Full tour of the anesthesia machine

The anesthesia machine is the centerpiece of all the anesthesia equipment, and yet it doesn't actually get much attention. In this video, I show you some of the key functionality of the machine and explain how it facilitates safe patient care.

Thanks Doc, If I had 25 years remaining, I'd become an Anesthesiologist. It's the most fascinating medical field; a lot of the other fields are carpentry. At 84 I'm running out of time so I'll stick with learning as much as I can. This has served me well in that I have caught doctors either lying or being ill informed.

I have a new found respect for anesthesiologists. Thank you for your videos. Up to watching your videos I thought that your only job was to put us to sleep and wake us up. Thank you for opening my eyes. Puppy hugs to your fur baby..

[@mhenderson9311]

Interesting video! So it's not just all about the drugs and the chemicals. Anesthesiologists also need to be concerned about gas pressures and volumes. So much concern goes into planning these surgeries. Thank you for sharing!

Ive learned SO much about anesthesia from your videos that I was able to name everything in the operating room to the anesthesiologist during a recent procedure. He and staff got a kick out of it and it really put me much more at ease knowing what was happening. Thank you very much for your content.

Well done video. easy to understand. Im not a MD, Medical Simulation Tech. We do a lot of training for the Anes. residents

[@sandyseibelhager7131]

Very cool. Way more fancy than the very old system I used in the veterinary clinic. Ours had a knob for flow rate, a bag and co2 absorber. No monitoring or anything else. It didn’t even get plugged in(totally manual). No power, no problem. I believe the machine was from the late 60s or early 70s. Reworked to run isoflurane

[@RobinHood70]

Story time: Back in 2010, I had an anaesthesiologist (possibly the resident) who forgot that all-important "Gas Delivery" checkbox. I got the anaesthetic, but no airflow apart from that. I tried to indicate that there was a problem, and at first, they took the mask off and set it near enough that I was still getting the anaesthetic, probably thinking that I just didn't like breathing through a mask. They never actually checked the airflow, though. Later, they put the mask back on without so much as a "by your leave". I tried again to indicate that there was a problem but the two nurses standing near me were both blabbing away and I was so out of it that I couldn't get their attention. My last conscious thought was that I knew I was hooked up to an O2 monitor, so they were bound to notice that dropping at some point and fix the problem. (Yay for anxiolitics making that a very calm thought.) They must have clued in at some point cuz I was distantly aware of air suddenly starting to flow before I lost consciousness completely. I never followed up, but I wouldn't be surprised if I had a spot in the next M&M.

Thank you!

[@christopherleubner6633]

Used to repair the laser anesthesia gas monitoring units. They had either argon ion lasers or helium neon lasers. The argon laser ones had a low powered laser in them that would cause the various gases to glow at raman frequencies. The HeNe units were similar. The oxygen was measured using a servomex magnetic oxygen sensor. The newer ones like yours use a near infrared spectral absorption sensor as those cover a lot of gas choices as well as monitor the CO2. The sensor unit is very small compared to the laser based ones. ❤

I’m having a hysterectomy a week from Thursday. This isn’t my first surgery as I’ve had several. It is however the first one where I’ve had an organ removed. While I’m no stranger to anesthesia, it actually helps calm my nerves a bit knowing what all goes into keeping us alive when we’re so close to death.

[@molu10591]

You should get the Et Control upgrade option for your Aisys CS2, it will make your like so much easier. Also, its better to monitor FiCO2 rather than EtCO2 to find if the absorbent has exhausted. EtCO2 can take a while to build up to be noticeable or triggers an alarm.

[@JohansenHosein]

Hi I love this

[@zachmcpherson97]

Love your content! Do you work with any CRNAs? Would love to see an interview with one and their role at your practice! Also, maybe a scrub hat tour with links? You have some awesome ones

[@sarahvlach2767]

I ditto this - I'm considering becoming a CRNA and would love to see a their perspective.

