pulse oximeter - altering heart rate while holding breath

[xEmoLov3rx]

I AM THE QUEEN of pulse oximetry machines. I have asthma! But, i am usually hooked up to a nellcor or a masimo with a phillips heart monitor.

[mercurio0000]

Cool! I did not know that.

[pilotbaxter007]

Try the Masimo rainbow SET

[pilotbaxter007]

In your info, when u said u had sinus tach, fi, that's a tracing of the spo2 plotted as a function of time  [ f (time) = SpO2 ] , not your EKG.

[bionerd23]

how do you call a pulse over 100 on a pulse oximeter, then?

[CexsnVida]

@bionerd23 What he means is that the image that represents your pulse in that machine is not an EKG. An EKG is based of off electrical pulses, while an oximeter is based off of the SpO2 (as your heart pulses, your SpO2 changes). A pulse over 100 will be greater than 100, but your oxygen saturation percentage obviously will be always less than or equal to 100.

[bionerd23]

@CexsnVida

well, the pulse oximeter still displays the peripheral pulse (bottom), and as long as the heart is in sinus rhythm, that pulse will be equal to the heart frequency.

[alin0steglinski0]

0:54 is awesome alarm

[bionerd23]

lol yeah, i should've stolen the machine! :P

its looovely. i like the R tone as well.

[alin0steglinski0]

very stealable looking :P

i cant do breath holding... or anything cutting off my air, i desaturate like a motherfucker

[medicaldud]

Yes. Very stealable looking.

[the3freeman]

50-60 on day, it's very good man !

guess you do a lot of sport ;)

[medicaldud]

This video is AWSOME.

That pulse oximeter u were using is a Masimo.

Cd u do more videos of you on ur ECG machine?

[bionerd23]

thanks - what exactly would you like to see?

[gyan786]

Why did you block 1992peter

He is VERY interest in this stuff. He has to use a lot of it, because he has health issues, so that is why he is so curious. To learn about 1992peter check out his profile.

he is NOT some kind of creep who gets off on people using those machines.

[sciencoking]

im schlaf kann der puls auch kurz unter 40 fallen und man hält unwissentlich bis zu 3 min die luft an... was dann erst die Herzen und lungen der extremsportler machen...

[sciencoking]

man wie viel beruhigungsmittel hat der denn genommen? der puls geht unter 50 is jan wahnsinn das glaubt nich mal das gerät lol

[bionerd23]

naja, extremsportler haben mitunter n ruhepuls von 40 - aber der ist garantiert kein extremsportler. o_O

so viel besser ist meine sinustachykardie aber auch nicht... :-P

[kmill31415]

I once had the chance to play with one of these. I didn't think to hold by breath, but it was fun to try to slightly alter my heart rate just by concentration. My friend couldn't get it to pick up her pulse, so I joked for the rest of the day that she was actually dead.

[thegrizzly1]

what i dont get is the thing above ur pulse was the resprtory rate and it was moving? if ur not breathing ur respirtory rate wouldve been ------------------------------­-----------

if that was ur respirtory rate? or maybe that was ur BP?

[bionerd23]

it is the oxygen saturation of my blood in percent...

[thegrizzly1]

no wonder why its eratic :P

[grenouil1970]

Super !

:O)

[LizzyAston]

when i went to the hospital i could make it go from 80 to 115 BY USING THE POWER OF MY MIND!

not holding my breath

[sciencoking]

whoa can you teach me?

[LizzyAston]

i have classes every tuesday, 6:30 pm at my house, with the aim of learning how to change your heart beat by thinking about it. i'll see you there.

[sciencoking]

sorry but that´s nearly impossible

cause I live in Germany

[medicaldud]

Do you use a pulse oximeter for a class?

[LizzyAston]

yes, but the newer generation models work better so we have decided to invest in those.

[meggiemeg86]

What does it mean if you heart rate goes up when you hold your breath?

[bionerd23]

i guess its physiological - the heart tries to make up for the lack of oxygen with a higher heart rate. i have no idea why it would go slower, though... *shrugs*

[XxkutaapxX]

couse if youre hearth would pump harder when you're holding your breath i think it'll cause all the CO2 in your longs to get back in your blood....maybe...

