This sock method have turned that lesson into a legend😂🏆
Thank you so much 😊
For sure 😂
A- emphysema
B-normal
C-amiodanon and bleomycin
You seriously have a gift. Not only do you explain concepts in such an easy way to understand, but you are hilarious too! Reading my class physiology respiratory notes for hours does not compare to even 10 minutes of your pulmonary videos. You were totally born to do this. SO grateful I have access to your videos. I 1000% attribute my success on exams to your channel.
Wow 🤩
I am honored!
Good luck 🍀
@@MedicosisPerfectionalis Same honeslty. I am a med student and we have had consultants, prefessors etc explaining it to us, and I never understood the compliance until I found youuuuuu. Thanks so muchhhh
"And there is another organ that has compliance, but let's keep it clean" 😂😂😂 I died
Haha 😂
😂😂😂
😀😀😀
A.emphysema(bcoz elastin is destroyed so there will be more compliance)
B.Normal
C.Amiodarone and bleomycin(bcoz it causes pulmonary fibrosis which increases elastic recoil)
🎉
Amazing! Loved your sock example and you're so easy to understand. Thank you. You deserve more subscribers and views.
Thank you so much 😊
Can you please help me by sharing?
@@MedicosisPerfectionalis Hey! I was wondering why volume increases with pressure in the lungs when talking about compliance, but according to Boyle's law pressure and volume are inversely proportional?
...and by the way, those who don't like socks they can use underwear as example hahahha I love Medocosis!
Yess😍
i didn't expect you will made it easy like that . Props to medicosis
Thank you so much!
Oh my god! You blew my mind with this.....never in my life I understood lung compliance but after this video I surely can never forget it👏👏
I am so glad!
Thank you 🙏
No one teaches with this much humor😂. Everything from RLD, OLD to compliance was so perfectly explained. 👏👏
Can you explain why the compliance during expiration is higher than inspiration? Is it because of the surface tension and elastin?
You're an amazing teacher.. First 2 minutes of lecture was enough for me to get the concept. Thx a lot.
Awesome 👏
Thank you so much 😊

This is the first time for me to understand lung compliance .thanks a lot.egyption doctorجزاك الله خيرا
You’re very welcome 😊
"If you don't like socks, then you can do from underwear like if you're into these things" omg I lost it haha :p
Haha 😂
😂😂😂
R U still a student ?
I am loving the examples! I wish my professors could teach like this!
Thank you so much 😊
This is way better than those horrible lecture classes my prof took
Thanks a million!
This is what I love to hear :)
dang this video legit provides the ultimate answer to my spirometry report. Thanks heaps!
You’re very welcome 😊
A....emphysema
B- normal lung.
C- post chemo( bleomoycin) or amoidarone induced fibrotic lung
Must watch video for every medicos......you are amazing ....love from india
Thank you 🙏
Fantastic video! Thank you
My pleasure!
Amazing explanation man
Even my coaching classes were not able to explain like this.
Thank you 🙏
Wow, thank you so much doc! You explained this so well & I really enjoyed the socks analogy & other humor lol.
I think the graph answers are: A) emphysema; B) normal; C) Rx treatment
Thank you so much again!
Glad it was helpful!
Excellent explanation ❤
Glad you liked it!
Thanks from Egypt ❤ جزاك الله خيرا
My pleasure 😇
You too!
You are a funny guy.😂
Thanks 😊
favorite medical channel yes
Thank you so much! It means a lot to me!
Would you please help me by sharing my videos with others?
Your... Explanation and your teaching skill are awesome👍👏... Thank u sir
My pleasure 😇
Thank you 🙏
You’re awesome, I wish you’d add the topics in the description box with the corresponding minutes to make it easier to look for specific topics
Thank you 🙏
Man! Can you make your introductory video I really love the way you explain
Amazing video, probably the best
Thank you so much 😊
I appreciate ur sense of humour too😛 along with your lectures👍
Thank you 😊
A. Emphysema
B normal
C. Amiodarone/bleomycin..but I don’t know how these drugs decrease compliance
They cause a restrictive lung disease...Please watch the following videos in the Pulmonology please!
Thanks 🙏
they cause pulm fibrosis
-2 is greater than -6,so how u can say that it's smaller
In pulmonary fibrosis the lung compliance decreases
But elastic recoil doesn't increase
In fibrosis it is more of collagen fibres
Total no. Of elastic fibres are reduced by scar tissue(collagen)
Collagen fibres have high elastic modulus which means they are resistant to stress (stiff)
Due to that reason compliance is reduced in pulmonary fibrosis.
Brilliant, truly! Thank you!!!!!!!!
