why dopamine and dobutamine are mg/KG/min ,
Dr Seheult, you are incredibly gifted and i love listening and learning. I am a nurse and you make the "why", which is how i learn, come alive. Thank you sir for your generosity in putting this out there for us
+Lisa Towe thank you! There are also free videos over at Medcram.com
Ditto
I am a nurse and listen to lost of your lectures. It has helped my learning so much! It is so appreciated!
Wished I had this medcram video when I was doing my critical care internship. I struggles to understand them. My preceptor was so knowledge but i just couldn't understand his explanations and felt so intimidated by his knowledge and everything else going on with our pts as well. Did slowly learned them and stuck it out. Stayed for 26 yrs and justight come.back to ICU as I've enjoined having to push myself learn more. Can't explain it. I'll be watching more of your videos for sure. Thanks for explaining it where it is easy to comprehend. This will be helpful to so many med students and nurses at bedside, especially in ICU. 👍
What an excellent explanation! Everyone should watch this!
As a pediatric ICU fellow, thanks for this. Nice review.
Your video is amazing! Thank you for posting. I'm new in the ICU and this video has been tremendously helpful.
Literally one of the best to the point mini lectures I’ve ever seen . Watching this bc I’m going to apply for CVICU RN bc I’m maxed out in my cards role currently. Looks like I’ll have plenty to learn and looks like a lot of fun. Thanks!!
Elizabeth Askander how are you liking the CVICU?
WOW! This explanation of Vasopressors are awesome. This really gives me the confidence that I needed to be a better ICU nurse. Thank you
Helping me be a better nurse and get ready for CRNA school. Thanks!
This is SO helpful!! I had to read a long wordy article to figure out all of these pressors.. great visual
Thank you for this! The other ICU page is so boring, this is straight to the point and illustrations help.
Great teaching never had anything exlpained so clearly
Good to hear, thank you!
This was great .! I left the ICU but went back because of COVID needs and this was a great review. These patients decline so fast .
I’m a LVN and i’m taking the prerequisites for the RN bridge program. My goal is to either be a ER or ICU nurse and then be a flight nurse. I’m glad I came across your channel. I’m watching them for the hell of it and I’m sure when I start the RN program, everything that I’m learing from your channel will come in handy.
your videos are so easy to follow, Thank you, more power, good health and God bless you!!!..
Thanks for your comment!
Best video on vasopressors
Easy to understand... Thank you for sharing 🙋
Elegantly done, nice job!
Thank you for this video. Keep it up.
Awesome video!!! Easy to follow thank you for sharing.
How I wished my critical care professor could've explained this in class when I needed it the most.
Omg one of the greatest videos and well explained in UA-cam 🥰🥰🥰
Thank you so much 😀
im a med student and I basically learn all the med materials from your channel. This episode totally helps me from memorizing the algorithm of advance cardiac life support. Thank you Sir!
Thank you for the comment. We have more videos available at our site MedCram.com.
Nicely done. Thank you!
thank you , I really needed it , good job 💗
Amazing explanation. Thank you so much. That was so easy to understand!!!!!!
You are truly awesome for this, thank you so much!!
Thanks for the video! This tied together a few loose ends in regard to pressors and got me thinking about indications for each. Big 'a-ha' moments for this RN who had worked in ED and with inotropics in end stage HF. Great job at explaining.
Thank you, great to hear!
Thanks a lot for sharing your talents
This video perfectly explains the medications that were mentioned in the video. It provides great insight on the various pressors and inotropes. Super helpful video. Many thanks for this video
Never let me down ! Thanks
That's just more than awesome!!!!!!! ❤️ ❤️ ❤️ ❤️ ❤️ ❤️ Extremely helpful!!!!
THANK YOU VERY MUCH I LEARN ALOT ❤️MUCH BLESSINGS FOR YOU AND YOUR FAMILY 🙏🏽
amazing clarification, thank you
Great educational video. Thanks and cheers from NYC!
Very greatful to your effort thank you
Great understanding 😃
This is THUPAH!!! DOOPAH!! Awesome sauce! Very useful quick refresher for the daily grind in my job. Inpatient Medicine NP here.
Thanks for the comment and enthusiasm!
loved this explanation, thanks
Thanks for explaining this!!!!
Thank you thank you this video delivered an explanation clearly, as promised.
Hi! May be possible to have a similar video regarding inotropes meds instead please? This one about vasopressors is very clear and perfect, it would be perfect having one about inotropes as well or even about the main differences between the 2 groups of drugs! Thanks a lot, I really love your videos!:)
this video is so helpful, thank you
Glad to hear it's helpful. Thank you for watching.
Great video. Thank you so much!
Great Video, Doctor,
Hi from Ghana.
Very useful and good information for medical student
Thank you sir...!!! Understand verywell i got very good idea about from this. I am from 🇱🇰
Thank you so much this is AWESOME
Thank you 🙏 so much for the explanation
Is there or can there be a lecture on warm versus cold shock? These are great videos and I feel like my understanding would be improved if there were a video about the two. Than you.
Very useful! 👍
Thanks so much for the detailed yet easy-to-comprehend explanation.
Great video! But what about “alpha2” receptors?
Thank you
Thank you ...it's amazing 👏
What about other class of durgs such as Flavonids (e.g. Daflon), How does it work?
