Thank you for this! I'm a paramedic student and I was having so much trouble understanding this. But, you helped a lot and now I finally get it. Thank you again.
You are literally saving my arse right now with your visually appealing and humorous videos. THANKS FOR POSTING THESE. Helping me understand my course context!
Hey Will. I am an RT in Canada that recently presented a poster presentation on this topic. You gave a very good basic explanation of this phenomenon. The one peice of information I would add is since we accept V/Q is the problem, and the patient needs oxygen all healthcare professionals with patients like this should consider ways to improve ventilation to improve CO2 removal feom the blood. Good explanation.
olsen jarvis why don't you break Copd diseases apart, advancements or cures...you get a Nobel prize...the cure named after you...and then...your a very wealthy beloved hero...just a idea!!
good explanation! I always need to be reminded of the V/Q ratio. thanks, man! btw, my prof did warned me about this saying that for COPD patient, do give them oxygen but instead of the high flow O2, they should be given controlled O2 to not oversupplying them. since, well from the explanation in this video, that could eventually cause respiratory failure.
Very nearly died in A&E last Friday because I have very minimal emphysema, asthma and rheumatoid arthritis associated interstitial lung disease so I’m a complex case but they always completely ignore the ILD which means I can barely get a breath in, because of the big “copd” issue and if I retain which I don’t, so there I am dropping spo2 rapidly and collapsing on myself while my mum ran round begging them to give me oxygen. This happens every time I’m admitted and every time I do need oxygen. Feel like one day I’ll be gone because of this very issue x
how can i get rid of exersice incuded asthma verytime i do hard sprints or runn my chest goes tight and i cant do much it also stays tight for quite awhile after and i cough up quite abit of mucus and find it hard to breathe what can i do i already went to a doctor for a ventilator doesnt seem to do alot
Hi Will great explanation, thank you. So my understanding- 1. The central chemoreceptors rely on high CO2 to stimulate breathing 2. Administrating O2 will not affect this central CO2 level b/c of CO2 retention theories you explained 3. So, in COPD patients being administered O2, the peripheral O2 dependent chemoreceptors in carotid and aorta are NOT activated, instead point 1 prevails. Therefore O2 administration is safe. Is this right?
Will, I deleted my original post. I wrote it after only watching the first part of your video and I apologize for my harsh words. Only after posting my message did the video get to talking about V/Q and Haldane effect and I realized my mistake. The information you provide actually is very well informed and presented in a format that is very understandable. I currently work in an institution which is very uninformed and not open to learning, this topic came up just this past weekend and I came across your video while trying to find information to educate staff. needless to say I was quick to judge and slow to listen. Thank you for spreading truth about this much misunderstood topic.
It is mostly due to an increase in dead spacing that is induced by supplementary O2 causing vasodilation, ''taking'' blood from well ventilated regions of lungs.
The hypoxic drive 'theory has always been taught to us in school. At least now I'm armed with better understanding of this and will not be afraid of titrating the O2.
The VQ ratio and Haldane effect can increase CO2 but probably there is something else here that is overlooked. As a RT I think it is often as simple as this. (I don't see this discussed anywhere which is frustrating because I hear RTs talk about knocking out drives all the time. Schools even caution, "there are some theories that too much oxygen may knock out the respiratory drive", which gives it validity as if it were true): Lets say a COPD pt ends up with CO2 of 50 and O2 of 50 as their baseline because the work of breathing would be too much to go down to CO2 of 40. THIS IS THEIR NORMAL BUT WE DON'T KNOW THAT. This pt gets pneumonia and the O2 goes down. They breathe faster to get more O2 so their CO2 goes to 45. THIS IS HYPERVENTILATING FOR THEM. We give O2 and their O2 goes up and CO2 GOES BACK TO THEIR NORMAL (back up to 50). Somehow we think we are knocking out their drive because the CO2 went up. NO. We are letting them get back to their normal. They are now able to rest. When the pneumonia clears up they'll be back to room air with the CO2 back at 50. No drive was knocked out. Would be easy to do a study (maybe someone has done it). On adequately oxygenated, intubated COPD pts, who are over breathing the set respiratory rate, turn the O2 up and see what happens. Should knock most or all of their drives out if the hypoxic drive theory is correct. I read once somewhere that there probably are some people (very rare) COPD or not, that do have hypoxic drives (I had one once), but it has nothing to do with COPD or any lung disease.
Can you make a video about difference of being a doctor and a nurse? Maybe tell us also why you chose to be a nurse instead of say ... a doctor or a pharmacist...
Didn't' realize this was still an issue. It's been a decade or so since I've heard anyone of anyone not giving O2 to someone who needed it.How about including the references you used to support your information.
Absolutely! It was always one of those dark rumors you heard about, just never knew if you could believe. I haven't personally seen this where I work but it doesn't mean it wasn't in the back of my mind when I first started school. Either way I think it's helpful to understand where the rumor comes from. As for your reference request: Abdo, Wilson F., and Leo MA Heunks. "Oxygen-induced Hypercapnia in COPD: Myths and Facts." Critical Care. BioMed Central, 2012. Of course I did additional reading to brush up on my knowledge, but the majority of my information comes from this article. Thanks for the comment!
Craig Button I'm in school for training in respiratory care. They tell you to give the patient O2 because giving tissue oxygen is the first priority. Just be prepared for COPD patients to stop breathing completely.
Will Wilson - so how do you correct the patient? I'm having this problem, I need to ween myself, my quality of life is diminished due to my overuse of oxygen.
Deborah adams I'm so sorry I'm just now seeing this comment!! Unfortunately giving medical advice without really knowing your situation would be a big no no and not something I would do. Just be sure to inform your primary of your concerns, best of luck to you!
I laughed so hard out loud when you said "jacked up". Thank you for making this simple and not so serious explanations.
I am cracking up as I am typing this HAHAH, I loer it though, Will, you are awesome :)))

