Ninja Nerds!
In this lecture Professor Zach Murphy will be teaching you about Hypoxia. The term Hypoxia refers to a deficiency in the amount of oxygen that can be delivered to various tissues. During this lecture we will be discussing the types of hypoxia including hypoxemic hypoxia, anemic hypoxia, stagnant hypoxia, and histotoxic hypoxia, as well as the symptoms, diagnosis, causes, and treatments. We hope you enjoy this lecture and be sure to support us below!

Someone get this man a Nobel peace prize. Seriously. How many doctors has he made?
Just discovered this guy. Best teacher on youtube hands down. What a legend!!
Agreed, he really makes it simpler to understand. His lectures are the best
Legend indeed. I love when ppl teach like that.
Him and AK LECTURES. creating graduates. Lol
RIGHT??!!
His lucture......no words👌
Thank you soooo much, I had my exam yesterday and I got a full mark ❤️🙏🙏🙏
Allah bless you
I wanted to mention another thing... When you have emphysema, the elastic and collagen tissue in the lung parenchyma between the bronchioles is also destroyed via macrophages... What happens with that is that when you are trying to do a normal expiration the normal tension with elastic and collagen fibers is gone so as you are decreasing the volume of the lung... you end you collapsing the small airways... causing air trapping... hence an increase in co2 in these patients. Thanks for all the work you guys do!!
@Agam Agrawal When you airtrap... co2 cannot flow out of the alveoli-> bronchioles-> bronchi->trachea->pharynx out... it essentially equilibriates in the lung and blood... hence raising co2 and co2+h2o-> 2hco3-> h + h2co3 ... which will raise ph.
@Agam Agrawal 👍
Now if emphysema comes in exam, I am gonna nailed it. Thanks for info.🤞
@@adityakasodariya3456 Happy it makes sense;)
@@291ayl wouldn't the emphysema make the ph go down and make the blood more acidic
Thank you! Also want to mention that the percentage of O2 at high altitude remains to be 21%.
Yes
True, but the volume is lower.
Really love your videos, you have a great natural teaching ability. I dont mean to nit pick but at about 10 minute mark you mentioned the percentage of o2 changes at altitude , I think you mean the EFFECTIVE % of o2 lowers ( or PPo2) the ACTUAL percentage is the same as is the percent of nitrogen .
I was going to address this too. The proportion of oxygen (21%) is still the same, but since the pressure is lower at higher altitudes, the amount will decrease.
I wish all lecturers teach like you!!!
Ninjanerd never ceases to continue blowing my mind with content-- after learning about previous topics taught by him and then making the connections and remembering those other videos. THIS kind of content enforces retention of information. Mind = continually blown. Thank you, sir.
this man is saving me in my second year of medical school, god bless.
Love u maaaan.....really love you........u saved my life.....u saved me.....may God bless u
Great teaching! Excellent elucidations! Thank you. Keep on the good job.
But please, permit me to point out that the partial pressure of oxygen does not decrease at higher altitude because of a decrease in the percentage of oxygen, as you inaccurately mentioned at 09:27 of the video. The percentage of oxygen actually does remain the same, ie 21%, but the partial pressure of oxygen decreases due to the drop in atmospheric pressure itself at higher altitudes.
Thank you once again.
I agree. Excellent teaching, but maybe changing the words used from "percentage" to "partial pressure of inspired oxygen" would be better. Consider including a small addendum box.
@@shadiaconstantine9708 no...inspired is not a good adjective for oxygen...lol...you moron
Thanks Solomon Wai-Chu Wai, I paused the video there to research that thinking the same. But, like you said, "Great teaching". I look forward to watching more of Ninja Nerd stuff... as well as this one a few more times - lots of good info here
@@MusicLovingFool1 why are you so uncouth? What is the need for insult here? And even if she was wrong, you have no right to be rude where everyone is trying to learn. But she is right! Inspired oxygen is the right word got oxygen! Unless you have no clue of what is being discussed here.
Please, learn to be respectful on a public forum like this.
By the way, I want to say thank you for making these very value and well put together presentations available to the public. God bless you!
As always, awesome lesson!! If you could do a video about mechanical ventilation, that'd be amazing.
Thank you so much for this, it really helps me to finally understand the concept of hypoxia and its causes. Hope your pillow will always be cold on both sides and your phone charges in any angle.
Cold pillow on both sides! Most underrated blessing on TH-cam. A person with a cool pillow truly is blessed.