Thanx
Where is the "next" video located at?
I am a ICU nurse reviewing for CRNA interviews and these are really helpful!!! :)))

Excellent! Thank you
Excelent Video!!
Thank you!
Superb 👏👏👏
Wow.. thank you
Amazing video!!
This is an great video for review of vasopressors & their mechanism of action. Question though... in my region of the country we administer all vasopressors weight-based, ie; mcg/kg/min. I my area of practice, I do encounter some pressors in mcg/min. That frustrates me, because I’m told by the sending nurse “They’re maxed out on Levo...” I get there and find them on 5 mcg/min of Levo and think to myself, “That’s no where near max dose...”
Why is it that weight-based pharmacotherapy isn’t universal? Thank you so much for the FOAM.
Very good 👍
Finally, I understand the difference between the vasopressors. I didn't understand how a alpha pressor could work when a Beta 2 was also being stimulated. I had no idea they were stimulating at different strengths... ugh... NOW I KNOW!
4 years ago I was diagnosed of HUNTINGTON DISEASE and I have tried all I can to get cured but all to no avail, until i saw a post in a health forum about a herbalist man who prepare herbal medication to cure all kind of diseases including HUNTINGTON DISEASE , at first i doubted if it was real but decided to give it a try, when i contact this herbalist via his email and he prepared an HUNTINGTON DISEASE herbal cure and sent it to me via UPS delivery company service,when i received this herbal cure, he gave me step by directions on how to apply it, when i applied it as instructed, i was totally cured of this deadly disease within 1 months of usage, I am now free from HUNTINGTON DISEASE ,all thanks to Dr Joshua Ighalo. you can also reach this great herbal doctor for help . He can help get rid of yours permanently.. Also specialize in treating all kinds of illness, HERPES VIRUS, HEPATITIS B, CANCER, BRAIN DISEASE, INFERTILITY, DIABETES AND MORE. ....
Bem legal hein :)Medcram - Medical Lectures Explained Clearly
Well done
you might want to switch to µg/kg/min as unit of dosing *all* continuous applied vasopressors instead of µg/min - because giving 20µg/min is different if you have a 40kg versus a 150kg patient. With µg/kg/min you can compare the need of pressor support between patients (and say: "gosh, that´s high, I need to consider other causes/actions").
I do see the problem that this is an institutional thing - if everyone is using ml/h (with various concentrations of pressors) and you´re the only one to use µg/gk/min (or gamma, as we colloquially call it) that might lead to problems in understanding...
Thankya
Depending on the institution or facility, epi, norepi and phenylephrine can all be weight based dosing.
This is amazing. Thank you for sharing this!!
I am not studying to become a doctor but I love watching your vids. You make the subject matter very interesting to non medical school audience and it surly takes talent to do that.
Is it possible for a CHF patient to be on both Dopamine and dopedimine simultaneously?
Why do we usually start with levophed ?

Nice
Thumbs up Remember......there is always something undiscovered.......That's what my wife has.......good Job , continue on DOCTOR's . Doctor is a big deal , because that's what you are or could be. Love you guys.....Please continue...I am depending on it......
no benefit for low dose dopamine? That's news to me, thank you, I'll look into it!
Would I have permission to recreate your table for a CVICU nurse education program I am putting together for my unit? With an appropriate citation of course!
Hi
Want to ask if the patient is allergic to phenylephrine , dose that mean he is allergic to norepinephrine or epinephrine?
Thank you
Subscribed
Big like
Because beta blockers typically block B2 receptors, does that mean they have a vasoconstricting effect as well?
No it's the reverse... they have vasodilation effect.
VM/VMA ratio high 4. How do I get dopamine transform into norepinephrine?
I thought levophed didn’t have much in the way of chronotropic stimulation? B1 is made out to seem from your initial explanation that B1 includes HR inherently.
Your video's is awesome
So, in the Beta-2 column, the dots actually mean it acts as a vasodilator rather than a vasoconstrictor?
Yes.
Why is Isoproterenol classified as Vasoconstrictor if it has effect on Beta 1 and 2 only?
Why is Epinephrine given in EpiPen and isn't Alpha-1, Beta-1 are doing the opposite? Thank you so much for explaining.
I believe it's given for the vasodilatory effect on the lungs/trachea in that situation, not for the vasoconstrictive properties.
Are you asking if stimulating alpha 1 and beta 1 is counterproductive?
Should norepinephrine be used for autonomic disorder ?
What drawing app are you using?
Great video! Thank you so much!!! Wish someone would explain Alpha-2 to me. Had a question about Norepinephrine.
Amiodarone... Where does this fit into things, please ?
Amiodarone is an antiarrhythmic drug, and is commonly used during certain cardiac dysrhythmias like persistent ventricular tachycardia, with and without pulses, and ventricular fibrillation. I believe amiodarone has a blocking effect on the calcium, potassium, and sodium channels in the (lower?) heart, so it works to slow down the ventricles..... ACLS has amiodarone as a push dose for pulses v tach and v fib, and has a drip dose rate for vtach with pulses..... As far as I know it doesn't have any effects on alpha receptors... that's all I know as a paramedic student lol!! Hope that helps :)
What about alpha 2 receptors?
What does Alpha 2 do?
thank you so much!!
What about Milrinone ?
