6 years later and I'm STILL learning from you! I always come back to this video to refresh my mind about anesthesia machines. Now I can teach my interns :) thanks Dr. Chavez.

I'm currently in school to be a CVT and have a sx exam on anesthesia machines and anesthetic drugs coming up, your video was SO helpful and really made it easier to understand. thank you so much!!

Everything suddenly makes sense now after watching this!! Amazing explanation

Hi Dr. Oscar Chavez! Just wanted to thank you so much for taking the time to do this. I am currently a 2nd year veterinary student starting my surgery and anesthesia courses. We will be doing our first spay/neuter surgery in 1 month and ahhhhh, I'm super excited but really trying to feel comfortable around the anesthesia machine. Thank you so much for this video! I took so many notes + it was SUPER helpful. Thank you!!! :-)

Your video is greatly appreciated! It sure does help me with midterm coming up and having to trace a molecule of oxygen through the anesthetic machine. Thank you!

This is ABSOLUTELY THE BEST anesthesia machine tutorial EVER!

i passed my anesthesia exam because of your video..thank you again..amazing presentation...

You could specialize in veterinary anesthesia as a RVT (Registered Veterinary Technician). The specializations for RVTs are under the VTS program, check out: VTS AVTA for more info.... and the best part is that becoming an RVT is much less expensive that becoming a vet, and almost all anesthesia in veterinary medicine is handled by the vet techs anyway.

Thank you for your help! I am a VT student at Ashworth College, and I can't wait to get started!

This was so helpful. I'm learning about Anesthetic machines in my textbook right now, but I couldn't picture it in my head. I can now! thank you so much.

very educational. It helped me so much on my anesthesia machine final exam.

I loved this video. Thank you so much for going explaining it very thoroughly. I' m a Vet Tech student and I found this to be extremely helpful. I now have a better understanding of how the machine works.

Thank you for putting this very educational video up!

This was honestly very helpful. Thank you.

this is amazing presenation!!!

Thanks Dr. Oscar Chavez!

Thank you for uploading this video, I'm eager to watch more!

Outstanding video! (I'm a CPhT/RPT in Florida (USA)... This is an outstanding, informative review. Wish it were a CE - Continuing Education module!!! Thank you!

This is very informative! Thank you Dr!

Thanks for this great lecture!

Great video! Thank you so much!

Thank you very much! This was very helpful.

!Great explanation. Thanks for sharing

it was a great presentation! Thank you

this was a huge help, thanks

Muito boa explicação. Obrigado pelo esclarecimento!!

Excellent description. Thanks a lot.

I FINALLY UNDERSTAND!!! THANK YOU!!!

You are amazing at this... Please share more with us

Bain is not a rebreathing circuit - that is a Universal F rebreathing circuit in the video

Great presentation I like it.

Great explaination!

Very Good Presentation, thanks for sharing.

Great video, thanks! Can you please give an example of both when negative or positive pressure might build up in the system, and how you would handle it. Thanks!

Dank you very much for this great video. I thank you soooooo much

that was soooo amazing thank you so much

Thank you, thank you, thank you!

Great informative video!

AMAZING!! THANK YOU!!!

@drochavez OHHHHHHHHHH. that is so good. Man. I've seen people turn the vaporizer on on KZfaq with the flowmeter ON, and with it full, and turning it up to like 4%, and you can bet I was not happy. Yes, sence the flowmeter was off, no flow will be carried through the vaporizer.

Thanks for posting this valuable video

This is such a helpful video thank you! I am just wondering, I know this is a re-breathing circuit, but I have heard some systems referred to as either 'in or out of circle' and 'opened or closed' systems.. does anybody know what type this system is?

Great videos, thank you very much. They were too good. If possible can you post some surgery related videos too.

@ngaingai Technically you are correct. A coaxial bain is a non-rebreathing circuit which is essentially a modified T-piece. I mispoke and referred to the rebreathing circuit in the video as a coaxial bain. It is just a coaxial circuit. Initially the bain was the first coaxial circuit modification made, then the rebreathing modification came later. Its hard for me to say "coaxial" without saying bain. That's what I get for trying to do it all in one continuous take! Good catch.

Satisfactory demosntration.

Its such a great demonstaration... Would help lot of medical school students like us... Thanks a lot sir..

Do you have any reference dates for how often the CO2 canister should be emptied? I mostly mean for both practise where the machine gets used pretty much daily and versus a place where it gets used randomly so the color changes back to white.

thank you for presentation

EXCELLENT!

thanks so much..

@ventilator98 This vaporizer was between services so it was virtually empty. Also, you may notice the flowmeter was turned off at the time I momentarily demonstrated how to turn the dial on the vaporizer, so there was no oxygen flow. It is very unlikely any gas left the vaporizer. We 'use' equipment all the time for instruction, so it is never a "waste". Nevertheless, thank you for your concern.

Your videos are very informative. I noticed that you have something tape to the very front of this anesthesia machine that you never mention, with a red top. I am very curious as to what it might be. I have watched this video several times, will continue to watch it, it has just about all sunk in. Thank you for all of the service you provide for us. I know that you work very hard, and none of this is easy. Thank you so much. Candelyn

I learned it E-tank for eentsy, and H for huge :)

Hi thanks for posting the video but I thought the bain coaxial was a non-breathing circuit as it functions the same as a T-piece just the tube delivering fresh gas an the patient breathing tube are coaxial?

Hi, how do you bypass the isoflurane to give only O2 to a patient through a F circuit and an O2 mask?

Online there is this thing called the VIRTUAL ANESTHESIA MACHINE. IT IS AWESOME. YOu can see the gases flowing the green O2, Blue Nitrous, Yellow air, and Pink Isoflurane. YOU SHOULD CHECK IT OUT.

Thanks for the help! I am transitioning - back - to small animal medicine after going from working in small animal practice for 10 years, then medical research for 20 years. In medical research I did a lot of different types of surgeries, helping investigators in many departments. My anesthetic machine was very simple. This video helped me become more familiar with the small animal machine. I feel one very important part was left our regarding the f/air canister. If they are placed on their side, the activated charcoal will settle and a small amount of dead space will be created. The incoming gas will follow the path of least resistance and come out of the canister unchanged. I have done a study on this and published this paper: Flushing Induction Chambers used for Rodent Anesthesia to Reduce Waste Anesthetic Gas Lab Animal Vol.40(#3) pg.76-83 March 2011 I was also wondering what amount of time do you give the Soda Lyme? What percentage of the Soda Lyme is considered critical/needs to be changed soon, during surgery? Thanks again for this great video! It’s very difficult to keep something so intimidating, simple and concise. You did a great job!!

great

And the flowmeter has to be at atleast 0.5 L/min to pick up the anesthetic. :)

Link?

whats the brand name of this anesthetic machine

I like it

I want to be a vet tech

I was thinking about becoming a veterinary anesthesia specialist but the cost of Veterinary School threw me off. Good heavens, the average cost is around $140,000-$150,000?!

You must not use nitrous because I saw your N20 flowmeter, and noticed you did not say A WORD about the nitrous.

Born to Right Tight. Made to left loose. :'(

hear me out

clin path and anesthesia quickly became my least favorite things :)

YOur videos are wonderful. I loooooooove anesthesia equipment. BUT YOU MADE ONE HUGE HUGE MISTAKE. You cannot CANNOt be turning on the vaporizer when you are not using the machine on an animal. THAT IS HORRIBLE you would do that. You're waisting anesthesia gases. I've seen a few people do that on KZfaq when demonstrating this. YOU MUST NOT DO THAt. Its a haz material.
