In this first lesson on shock we answer the question, what is shock? We cover all the basics that you need to have a good understanding of what this medical conditionally really is.
In addition to that we take a deep dive in to the shock pathophysiology rabbit hole! We provide a very detailed and thought out explanation of the physiological processes that our body experiences as we find ourselves in a state of shock. While this is quite detailed and complex, we do our best to make this as simple as possible.
Finally, we cover the signs that you would expect to see in a patient who is in shock. These are very important things to recognize in your patient as they can mean the difference between life and death.
Our biggest hope for you to takeaway from these lessons is to understand that shock is a LIFE THREATENING situation for your patients and that quick recognition and intervention can mean the difference between life and death.

Essentially, the chemoreceptors are specialized receptor cells that can detect chemical changes in the blood. In the shock state, these chemoreceptors would detect a decreased pH, a decreased supply of oxygen, as well as an elevated level of CO2. This would trigger the respiratory system to increase the rate and volume of respirations in order to try and compensate for these changes.

One of the benefits I offer to one of the Patreon membership levels is audio of the lessons.

[@kamala3428]

Hi Eddie, I love your lessons and learning from your channel. I am wondering if it’s possible to have the lessons on the slides or pdf as well. So that I could print and read when I do not have access to online lessons. You are doing such an amazing job helping out the new ICU nurses. Thank you so so much!

Hey hey! This video was so good. I'm busy doing an assignment on septic shock and this helped me understand the concept. If you could be so kind as to provide a reference list - I would like to research further and reference the information - particularly the increased HR pathway. Thank you so much!

I'm glad that you enjoy it. As for references, I use various critical care books as well as a combo of personal experience when I do these videos. AACN Essentials of Critical Care has a lot of great info if you are looking for just 1.

I'm never going to do anything with this information ever over the course of my life, but it's really cool that this is available for free online. I don't think knowledge should be kept behind paywalls and restricted to people born into wealth (people who can afford college).

[@muhammedhassan5945]

thats an extremely helpful explanation of a complex subject.. I really appreciate your job .. note : at 16:35 you mention that renin is released by the adrenal gland .. we know it released by the kidney ..

[@futurernari5901]

Good catch! The Juxtaglomerular cells in the renal glomerulus primarily store and release renin, related to the afferent arteriole pressure

[@therunningmonk6428]

Wonderful educational video ..very informative ..thanku from india ..I am a runner and more opwerful reason to train aerobically and imbibing high fat diet ..I hope I can associate this knowledge in my training and nutrtion to the peolle whom I train and to myself..thank you once more ..gratitude

[@mohamedelmoghazy2981]

Thank you for this very informative easy detailed video. I have a question, why there is ST elevation in shock state and how can I know if there is ongoing AMI with shock or just this is shock signs?

[@ICUAdvantage]

12-lead is going to be your friend. Some ST elevation can occur as a result of decreased perfusion from the shock state.

[@stuartshiff7201]

Which videos of yours are absolute musts for a new-grad RN going straight to ICU? As in, what should I watch just before day 1? Thanks!

[@ICUAdvantage]

Hmmmm.. really good question. I will preface to say that watching these before you begin will be a good exposure to something that you don't quite fully grasp. It would also be very beneficial to rewatch after some time and you've had some direct experience with some of it. That said, I'd probably go with these playlists: ECG/EKG Interpretation, Ventilators, ICU drips, and then probably ABG Interpretation. If you are going CVICU, then Hemodynamics as well, although that is a good one for anyone a little bit later, along with the Shock series. Let me know what you think and best of luck on the new adventure!

[@tungtracy9052]

Like this a lot

[@ICUAdvantage]

Awesome! Thank you! I was really happy with how this one came out.

[@Deron8564]

16:23 . I think the kidneys make renin. Not sure if the adrenal gland does.

[@ICUAdvantage]

Yup 🤦

[@freak8510]

Nice explanation👍🏻👍🏻. Pls use a pointer coz its difficult to identify where is the new line is start. 😋

Thank you! The method that I do the writing and recording doesn't allow me to use a point. Its a bummer as I wish I had that available.

Hello ICU advantage, will you do anything from neuro?

Hey Ivan, I actually have a couple lessons coming soon in the pipeline that are neuro related topics. I do also have a video on the Glasgow Coma Scale already. Anything in particular you are hoping to see, or just the overall specialty in general?

Thanks! This one’s a keeper.

your video mentions that renin is produced from adrenal gland which is an error. It comes from kidney

Yes, it was a mistake on my part

Nice video but renin is produced in kidney and not adrenal gland and ADH does not cause reabsorption of sodium in kidney, only water

pls can you share the reference for you lecture.

[@ICUAdvantage]

I use many different reference sources along with my own knowledge over the years. I put these lessons together myself based on all of that.

[@davidmalpass5075]

Renin is released by the kidney (juxtaglomerular cells), not the adrenal gland

Correct. Wish I had a way to edit once uploaded.

[@Zizuthecreatorlamarwest]

Summary on what shock is: Shock is caused when oxygen is not getting to cells, leading to organ damage, and anaerobic metabolism, which causes lactic acid to build up, leading to acidosis, and prolonged shock can cause death.

[@ICUAdvantage]

Pretty spot on
