heart, and has no pulse.
@NotCaveJohnson, I found a rare treasure, a comment series that interested me. Thank you for being an engineer
@HookEmHorns, I was going to say--- pulse has to happen as pulse is the force of the blood being pushed through, correct? An artificial heart replaces the old heart which means it replaces the features such as pumping blood. Thanks for your input- I was sure artificial hearts already existed
@SchroedingerPussPuss, not exactly, a pulse is from the way your natural heart works, with the left ventricle contracting and sending blood through the high pressured arterial system, a TAH provides more of a constant flow. Pulse isn't important so long as you have blood pressure and movement to continue to bring o2 to the cells and remove metabolic waste through the lungs like normal cardiovascular function
@NotCaveJohnson, I mean, yes, it's temporary. However, were extended use to cause patient death, that would still qualify as working "for the rest of their life."
So wait ... you are telling me I can be iron man?
Wonder how much horsepower you have with it
@Who ate my pig, all of them
This artificial heart comes from the movie "Crank 2." It also comes with a portable waist battery pack and I would not recommend recharging it the way Chev Chelios had to do throughout the movie.
Wouldn't that kill you or am I missing something?
@Polaroid, No, you don't necessarily need a pulse. The pulse is the heart contracting and expanding to push and pull blood through the body. If this machine could keep the right pressure and keep the blood constantly circulating, you wouldn't have a pulse.
@Cat Lauer , wow, the more you know...
You would still have a pulse...
@AliG, not if the blood flows constantly. as in a water pipe
@Chick33n, this is true. It just pressurizes the blood without making the "Lub dub" that we call a pulse
I see the up side but this still leaves me uneasy..😅
How is that a bad thing?
Don't see a down side
@imperialwookiee, have you not seen crank?
@Theodore Roosevelt, nope
@imperialwookiee, man gets implanted with this heart. Man has to use hard drugs and other uppers or he dies.
@imperialwookiee, might be thinking of crank 2 with Jason statham
@Theodore Roosevelt, oh yea I remember it, so basically drink monster all the time?
@imperialwookiee, walk around getting tazed all the time
@Theodore Roosevelt, been tazered don't want that again
Looks like a mini engine for your body
Freak the fvck out of all hospital workers when you come back from the dead
I'm a doctor and have worked with those devices. The image that we see in a Total artificial heart. It is still on the research level and is accecible only in a few research centers. The Ventricular assist device is what is actually used as a 'mechanical heart' to this day. It's used mostly for a bridge to a heart transplant. The majority if its components is outside the body and the patient's heart remain. It is true that some models only provide a steady flow wich means no pulse. An other interesting fact is that with no pulse you can't use usual ways of taking blood pressure (the 2 numbers usually taken are from the relaxing and contracting phases of the heart) .... Oh and yes... It's damn freaky to have a patient smiling and talking to you with no pulse and some weirdly low numbers of BP!
One step closer to the cyborg future ice always dreamed of.
I can live with that if it were real
Dang. Mercedes taking it to a whole new level.
That looks like something I would smoke out of.
you could trick people into thinking you're Dead with this :D
