My goal is to reduce educational disparities by making education FREE.
These videos help you score extra points on medical school exams (USMLE, COMLEX, etc.)
For educational purposes only; NOT medical or other advice.
Some videos contain mild profanity and hyperbole solely used to assist with memorization. Viewer discretion advised.
Opinions are entirely my own.
In summary
O2 sat - increased in only septic
CO - increased in only septic
PCWP and CVP - increased in only cardiogenic
SVR - decreased in all 3 types of distributive
HR - decreased in only neurogenic
Cardiac tamponade(obstructive) being an exception with increased PCWP should also be added just for completion sake :)
Anaphylaxis and neurogenic should be labeled ⬆️ for CO.
The confusion comes from the stages of distributive shocks.
Initial stages - CO increases (due to compensation)
Later stages - CO decreases (compensation is exhausted).
--> Most text books show the early stage effect with the arrows going up ⬆️ (Google it).
Best lecture on " shock " I have ever heard !! May God bless you with all HIs grace.
2 Heads ups:
if you get a weird question with warm extremities and increased PCWP, the PCWP is more specific for cardiogenic shock than anything with extremities.
Same goes for temperature. Body temperature can be super low and extremities can not be warm, but O2 sat or CO is increased, the answer is septic.
Thank you so much for your dedication to medical student education! I discovered your channel 2 weeks before my STEP 1 exam date and binge watched almost all of your videos on 2x. You definitely earned me many "free points on test day!" Completely overjoyed with my score! Thanks again 🙂.
you probably dont give a shit but if you're stoned like me during the covid times you can watch pretty much all of the new movies and series on InstaFlixxer. Have been streaming with my girlfriend lately =)
@Isaiah Reuben definitely, been using InstaFlixxer for months myself :D

That's how to do it lol. All my friends did the same every single one of them lol
Howdvyou do
Add Obstructive shock to the list! (Massive pulmonary Emb. causing shock) Then you get the Mnemonic NACHOS, and you can surf 3rd year, never forgetting the types of shock 😁
Good point!
What is NACHOS stand for?