This video game me a lot of insight as to what type(s) of damage I got from smoking and snorting ketamine for 6 years. I've been to 9 doctors and a neurologist -so far none of them has provided me with a single point of advice on remedies and only one of them suggested that the problem could be hypoxia. This guy is super easy to understand, and its good how much he repeats himself so that people who aren't med students can easily pick this stuff up.
Love your videos! One note, saw this on another video too, at high altitudes oxygen remains 21% just the partial pressure changes.
I love his presentation skills. He makes every one to think in the way he does
Best Channel for Med Students Hands Down.
You're amazing!! I Absolutely love your teaching style. You are the BEST teacher on TH-cam. This was very helpful. My exam is around the corner and your videos are very informative. Thank U so much
Man I can’t get over how awesome you are as an instructor man! You just KEEP GOIN 👏 Thanks for the videos brother!
Always impressed with the quality of his teaching. Feels like my imaginary favorite highschool professor:)
هذا الرجل يصنَعُ مَجدَاً.🖤
God bless you guys..🖤🌸
Hands down sir for your extreme teaching talent.... ultra legend 💯💯💯💯
I like the way he explains with his drawings the effects of hypoxia
You hit the nail on the head with this one. Thanks for the in depth explanation.
Forever grateful to you sir. Thank u for making physiology simpler than we thought.😅..
Much appreciation
I absolutely love
The
Breakdown teaching as
A PACU nurse
These videos are so helpful, thank you!!
You are a gift to Humanity please Keep it up
Great teaching! reviewing for my nursing final and came across this. Lost me at the specific hormone science parts lol but it did help me understand all the types of shock. Thank you for doing an awesome job!
Very clear! Q: Do you have a video on why fibrin collects in the brain and how to control that or reduce the buildup which can lead to dementia. Thank you for your outstanding videos!
You are helping me so much! GREAT TEACHING! Thank you!
Ninja nerd marathon all weekend for physio shelf. Love these videos.
This guy is literally carrying us through medschool🥴thank you so much!
I am a nursing student and I must say your are a blessing n a treasure. Thank you for taking the time n making a difference. Loving all the videos very informative n incredibly easy to understand n remember. U sir have made my studies very easy. Thank u 💯💯👍👍🙂🙂
Felt like that vedio was only about 20 min like i didn't wanted it to complete,gr8 ved zach💪
making this topic so much easier to understand. thanks so much
Fantastic simple delivery of complex physiological subject. Hi
Simply awesome,well explained m glad I found your video cause I was overheating my head,but you helped .thank you
U make concept really easy to understand buddy
Thank u so much 😊😊
You taught very well sir you made it so easy.thank you so much sir
Because of watching this, I realize I'm actually at severe hypoxia and will be going back to the Dr. to seek immediate treatment. Thank you!
(I've been managing autonomic nervous system failure since I was young.)
Mary M get well soon dear!
Ahhh I’m doing so well in my physiology class thanks to you !!!
9:38 why does the oxygen percentage decrease and not the pressure? Many sources (including the one i follow) say its the pressure that decreases and the oxygen percentage stays the same
Best teacher, I have seen ever
you are a real hard-working teacher, thank you so much!
plz continue biology videos, there are so helpful
What a legendary teaching🤗...
i dont have words to describe...it was super amazing.......
You are great at simplifying stuff.Fantastic
Awesome video 👍🏾very educational and so informative. Have COPD and been medically mismanaged for years.
I am so thankful to come across your video on hypoxia as it has given me an understanding of my condition and why I'm breathing but feel like I'm not getting air.
Great content and easy to understand 😁👍🏾
Sir , little bit confusion here
Carbon monoxide poisoning is type of anemic hypoxia.
I had read about this.
Your way of explaining is very fantastic.
Thanks for this awesome video
I learned a lot of things by this video 👍👍👍👍👍👍👍👍
yup, guyton hall states that co poisoning is a type of anemic hypoxia which makes sense because you basically have low hemoglobin and low O2 carrying capacity
@@adnanfouad5298 The hemoglobin is not necessarily low. The concentration of oxygen within the hemoglobin is low, being replaced by the CO, which binds to the hemoglobin at a much greater rate than oxygen.
Thanks sir easy to understand 😌
😃
Greetings... l must say you are in depth and accurate...thanks and God continue to use and guide you.
Super teaching to understand topic
Each and every video by him fantastic - crystal clear explanation, kudos bro 👍👏👏🙏
Wow this one is so densely packed with information lol
Tq so much.It's really helps me to understand this topic since i'm just keep going to attend lecture through video(Unibersity closed),it was a bit complicated to me
gives me a better understanding of th hypertensive emergency ,hypoxiic event I had
Namaste Doc, Your presentation has helped me a lot in understanding my personal so a big thank you and Om Shanti.