Good job you're make the easy way to understanding
Medicine makes perfect sense once you know what the hell you’re talking about, 👌
Thank you Dr. for this exceptionally well explained video. You should be giving classes in Harvard or Yale - you really understand medicine and have a gift for explaining it to others. I will always picture the sock 🧦 example ….
Also your Sympathetic and Parasympathetic videos are beautifully easy to understand
God Bless and thanks again
God bless you too, Daniel!
Thank you 🙏
Perfect,thank you doctor ♥️
My pleasure 😇
U r really amazing
But in the pressure volume curves..the pressures are negative...there fore -2 is greater than -4(13:09)
And even in the previous example...hope u clear my doubt
Thank you
Here minus sign just tells about the direction of pressure , thats y i think
@@pallavipatel5387 okay.. thank you...😊
Thanks a lot!! U make the concept so easy to understand 👍
Best ever explanation ❤
Thank you 🙏
Who are u! I been cracking head about this for a very long time. Thank you so much. Sock rules!
Haha 😂
Thank you 😊
You insist on making me excited 🤩🤯
Thank you ❤️
شكرا 🥰

Your videos are so good that my professor redirected me here instead of doing the explanation himself 5/5
Haha 😂
I hear that a lot!
Thank you so much for watching!
Say Hi to your professor!
Amazing! i interested the way you teach and by providing so many examples and good approaches in order for me to understand it well. coz for me this topic was kinda lil bit difficult to understand but u're making it in fun and easier approach.
Thank you 🙏
Question
A ephesyma
B normal
c alverdorne ....
In calculating DELTA V/DELTA P, does we consider negative sign or just magnitude???
thanx man u give the best mneumonics for this theme )))
My pleasure 😇
Loved your analogies and the synonymous table. Great job man! Better than anyone else who tried to explain it
Thank you so much 😊
I am honored!
Can you please help me by sharing?
Concerning the curves, won't the negative value of the pressure affect the ΔV/ΔP value hence making inspiration have a higher compliance because of their negative values?
Sir u r really really just AMAZING........ thanks a lot dear sir🙏🙏
You’re very welcome 😊
if I had to choose only one youtube channel which I could watch, id choose this one
Thank you so much 😊
Great explanation as always !! very fun to learn from you
A emphysema
C amiodranone which cause pulmonary fibrosis decreasing compliance
God bless you.
In addition to the opposing forces,lymphatic drainage of the pleural space also contributes to the negative intrapleural pressure.
Awesome video as usual 👍
A is emphysema
B is normal and
C is amiodavone and bleomycin
Thank you!!!!!!!!!!
My pleasure 😇
Awesome teaching!!!!
Thank you 🙏
Amazing!
Thanks 😊
Can you please help me by sharing?
Is Asthma a COPD disease?
I thought that
- Asthma
- Cystic fibrosis
- Bronchiectasis and
- COPD (Emphysema and C. bronchitis) are together called Obstructive lung disease and COPD diseases include only Emphysema and Chronic bronchitis
Thank you 🙏
It's just amazing
GREAT!!🙌
Thank you so much 😊
thank youuuuuuu
Sir you are just awesome 👍
Thank you so much 😊
please please make lectures about cardiology
thank you very much
In pulmunary fibrosis, shouldn't both compliance and elasticity decrease?
That u so much for this!!!
My pleasure 😇
"And. You. Arr. Increasing your compliance, baby". Lol that got me.
Heheehe
A-emphesema, B-normal, C-fibrosis
A- Emphysema (larger angle, more volume, increased compliance)
B-normal
C-Amidarone and Bleomycin ( Induced Fibrosis, decreased compliance)
amazing!! thanks
My pleasure 😇
medicosis why does the expiration have a higher compliance while it works to get the air out? so we need elasticity for expiration to happen no?
Thank u man!
My pleasure 😇
Can you please help me by sharing?
Great video! Thank you!
Just One question ! Doesnt the expiration reflect recoil? Can we talk about a compliance in expiration ?
Please kindly explain to me why lung compliance is more at base and low at apex?
Thank u 🙇
My pleasure 😇
Really a very gud video
Do the gud wrk forevr
Thank you so much 😊
I have a question, so how does this compliance relate to administering continous positive pressure to a obstructive versus restrictive pathology?
At 8:45 you say the saline filled lung has less recoil tendency hence less negative intrapleural pressure, doesn't that mean less air gets in the lung. But then down the page you say a patient with alpha-1 antitrypsin deficiency leads to decreased lung recoil which increases lung compliance and so more air gets in
So I'm confused, how can less recoil cause more air to get in the lungs in one scenario and less air to get in the lungs when both are as a result of less recoil
man I love you thank you
Thanks a million, dear :)
So helpful ⭐
Thanks 🙏
If compliance increases then elasticity decreases or increases? & Also resistance increases or decreases? Plz help me with this one brother. Thnx in advance
One point i couldn't get why expiration has more compliance where as lungs recoil at that moment?
perfect.