N: Neurogenic
A: Anaphylactic
C: Cardiogenic
H: Hypovolemic
O: Obstructive
S: Septic
@@user-ul2sd8yc3g thank you so much
Where in the initial flow chart would that be?
This is by far the best explanation to shocks, you're awesome man thanks a lot
This is by far the best explanation i have come across on the topic. Thank you!!
This is the best lecture to date. Please more. 🙏🏾
EMT here. Recently completed a class, NREMT stuff coming up. I ran through some coaching materials and realized I needed to review the pathophys of shock. Your video helped out a lot with refreshing what I needed to know at my provider level about shock, and then some. And then quite a bit more, actually xD
The reminder that hypovolemia could have non-hemorrhagic causes was one I definitely needed; same for the realization that septic shock was actually pretty easy to explain
Could you please make a video on lipid lowering agents? I think it would tie really well with your biochemistry lecture on lipids. Thanks
May God always bless you with THE BEST in your life !
The best explanation of different types of shock!!!! thank you!
Thank you so much!!! You're amazing and your videos are so clearly explained
Best explanation I have seen for shock. Cheers
You are Awesome Sir. Thanks a lot... respect and appreciation
THANK YOU SO MUCH!!! This video is so simple to understand! I LOVED IT!!
Woow, amazing explanation! Much better than my lectures! Thank you for making it easier to understand!
YOU ARE AMAZING!!! Thank you so much for the great explanation. cardio concepts make so much sense after watching your videos
Please cover high yield Microbiology..Your videos are a Blessing to understand key concepts,ECG stroke and Biochem Series helped immensely..You really chop off the unneccessary fat that no one needs but sadly is a part of every resource..ECG is always made so difficult by everyone that by the time you reach the juicy part,you've lost focus completely..For exam purpose ECG must be taught like you do
bruh just do sketchy
Great Video and extremely high quality!!
I got rolled by almost every shock question in UWorld so thank you based dirty
thanks you so much for great lessons
this was incredibly useful!
This was the best explanation for all the shock, thank you so much ☺️
First aid says cardiac output increases for sepsis and anaphylaxis
Can you make a pharmacological video on blood thinners? I think it would be really useful
Thank you Sir for such amazing video.
You forgot about Obstructive shock including PE, Tension pneumothorax, and Cardiac Tamponade? Others than this, your videos are excellent. Thank you so much!
Excellent video, thank you❤
just in time to understand this as I am going to write my mccqe1 next week and I had trouble understanding this .Thank you very mch
Thank you so much 😭😭😭 best explaination
Can't express just how grateful I am for this channel and your dedication to making your resources accessible to all. Thank you for getting me through my home stretch of Step 1 dedicated!
Thank you for the video
Thank you!
Thanks!
this playlist is goated
This literally makes shock so free.
Re-uploaded with one minor correction. Carry on :)
Whatcha think of my addition?😂 i was sooo happy when my professor in pathophys randomly mentioned Obstructive shock, and i had to ask if its really a thing! Finally my "NACHS" was complete, into NACHOS 👌
Almost put ME into shock there for a sec cause I was mid- video LOL. Whew. Can you make a video covering endocrine? Like all the stimulation/suppression tests for cushing's, ACTH, insipidus, etc cause those are really confusing and maybe one on all the hormones and their effects (especially big ones like insulin)
Please can you do the Km and Vmax video they removed it..my friends and I love your videos and we noticed that they removed this one..please can you fix the problem..thank you very much you are the best
Can you please re-upload the vaccination video
Can you please re-upload the diabetes video? It was so good but I just noticed it was removed
Thank you
Thank you so much
Absolutely love your explanations 😍
another great video 👍🏻
Thank you that was amaizing
Thank you ❤️
so useful thank you
Thank you Sir
thnks
Cardiac tamponade is the same as obstructive shock. Other types of Obstructive shock ( pul embolism etc) are same too except low PCWP and increased SV02. hope that helps!
This is picture of early septic shock , because later on when the septic shock progresses , reduction in cardiac output occur.
Increase in Oxygen sat ( mixed venous O2 sat ) occurs because high blood flow rates in septic shock do not allow complete extraction of O2 by tissues so sat increases.
Mixed venous oxygen is O2saturation in this vedio
Great video
U r excellent...
How about Obstructive shock, you did not discuss that? Otherwise excellent presentation.
Great pathophys explanation! Quick and dirty just like my...
helpful for neet pg also thank you
شكرا
fav video on yt
Sir can u please make video on various genetic terms given in genetic section of First aid? Thank you
you are a hero
I got one question from this video in my real deal..
Thank you dirty..
so on uworld- it said for cardiogenic shock that the PCWP is decreased bc left sided filling pressures are reduced
Nice 1 lectures plz next Lecture with adde.....
Management
first aid seems to say that anaphylaxis increases CO, not decrease like you have in the chart
I was going to say the same thing
Woudnt compensatory mechanism of increasing SVR in cardiogenic shock make things worse? I mean if the SVR increases then the blood can't go out from the heart into the blood vessels. Wouldn't that make things worse?
Precisely. Hence the reason shock is so serious and is a rapidly deteriorating cycle if not treated
Thank you so much. I understand the concept now
In nursing school right now 😂...l love this
What about the explanation for obstructive shock?
when we say PCWP, what do we mean? the pulmonary veins? or the left atrial pressure?
Left atrial pressure
Cardiogenic - CO DOWN only
H(R)ypoSvRolemic - HR and SVR UP only
Neurogenic - everything DOWN
Septic - COHR UP only ("COHRUP")
Anaphylactic - HR UP only ("HRUP")
O2 sat down except for Septic
Love u man!
I love you. Thanks
in hypovolemic shock -- shouldnt the HR and SVR be increased in response to a low CO ?? low CO compensation is increased HR .. and baroreceptor activity causing smooth muscle contractivity by releasing norepi .. thus SVR should be increased to bring up or equalize the hypovolemia state no??
is there any pdf for each system?
why is cardiac output increased in Septic shock and decreased in other types of shock?
god bless your sole
what about pulmonary embolism? couldn't that be a cause of shock?
re upload?
oxygen sats down for hypovolemic shock due to water loss?
Hi Dirty (and everyone :) ) - does anyone know if there's a video on TORCH infections? Maybe I'm missing something
i dont currently have one, but maybe soon!
@@DirtyMedicine Gotcha, sounds good! Thanks so much for replying!!!
Hey CO in anaphylactic shock is increase 🙂
Anaphylactic shock increase CO.
Doesn’t O2 saturation increase in all of distributive shock types as they are all high flow states which doesn’t allow complete oxygen extraction ?
Except neurogonic shoch
Isn’t CO increased in anaphylaxis
3 : 00
I would very much like to hug you
Respectfully
Obstructive Shock: ↓CO, ↑HR, ↑CVP, ↓PCWP (Except Tamponade ↑), ↑SVR, ↓O2 Sat. Is that correct?
So I'll go over this 50 more times lol
I've proff tomorrow and ngl this topic scares me
Hows ur exam going on ?
oh dirty, you're too good to us TY
2:52 Shock & its types
6:33 Cardiogenic shock
10:17 Hypovolemic shock
13:04 Distributive shock
love from Pakistan
more hard topics
i love u
I just created a good nemonic here: distributive shock are SAN, septic, anaphylactic and neurogenic, same as SAM which is a distributor of food in supermarkets 😅
太强了
О-о-о, какие люди!
я тоже пытаюсь снимать крутой контент как и у тебя
зацените, когда будет время

an osmosis advertisement on a dirty video? the audacity
You dirty you..
Thank you
