You saved my life when I was I. Nursing school! I’ve been a nurse almost 4 years now and I still come back to you for brush up ! Thank you 🤗

Wow, such an old video but you literally just simplified BUN and Creatinine for me better than any online source. Thank you for all your videos, will definitely be visiting more often since im in my second semester of nursing school

So i watched many of yur videos on youtube and because of this it was one of the main reason i passed my nclex on the first try with 75 questions oh yea!

You have helped me through Nursing school more than you will ever know. I take NCLEX in 2 months, not scared but excited. Thank you so very much for all your help. My whole class loves your work.

For everyone watching these amazing videos, please understand these lab values. I understand there are lots of lab value questions in the NCLEX. Thanks alot Mike!! I appreciate your efforts to make students (like myself) pass exams.

Thank you so much. I feel like my professor was useless in discussing ALL aspects of our renal unit, and this has helped so much.

I love this! We were doing this the other day in class. My teacher did not make much sense. I saw your video and it makes much more sense! Thanks!

This is a very good explanation of BUN and creatine. It solidifies it in my brain. Thanks Mike!!!!!!

Oh my goodness, thank you thank you for simplifying things and talking slow and being so animated. Thank you

I love to see the transformation of these OG videos.

Tons of nurse teachers cannot teach it because they don't understand it. But this guy here actually knows what the Renal system is. Wow, all I can say is, you are absolutely outstanding, you should teach the entire country, maybe there could be more nurses out there that actually know what they are doing. Thank you Michael, you are awesome!!!

Your videos help me!! THANKS! They make Nursing School less stressful!

I want to hate you something about makes me want to hate you but your explanations are actually really good ...bless and thank you from all us nursing students that don't want to give you the props you deserve

Sir I want to thank you for your teachings, your videos are quite helpful even in India

thank you so much Michael....just started back to floor nursing after 20 years....I am a senior citizen LOLSo much to review...glad I found you.RU-vid nursing school...who would have thought it in my schooldaze?Bravo and thankyou

I'm so glad I found you! Keep it up!

About to take NCLEX in 2 months. Watching your videos. Will come and update after I pass.

I have normal hydration, normal Urea and low creatine causing 40:1 BUN, I have been diagnosed with Thalassemia, as well as 4 genetic mutations that are also troublesome. The BUN creatine ratio was the first clue! It was overlooked as dehydration for several years.

Thank you for your help in nursing school five years ago!!!

Thanks so much! I love being taught tips and tricks to remember things like you taught in the video!

I'm 64 years old. Started supplementing Creatine HCL, L-arginine and L-Citrulline about 3 - 4 months ago and am VERY pleased with the results as well as my wife being pleased also. BUT recent lab bloodwork shows following: BUN 1.54 and GFR 48 Putting me at 3rd stage kidney failure by standard chart. Should I be concerned?

You explain this very well. Thank

You explained that well way better than my PCP. I think my doc is confused on this. 6 months ago both creatinine, bun , and ratio was all high. I had adema bad. He said if both are high it's just dehydration. I got fluids, went on a renal diet for a month retested and they all came down which is great. But 6 months later and I'm having i.c symptoms, it hurts to pee, and my bun is high not extreme just 21. My ratio is considered normal at 22 but that's high end of normal, my creatinine is low and my gfr is 100 all good things except the slight elevation in bun however I'm swelling again and the bladder urethra issues

Hey, thanks so much for your time, it truly is much appreciated. God Bless!

hi thank you for the analogy with Buns and two kidneys and two values. Very helpful

That was amazing! Thank you so much for breaking it down

My BUN levels were 21 but my creatinines were well below range so I’m good. Thank you for the video I was already looking for kidney donors 😅

Ty so much for putting videos . I learned a lot from u . Luckily I found u

When you get into it more in depth you learn about hyper- filteration also. This may not be taught at a nursing level but out of a hope that someday it will be and that diagnostics for rare and hematological diseases will become more widely practced I would like to add hyper filtration as something important to know ! Especially for those who suffer from rare hematological diseases. A low creatine, and high ratio above 20:1 indicate pre kidney injury which Is often over looked because it is less common, and not included in lower or intermediate level medical training. (Which is due to statistics, politics, Money, and the policies governing curriculum and the financial feasibility of certain diagnostics which is another subject). So, back to hyper filteration ; Yes, it could mean dehydration or heart failure but it is also a sign often seen in hematological disorders like sickle cell anemia or other sickling diseases that affects blood flow, and due to the blood flow being restricted the kidney re filters trying to compensate and in this process some things only filter once and that number maintains at that level regardless of the number of the number of subsequent filterations. and other components change each time it's filtered through. The increase in the ratio should be a flag to look at The blood flow pre- kidney and consider what could be restricting it.

Thank you for this! Will you be re-recorded with your cool graphics?

I love your videos man,I loved the "wat was the last one again " part. Thanks for your videos

respected sir thank you ....