The moon on my fingernails turn bluish/purple so I started taking Hawthorne extract. My heartbeat per minute went from 50 to 65. It worked!!! Don't take it for long periods of time. Just a few weeks. Check your heart rate and start taking again if needed. It works for fast and slow bpm. My doctor's have failed me. He told me that a 50 bpm was good. He said athletes have 50. I'm a 60 yo woman. Not "athletic". It's a good thing doctors like this are available to us. They are saving lives all over the world through their generous spirit and wisdom.
sir u r the best teacher in the world
The final cascade (pathogenesis) of resultant hypoxia-driven apoptosis is this.....
1. The phospholipase itself causes damaging rot into the cell wall (because the cell wall has a phospholipid structure), leaving obvious demarcations in the cell, allowing the blood to go into the cell to cause further damage.
2. Finally, leaked calcium can penetrate the mitochondria, and, like lysosomes that got rotted, the mitochondria also rots, allowing the cytochrome C molecule to be released out of the mitochondria, and hit the cytosol wall of the cell.....and this means big trouble for the cell itself, because when cytochrome C is out in the open, it is like pressing the self-destruct button to that affected cell.
3. Then apoptosis finally results - and THE CELL DIES!!!
i appreciate your videos so much. thank you for taking the time to make them
you made this easy to understand.....................thank you very much
wow...very nice teaching skill...love from india ♥️
9:28 percentage of oxygen is the same regardless of the altitude?
Love from India 🇮🇳sir...a bigggg thank ❤you from us
This guy is the best, Tyanks.
+wildlife T-shirts thank you so much. I'm so happy that we were able to help!
The newest therapy from Germany: Vital Air 5+ device !
Thanks!
Wonderful explanation. Thank you so much.
Hypoxia due to bad asthma attacks. I lost consciousness, passed faeces and had to be resuscitated almost every time about 10 times a year for about 5 and a bit years. Leaving me after each time with burst blood vessels on my face and eyes and loss of sight for a few hours. It happened between my teen years. I got prayer healing and was blessed. I had a mri scan for my brain three years ago after an accident which showed that i had had several strokes not tia. Dead tissue. They said there was nothing they could do.
Can't say thank you enough
As you go higher altitudes, the percentage of oxygen doesn’t change instead since the pressure decreases the partial volume of oxygen also decreases but it still is 21 percent of the air.
u r my guruji🙏
Amazing drawings and great explanation keep on DOING GREAT ❤❤❤
At high altitude, the percentage of oxygen remains the same. Still 21% of Oxygen and still 79% Nitrogen. But the density of Molecules of oxygen decreases as well as the density of molecules of nitrogen decreases. As the density of the molecules decreases so they exert less pressure in total. Eg at 15000 feet, the atmospheric pressure is 429 mmhg. Then you take 21% of 429 to have the partial pressure of oxygen.. about 44 mmhg. Too low for the human being who needs a min of 60 mmhg of pressure of oxygen. Well you could still think a bit for about 20 minutes before developing the symptoms of hypoxia.
Alex Wonner yes i do agree....nevertheless i liked the lecture
thats right...
Im pretty sure he meant the ratio of oxygen to total volume of gas remained the same but the PO2 decreased because the gas pressure at high altitudes decreases.
Check your math...hard to take your answer with any legitimacy when you mess up basic math. 21% of 429 is 90.09. People are using these videos to earnestly try to learn, so if you dont know what you're talking about, then don't chime in. If you do know what you're talking about (and I'm perfectly willing to give you the benefit of the doubt), get it ALL right. Dont be sloppy because accuracy matters.
Thank you sir Zach for the amazing lecture and the team Ninja Nerds!! All love and support!! ♥️
Very good helper thank you ninja👍👍
Remember HASH- thank you Thomas Petty, MD! A great teacher.
The H is hypoxic
Thank u for explaining it so clearly!!
Thanks a lot man, really helped me understand and memorize
Youre absolutely brillient
Nicely explained
Many thanks
I thought you were brilliant on this video. You didn't oversimplify anything and o found it very useful for my revision. I am studying for a nursing exam in the UK. Thanks! 😊
Really appreciate your videos.

I knw i m late to saying this bt u r perfect with teaching style n (looks too) ninja😌💜💙
Amazing teacher!
I have such a great teacher, thank you!
So ground glass nodule obstruction would mimic emohaseme in the gas exchange? Correct? It doesn’t allow for full exchange but does allow for saturation.