When you're an RT reviewing from a nurse 😅 This really helped a lot That compliment on RTs tho. Thanks! 💛😍 Kudos to all nurses out there as well. 👊👊
Niz Jalil haha thank you so much! And happy (late) RT week! :)
Nobody will be able to understand a thing as long as they’re stating at the beauty and not able to focus.
Thank you for simplifying, I have been going over and over this trying to understand. Excellent video.
Love you! Great work editing!
Great explanation! I’m medical student and this video helped me a lot! Thank you! you’re really good at teaching actually!
Kudos to you 🥂
good explanation!

my clinical instructor also tole us that never over oxygenate pts with COPD, rather, give controlled O2 supplementation. IDK who to believe, helppp!!!
COPD o2 Should be around 92-93% purity
Very well explained 👍
Thank you. You just solved a question that has been bugging me for a long time.

Simple and clear, thanks
Thank you soo much for this video!! Why couldn't my teacher explain it like this? SMH. You're amazing!
how can i get rid of exersice incuded asthma verytime i do hard sprints or runn my chest goes tight and i cant do much it also stays tight for quite awhile after and i cough up quite abit of mucus and find it hard to breathe what can i do i already went to a doctor for a ventilator doesnt seem to do alot
Your good looking, good job with your presentation and best of luck in nursing.

Is this right?
is safe if you don't give too much oxygen and vasodilate the previously vasoconstricted pulmonary vessels, thus increasing shunt

plate454 I’m always up for constructive criticism but thank you for actually watching and correcting your last comment 🤙🏼
So simple, great job! Had to subscribe. Please, keep up the great job.
finally something that makes sense. thank you!
Emt student. Thanks for the video.

Super helpful! Thank you!
Great explanation...light bulb went off the first minute :)
life saver, Thanks for taking your time to this video!!
Allie Vasquez Absolutely!
an excellent way to describe thanks
Spot on my friend!
ASL RRT-ACCS
Well done
Thank you for making it all clear for me! :)
Miram E haha you're very welcome!
Will Wilson :) oh and btw, I passed my A&P exam!! Woof 🙄😵Thanks again! I'll be watching more of your videos!

Taylor loves the information
great breakdown thank you !!
make more videos!! this was so helpful
Thanks dude my teacher explained it and I couldn't get it. Understood your explanation first minute.
Nursing. Gotchya👌
Thank you
I’m an RN too but with him, I wanna be a pt.
Tf is wrong with u ?
Good info
Good job🙋🏾♀️
Is your name really Will Wilson?
Thank you for this video. Sitting in the ICU watching my mom on a Bipap machine they say, likely due to Co2 levels.....
You in respiratory school ?
Cant concentrate on what hes saying coz im distracted by his gorgeous face 😂
He is sooooo cute and smart
wow suddenly i love respiratory
Sasuke Uchiha haha respiratory is important!
Great explanation. Hypoxic Drive Theory is losing support in the facilities I work at
pleeeeeease keep on doing videos 🔥🔥🔥
You haven’t explained “drive”.
Can you make a video about difference of being a doctor and a nurse? Maybe tell us also why you chose to be a nurse instead of say ... a doctor or a pharmacist...
o2 sats not stats
jessica augustine good job 👏
good video 👍
n.m 1 thanks!
nice

Here in UK we are trained to keep 02 levels between 88-92% if COPD. In an emergency situation we would give 15L 02 regardless of copd or not
I cannot focus and smiling throughout this video. Going to report you!
I have heard of this haha! I waited for a whole year to understand this though hahaah.
How can you not be interested in listening to those lectures when he's so cute! 😄 I love when men are into smart things and into the medical field! 😁😄
flirt
🤣🤣🤣🤣🤣
You’re the best 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍
Its annoying to read the comments...nice explaining though. Sometimes its distracting cuz seem like flirting :S.
ohhhh he so cute. 😍
flirt
And that's about it.
Totally distracted ❤️.....
how do you expect me to focus on what he's saying when he's this hot omg
im learning and also im blushing huhuhuhuuuu
Brows on fleek
Sugar Hits 😂😂
Good information🖒,but reading girl's comments...🤣PRICELESS
Sunny Rastin haha truuu
👌💕
Oh my god! I'm in love. Smart and cute
What a cutie
You're hot. Lol