Hey man love your vids, I'm a big fan. One small detail in this one that I caught that might have confused a few people: at ~3:43, you mentioned BUN should be 3x Creat and gave the example that a Creat of 3 should have a BUN of 30. This makes for a BUN:Creat ratio of 10:1, not 3:1. The reference ranges I was always taught: BUN ranges 5 to 15 and Creatinine is .5 to 1.5. I know everyone has a slightly different reference range but for me, it was so much easier to memorize considering one was 10x the other.

Accept when there is a problem with low flow to kindney ! The ratio becomes greater. I think you said it backwards because if they both risewouldn't that be dehydration because if one is rising and the other is staying the same that means it's been filtered too many times, because generally speaking the Christian mostly is only filtered once, correct? So the other is building up bigger and bigger because there is a lack of flow to the kidney and therefore it keeps trying to recirculate?

Are you saying that high BUN and normal creatinine is a sign of dehydration or a low BUN and normal cratinine? I was confused the burning your BUN mnemonic.

Hi Michael, I have a relative who is a 55 year old male, he just found out that his SCr is really high, now 1.58, calculated CrCl with 56, eGFR 49 (non AA patient).... however the not a lot of the common systems CKD are present, no anemia, normal urination, potassium on the high end, but still within range. No DM, slightly elevated BP. Do you know what could be possible reason for this strange lab findings? :| Thank you for all your wonderful videos and hard work! I am a 2nd year pharmacy student, but without much clinical work at this point. I really can't help explaining what's going on...

my 3 quarter teacher was great

Hi Michael---love your videos. We are having a NSWS (Nursing Students of Washington State) Convention in April and would love to include something that will help get the word out about your services to our members!

Thanks for explaining that very well!👍🏽

Where can I get those lab values to be put on a card behind your ID picture?

I'm beginning to appreciate your videos the more I watch them. I do have one suggestion though, if you don't mind. You do a lot of "continuing" in the next video, which is fine but, I'm having to click on 3 or 4 videos to find the one that's the continuation of the one I just watched...in a nutshell, start labeling your videos Part 1, Part 2....etc.

Thanks Michael.

Does ekg rhythm monitor have blood pressure and pulse? Thank you, mr.Michael.

What do you mean by kidney involvment?

I have a question It means if I have high BUN nothing else is an indication of deshydration because I am worry

Love these videos and his explanations, it kills me every time he says "pee pee" 😂

Hey mike you cannot have the little lab card on Nclex so do you have a easy way to remember the values

Thank you for this

Old but gold

Lab values are calculated different for people of color, including native Americans, Latinos, Blacks, and etc. I never heard this guy mention that, A 30 year Nephrologist M.D. told me that.

hey, so if a Pt has a Urea of 9.4mmol/L and Creatinine 0.25mmol/L (these are the only lab values I can obtain), what would the Estimated Glomerular filtration rate be?

Thank you! So helpful!

My bun is 21 and my creatinine and bun ratio is at 24 is this bad ?creatinine is at normal range

Great video, but the title should be Creatinine, not Creatine :D

Great video

My BUN was also exactly 20 😅 is that okay or should I be concerned? I scheduled a renal ultrasound just in case

I wish my teachers would teach like this instead of just reading off PowerPoints 😑

thanks man...you ar doing a great job. let me ask you do you have anything for MB?

How did creatine urea get off a kidney transplant patient?

Thanks for getting me through nursing school! lol

Your video sounds like someone just poured milk on some rice crispies

Interesting topic

Hi Michael, i just need your help please? I got my blood test results back and the doctor said everything is normal in my kidneys but on the test next to Creatinine there is a number and it says LOW but Urea and Albumin are in the normal range. Should i be concerned?

Love all the videos.

Thank you so much your videos are so helpful :)

My BUN levels came back 6 & my creatinine was 0.87... Could my BUN be low because I'm vegan? Im a lil concerned. Thank you for any input

im low in potassium does that mean dehydration?? my bun is 28.50 mg/dl urea is 60.99 mg/dl

this is hilariously perfect, thank you !

What if your BUN and Creatinine are perfectly normal but have a GFR of 87, what doescthat mean.

What is the name of the little pocket chart? How could I get one?

my Buddy.................thanks

Very helpful vid mike!

Great video.

Awww.... you should update this

My bun/creat is high 29.00, and not normal, I also have a pacemaker implanted permanently to monitor the afib, most kidney tests are ok, but I also have bubbly foamy urine coming out

woow woow ur amazing thank u alot 🙏👏👏👏👏👏👏👏👏

Love it thanks

thanks love the video would like to get more pharmacological and I'm in south afrika

damn bro that was a great explanation, thank you

thanks sooo much!

What if there’s only a significant elevation of creatinine level?

Hey buddy, this was great. I appreciate the explanation so much. I looked this up to understand why the creatinine:BUN ratio increases in congestive heart failure......that said, you should correct your title (creatinine, not creatine). Although I do think gym rats will stumble upon this video and give you more views. :) :) :) :) :) :) :) :) :)

Me watching this video 9 years later omg

Hello sir what does it means when urea nitrogen and creatinine ratio low ?

My Creatinine is 0.56 is low Is that good or bad

Super!

What if its not high but its low

I have questions

Awesome

Renal part 2

I see your hands, I'm gonna put a ring on it.
