Thank you so much for the Videos Dr. Eric. In this fast paced world, where we have little time to relax & de-stress, You sacrifice your leisure time, educating others. I appreciate your noble cause & selfless efforts. Such an inspiration!
u r an awsome teacher sir........ i have learned a lot from ur valuable videos "ur the one in million" .thanks alot sir......... do uploading new videos there are millions of medical students eagerly waiting for ur videos....... Dr.Susheel from INDIA
Interesting... I am new to IV Therapy but I think a Phlebotomist Tech should learn this more since they are well versed with most of it. Great video on the theory of IV Therapy.
Hi Eric, LOVE ALL of your videos. Your contributions to those of us studying medicine are priceless. I did want to reiterate a question asked by trieu ho and Alestar Bronson: if you add an isotonic colloid solution to the intravascular space, I see no reason why water would want to redistribute itself, and even if it did, how would the osmolarity of the intracellular and interstitial space not go up (you have a loss of H20, but no change in solute count --> Osmol increases)?
This is so useful as I just did some study on renal medicine. Looking forward to part 2, 3 and 4. Thank you very much! I have enjoyed all your previous videos.
Rui Li How about nutritions. It plays very important role in treatment strategies espectially in chronic disease and in intensive care units. Hope he can make it.
Great lecture Dr. Strong. 17.25 you mention that the osmolarity of the colloid is identical to that of the body, so there is no change in osmolarity. If osmolarity of the colloid is the same as that of the body, how the infused fluid will enforce pulling force, as a result of oncotic pressure emerging supposedly due to osmotic gradient, on cells? Wouldn't the equilibrium of osmolarity be higher than normal following fluid shift from cells to extracellular space, which'd cause a decrease in initial rise in osmolarity in plasma following high-osmolar fluid and an increase in osmolarity in intracellular fluid following losing water to extracellular space, causing a new higher osmolarity equilibrium?
I have the same question as one of the viewers, trieu ho. Whats the mechanism by which isotonic colloids pull the water into intravascular space? technically it should be osmotically neutral when compared to the interstitial space, isn't it?
I'm little confused. As you said in the video osmotic pressure draws water from less osmotic areas, so techically if they have the same osmolarities, water won't move from one space to the others. And if the large molecules is a part of which create osmotic pressure, how isotonic colloid can pull water from interstitial space into intravascular space?
Is glucose a non penetrating solute? and is there a different unit for tonicity to distinguish it from osmolarity like how do you know that the solution is isotonic if what is given is the osmolarity of the solution?
Hello doctor strong , may I ask why in 17:42 , the picture of addition of isotonic colloid shows that the intracellular volume also decreased? If the colloid fluid is isotonic , why the intracellular fluid is pulled from intracellular to intravascular? Thank you
Hi, Dr Eric Strong, I am a pharmacist and a medical student from Australia, and I appreciate your videos very much, but can I please have the PDF version of ABG lectures as I really want to get a hand of it before my internship starts, thank you.
+Nelson Lam Thanks very much for your message, and I'm glad the videos have been helpful. Unfortunately, I've been working on a book on ABG interpretation, which will be based largely on the same info in the videos. I've been advised to hold off on providing any relevant printable materials on the topic. Once (and if), I ever get the thing published, I'll definitely let subscribers know about it.
thank you, I am looking forward to getting your book then, in that case can I have your PDF Ekg and pulmonary test lectures? I sent you an email not long ago and it is an optusnet.com.au email address, greatly appreciated if you can do that for me
Not even once in my entire years in med school have anyone explained IV fluids as clearly as you did doctor, thank you so much
Thank you so much for the Videos Dr. Eric. In this fast paced world, where we have little time to relax & de-stress, You sacrifice your leisure time, educating others. I appreciate your noble cause & selfless efforts. Such an inspiration!
Alestar Bronson Well said.
Do you that you are great doctor !!!
I have graduated from medical school since a year , and You are one of my favorite doctors ! Many thanks
God, thank you for hydration and healing and for all IVs. Thank you for medicine that helps us heal in the mighty name of Jesus. Amen 🙏
Whoever you are making these videos, It's official, I love you man! You're an education hero!
This is the first time I saw a demonstration of osmosis with a moving membrane. Very nice touch.
This is the best channel to clear your basics ans learn efficiently.

I always had trouble in understanding fluid distribution in med school. Thank you so much for this.. You made it very clear

I'm using these videos to help prepare for the MCAT.
awesome Lectures Dr Eric. Thank you very much
Great video. Thank you for making your content available to us!
I am addicted to your videos! Thank you
+Dominique Pordeus. Mas olha só quem eu encontro aqui! =D
+Diego Trigueiro Eu AMO esse canal kkkkkk
+Dominique Pordeus é realmente muito bom!
Thank you very much for these videos, you explain the concepts really well.

best explanation I have heard thou far. Good stuf
such a beautiful & simple explanation... just awesome sir :)
Great stuff Eric!

Was asking myself the same .. other ppl in comments did aswell, couldn't find an answer ^^
I have the same question as one of the viewers, trieu ho. Whats the mechanism by which isotonic colloids pull the water into intravascular space? technically it should be osmotically neutral when compared to the interstitial space, isn't it?
Amazing lecture thank you so much
Awesome video! Thank you
Great work Professor Eric!
hey, I saw the ikea hack on your other channel. great vid
Thank you so much for the Videos.
Now I know the difference between tonicity and osmolarity
I'm little confused. As you said in the video osmotic pressure draws water from less osmotic areas, so techically if they have the same osmolarities, water won't move from one space to the others. And if the large molecules is a part of which create osmotic pressure, how isotonic colloid can pull water from interstitial space into intravascular space?
For the last example, wouldn't the addition of isotonic colloid draw no fluid from either of the other two compartments?
great work doctor
Is glucose a non penetrating solute? and is there a different unit for tonicity to distinguish it from osmolarity like how do you know that the solution is isotonic if what is given is the osmolarity of the solution?
For compartments spontaneously create if astigmatism of cerebral palsy occurs.
Used electrolyte water dispersion for a limp pup, always know what you are doing
Could someone please re-explain tonicity vs osmolarity?
Also, is hypertonic fluid technically the same as colloid?
Hello doctor strong , may I ask why in 17:42 , the picture of addition of isotonic colloid shows that the intracellular volume also decreased? If the colloid fluid is isotonic , why the intracellular fluid is pulled from intracellular to intravascular? Thank you

Thank u sir 👍🏻
I watch this channel for the music
Hello Eric thank for the videos, it seems like this video is not working
+Piyush Sony Hmmm...it's currently working fine for me. Are other people having problems playing it?
I think its working fine now it just was taking a while to start up. thanks
Ok. Thanks for mentioning it though. Rarely there are weird problems with a video that requires them to need to be reuploaded.
thank

This explanation is waaay too circuitous for me. Tonicity is not that complicated.