Genius.....
Thank you 🙏
Hey @Medicosis Perfectionalis I was wondering why volume increases with pressure in the lungs when talking about compliance, but according to Boyle's law pressure and volume are inversely proportional?
If you don't add externally pressure, the increase of volume will decrease pressure. If you add pressure directly to the lung, the volume will increase.
@@greencamixx can you please explain ?
This is bomb! Subscribed!
Thank you so much 😊
I am not getting this why not during inhalation as we r expanding our lungs so compliance should be more and while exhaling we r recoiling
Same question
Amazing
Thanks 🙏
why more compliance with expiration? in expiration we have more recoil and recoil goes against expiration, no?
against compliance* sorry
It’s related to the surfactant.
ur a amazing 🔥
Thank you 🙏
What about the compliance in chronic bronchitis, bronchiectasis and Asthma?
Increase=higher TLC and RV
Damaged elastic tissue.
Or
Decrease=collapse and atelectasis.
Thank you in advance🌷
Chronic bronchitis and bronchiectasis might have increased compliance, high RV and TLC.
Asthma has normal values (except in later stages of chronic, severe, persistent asthma which is very similar to COPD).
If any of these conditions caused atelectasis, then compliance will decrease and so will the RV and TLC.
Hope it helps!
Yes,it helped alot.
Thank you,doctor!💕
My pleasure 😇
You are smart and funny, thank you
Thanks 😊

A-Emphsema
B-Normal
C-amiodion and bleomycin
If compliance is expansibility then during inhale it should be more as compared to exhale plz anybody want's to discuss
Expansibility is not the same as expansion (similarly, conductivity is not conductance, and resistivity is not resistance).
Compliance is not about expansion, it's about deformation (STRAIN)produced per certain amount of STRESS.
In case of lung physiology the deformation (STRAIN) is measured in change in volume/original volume.
STRESS is that which causes that STRAIN (change in volume) and is measure of Trans pulmonary pressure
[intra alveolar pressure(IAP)-intra pleural pressure(IPP) ]
The actual formula for compliance is strain/stress.
Strain= change in volume/original volume
Stress= trans pulmonary pressure
Now into your question
Even after expiration lungs still have functional residual capacity of 2500ml air inside all alveoli.
So even before inspiration the volume of air in lungs is 2500 ml which is V1
Now after normal inspiration (tidal volume) of 500ml the total volume of air now in lungs is 3000ml = V2
Change in volume= V2 - V1
That equals to (3000 - 2500)=+ 500ml
That positive sign indicates the stress is tensile and is stretching in nature.
Now come to strain
STRAIN = change in volume/original volume(V1= 2500ml)
Calculate it
STRAIN = 500/2500 = 1/5
Now STRESS= trans pulmonary pressure at end of inspiration { Tpm}
Tpm = IAP - IPP
At end of inspiration IAP = 760mmhg
IPP = 754 mm hg
So Tpm = 760 - 754
Tpm = 6mm hg
Now come to compliance
C = strain/ stress
C = 1/5×6= 1/30 [ml/mmhg]
The inference is for a stress(pressure) of 30 MMHG the strain (deformation or volume change) is 1ML.
So for inspiration the lung compliance is 1ml per 30 mm hg
Now let's calculate for Expiration
Before expiration that is at the end of inspiration the volume of air in lungs is 3000ml
Now V1= 3000ML
And now stress is elastic recoil of alveoli which increase pressure and produce change (deformation)
After normal expiration (T.V) of 500 ml the final volume V2 is 2500 ML
So change in volume is - (V2 - V1)
The negative sign indicates the elastic recoil of alveoli is of compressive stress
So change in volume is - (2500 - 3000)
U will get 500ML
Now for strain = change in volume/ original volume
STRAIN= 500/3000 = 1/6 (no units)
Now for stress (Tpm)
Tpm at end of expiration is IAP- IPP
IAP at end of expiration is 760 mm hg
IPP at end of expiration is 758 mm hg
Tpm = IAP- IPP
Tpm = 760 - 758 = 2mm HG
Now for compliance C
C = strain/stress = 1/6×2 = 1/12 [ml/mmhg]
The inference is for a stress of 12 mm hg the strain is 1ml
So during inspiration for producing a change in volume of 1ml u need 30 MMHG
But in case of expiration for producing a change of 1ml u just need 12 MMHG.
Final take = for a very little stress if we produce more change it has more compliance
Compliance of lungs is higher in expiration than in inspiration bcoz in expiration a less stress(pressure) produces more change in volume
That's it
If u make it up to here
Good luck for ur future
What if my university teacher can teach me like this💔
Great teacher you are❤
Thank you so much, dear :)
I am so happy that my videos are helping!