[sciencoking]

eer no it´s an energy-saving-mechanism to save oxygen if you e.g dive

everyting that is not directly imprtant to survive is immediately "turned off"

and so your heart can relax and beat slower

if your body would simply go on with its work you would soon have no more in your lungs...

[sciencoking]

yes forgotten the word oxygen due to tiredness

[bionerd23]

i guess its physiological - the heart tries to make up for the lack of oxygen with a higher heart rate. i have no idea why it would go slower, though... *shrugs*

[macat73]

it can be a sign of heart disease, such as a heart block or or sometimes when one is taking more than the prescribed dose of a beta blocker or sometimes it can be caused by some thyroid abnormalities. . .

[1992peter]

I need some help.

There were two alarms.

One the beeping noise stopped and the alarm started and the next one, the alarm went off again.

Could you explain that to me?

THANK YOU

[bionerd23]

one alarm was because the sensor was disconnected ("no pulse"), the other was because my friend's pulse rate dropped below 50.

[1992peter]

You're COOL!

Do you ever sleep with it on? You see, I'm interested in medicine and I love watching videos on heart monitors, pulse oximeters, ventilators, defibrillators, oxygen delivery systems, etc etc.

I've been interested in medicine ever sence I was about THREE and have been studying, collecting, writing, and even PLAYING with medical equipment.

I write about what it would be like to have a pulse oximeter in my ROOM where I SLEEP.

[bionerd23]

no, i never sleep with it if i dont have to - the electrodes are pretty annoying and get itchy over time. i often have long-term ECGs and stuff (because i have heart arrythmia), and they annoy me a lot. :-P

but yeah, i also agree that medicine is pretty fascinating. see my other videos, i even saw my heart beat LIVE (xray) when they did an intracardiac catheter on me. my heart MRI is also pretty nifty. :-)

[LizzyAston]

REALLY? Is that SO? That's AMAZING!

lol :P

[alin0steglinski0]

wow peter, i am just like you, i am obsessed with medical equipment, i would love to have one of these where i sleep too, and a full patient monitoring set up just for the heck of it!!!

i also love blood pressure cuffs, since i am autistic i tend to be relaxed by pressure squeezing me, so id like to have my own manual blood pressure cuff one day... gotta be careful, i know ill want to wrap it around my head or neck one day lol..

[1992peter]

All right

Holy Cow

You have an ICU monitor in your house?

Where on earth did you get that?

Now wouldn't that COST about $5:00 or something like that?

/And thank you!

[bionerd23]

yeah, its a Hellige SMU 611 monitor which can be upgraded with different modules, such as pulseoximeter and (invasive) blood pressure, temperature, etc. i found it on ebay and it cost 100 EUR (about $150 USD).

[1992peter]

Nice one. Could you do another pulse oximeter demo?

[bionerd23]

no, as that isnt my pulse oximeter - it was a temporary exhibition in newcastle upon tyne, england. sorry!

[nguclear]

Thanks a lot! I was doing research on the effect of breath-holds on heart rate when I came across this video. I was worried because suddenly I saw the heart-rate increase in the middle of it. Just wanted some confirmation or else my entire lab is ruined. Thanks again! Keep up with your videos lol

[nguclear]

My main confusion was the orientation of the video. I was unsure exactly when the human subject started to suppress breathing.

[bionerd23]

there were two people doing that, actually... first me (goes from sinustachycardia to a rather normal heart rate during breath hold) and then my mate (goes from normal heart rate to almost sinusbradycardia during breath hold).

[nguclear]

I was wondering, since I was a little confused, whether this video verifies that heart rate decreases with longer breath holds. If so, why did you mention that you had an abnormal heart rate (sinustachycardia)? Or were you referring to your resting heart rate?

[bionerd23]

yeah, exactly. i was refering to my resting heart rate.

[TimGBone]

That's pretty cool. My resting heart rate is pretty slow actually, around 57 bpm.

[promattos]

I could reach 38bpm by morning holding my breath... after 1:30 minutes hr raise to 80bpm, and maximum 90. Lay down...

[bionerd23]

wow, thats pretty low! actually, thats bradycardia. :-P

i can never go that low, i have about 70 bpm even when im utterly relaxed. usually, i am around 100, as you can see in the video. i'd need a beta blocker to go lower. ;-)

anyway, i'm known to have heart arrythmia, as you can see in my other (ECG) videos. so yeah, a pulse as fast as mine sure is pathological.
