For Beck's triad I always remember it as "JVD, Low BP, Decreased sound activity (muffled)". It rhymes. Working along side medical residents they always had some sort of rhyme or sentence/phrase to help them remember stuff.
Tracheal deviation is a late sign of tension pneumothorax, muffled or absent lung sounds, and difficulty ventilating the patient would both be earlier signs, along with decreased 02 saturation and narrowing pulse points.
Oftentimes tension develops rapidly and early recognition would be in identifying pneumothorax prior to tension, although this may be abrupt as well. Once tension pneumothorax is present, its life-threatening as cardiovascular collapse is our concern and it is often accompanied with severe dyspnea, respiratory distress, hypoxia, tachycardia, hypotension (often profound), diminished/absent breath sounds, expanded chest wall, and tracheal/mediastinum shift. JVD and cyanosis can also be present. While narrowing pulse pressure may be present it isn't a defining characteristic of tension and more often associated with tamponade, therefore the aforementioned S/S are most telling.
Haha! Oh boy, there are other mistakes out there in other videos. *face palm* I really focus and try now to make sure I catch and fix all of them. I do appreciate the kind words and glad you like the videos!
Mechanical valve obstruction due to thrombosis adds up to the list of causes of obstructive shock. I've been wondering though, why aortic dissection is usually listed as a cause of hypovolemic shock instead. Can anybody help me understand?
Hi Eddie.... I first want to thank you for all of your amazing content!! You are an excellent teacher and I encourage you to continue to share your knowledge. I will be graduating from nursing school soon and consume tons of TH-cam content, but your material has recently become one of my favorite Critical Care resources. For curiosity sake, I have a quick question about the subcategorization of Cardiogenic/Obstructive shock. You mentioned that one subcategory of Cardiogenic shock is structural or valvular. Is this limited to regurgitation? I guess I'm wondering why Aortic stenosis is subcategorized under Obstructive, rather than Cardiogenic..... or perhaps this is just semantic?? Thanks again for all you do and I look forward to watching more of your material as I enter my final semester of school.
Hey Justin, thanks for stopping by to leave a comment and question! I am honored that you have enjoyed these videos so much. I definitely will continue making more videos for sure. So many critical care topics I have yet to even address! As for your question, I would say depending who you ask it may just be a matter of semantics. As I had said, some people don't recognize obstructive shock as its own separate category and just lump all the causes in with cardiogenic shock. If we were to consider all causes as just cardiogenic, then aortic stenosis would definitely be considered a structural cause. But for the sake of clarity and understanding, I believe thinking of the obstructive shock as a separate category helps with the understanding of what is causing our pump failure. Here we have several issues that are obstructing blood flow. PE obviously blocks the vessels, Tension PTX does so by putting pressure and limiting the heart, in a similar way that restrictive pericarditis does as well. Then finally AS is obstructing the outward flow of blood from the LV. Where as MR is not obstructing flow, it's just a structural issue that leads to a diminished ability of the LV to move blood forward as some portion of that blood is now moving backwards in the system. I hope that explanation makes sense! Let me know if you have any other questions and thanks again for watching and supporting this channel!
Doesn't the valve in the right atria have three leaflets and the valve in the left atria two? I'm confused about the valve names because there are three tricuspid valves (three-leaflet valves) and one bicuspid valve, called mitral, correct?
Доброго времени суток! тут такой же крутой контент как у меня, такое редко увидишь в наше время Надеюсь ты сможешь так же оценить и мой канал, с роликами на разные темы и вкусы.

As an EMT fresh grad, thank you for making these videos :) They are highly detailed and informative, love from Singapore!
I never really got the concept of negative pressure surrounding the lungs but in the way you explained it It makes so much sense, thanks!
Yay! Happy to hear this!
Thanks have now understand, have been following this lecture since from part 1.
Awesome! To this day, I am still really happy with how this series came out! Glad you have enjoyed it.

Informative ❤
I thought Beck's Triad was two turn tables and a microphone. I learned something new today.
*rim shot*
Thanks !
I’m glad you corrected yourself on the PA! We were gonna have to have a talk! Lol! J/K love your videos! Nobody’s perfect but you’re pretty close 😍

I use your video to get me to sleep. Your voice. .
I'll take that as a compliment? haha

Can you please tell the reference books..so that I can add book name as a reference in my seminar

Thank you I have not The text needs to be enlarged and be clearer
Yeah, I've had others mention this. It's something that I actively work to improve.