[@sarahvlach2767]

Dr Max, thank you for your videos. I'm considering becoming a CRNA because of your calm demeanor, nerdy details in your videos and truly seeing how possible it is to learn anesthesia. However, CRNAs lean anesthesia in 3 years during their DNP days, they perform anesthesia the exact same way an anesthesiologists does. Could you include content with a CRNA? I'd like to explore CRNAs further. I almost quit my hopes of becoming a CRNA after leaning they insert central lines snd arterial lines. Have you posted a video about this? I also appreciated your cideo about blood product transfusions. I'm shadowing a CRNA next month and because of you, I will actually have something of depth to talk about and explore further with the CRNA. Many thanks for sharing your knowledge. 🎉

[@DamonJohnCollins]

As someone who budgets/orders/deploys this equipment, I'd love to know more about the accessories that are likely (or possible) for different specialties to be sure we include everything needed. My last project, we didn't know we needed to purchase the vaporizers and we, in fact, needed 2 types for every machine. Thanks Max!

If you read this.... Coincidentially I'm currently busy on a detailed 3D model of a mechanical bellow driven ventilator (from scratch). not for any professional and/or medical purposes, but purely out of my own interest as a portfolio project. this video surely will help better understand the inner workings.

[@rachelreid8621]

Hi Dr.Feinstein! I admire your job I really do. I'm wondering if you have ever experienced a malfunction with the machine? If you did what would you do in a case like that and what would rhat mean for the patient?

That's the most important machine in the room! :) Would be amazing to see the central storage tank/area for O2/air/NO2 if you can find them/or if it's allowed.

I volunteer in a children’s hospital and sometimes just before they are anaesthetised they sometimes get the wiggles and start rolling and moving. So I was wondering what this phenomenon is called and if you could please do a video on it. Also this was a great and interesting video.

Hey Max is there any way the next time I have surgery you can put me under? Last time I had anesthesia they had to put me under twice

[@joshbritton]

In terms of making your videos, do you write a script first and then get all of the shots you need? Or a bit of both? Or solely shots first based on what you know/want to say and then write a script after?

[@MaxFeinsteinMD]

I always make an outline, but I don't write a full script!

After my general anesthesia I had a large swollen gland on the right side of my neck that lasted a couple weeks and eventually went away. Was this due to intubation?

[@ncooper8438]

I saw the title and watched the video but there was no description of the anaesthetic gasses used or how they were delivered. This video is mainly about ventilation.

[@MaxFeinsteinMD]

Correct, this video is about the machine, not the medications administered

[@jeromedavis8575]

[@bradzeigler]

@maxfeinsteinmd I’m curious, as a Pediatric Anesthesiologist, would you be interested in doing a video breaking down how the 2018 Thai Cave Rescue team used a cave diving anesthesiologist to sedate the boys using Ketamine and other drugs to facilitate a safe rescue? It’s an amazing story but I’d love to hear more on the medical side of how they pulled it off.

[@MaxFeinsteinMD]

Yes!!! I watched one of the documentaries and it blew my mind. One of these days I will make a video about that. Truly incredible.

[@Andrei26888]

Is it possible to have general anesthesia without curers? Because I suffer from sleep paralysis and going into surgery knowing that my body is so paralyzed which is similar to sleep paralysis.

[@danieldaniel4375]

I have a question. I had a surgery awhile ago. I have several problems that I told the staff about. I asked them to make a note and let everyone that would be there know my simple directives stemming from my issues. I was reassured that my request would be fulfilled and that the messages were taken and would be shared. My request were ignored and when I got the records from my surgery there were no notes about my issues or request. Is there other records that staff share? Or was I just lied to about them being accommodating so that they could get me into the room?

Do surgeons pick the anesthesiologist, or are anesthesiologists assigned arbitrarily to surgeons

[@robertobryk4989]

What's the typical fraction of gas that's recirculated (i.e. the ratio between respiratory_rate*tidal_volume and gas inflow)? I'm surprised that recirculation is worth it, given that (a) the temperature/humidity/... could be ensured with heaters/evaporators/... (b) it adds a scrubber breakthrough failure mode that has to be distinguished from problems that have their cause inside the patient. Am I very wrong in one of these assumptions, am I missing something, or is this just a question of somewhat different weighing of tradeoffs?

[@balzoemg8415]

I recently had a colonoscopy & endoscopy. They told me they were using propofol, but when I looked at my paperwork, they added fentanyl with propofol. Do you know why this could be?

[@MaxFeinsteinMD]

For these types of procedures, propofol is very commonly the main medication for the anesthetic and a bit of fentanyl is added on top of that for pain control (propofol doesn’t help with pain).

Why is intubation required on some surgeries and not others?

[@Joel-zc3xl]

Intubation is required for any surgical procedure that requires the patient put under GENERAL ANESTHESIA which one part of it is muscle relaxation and cessation of breathing. So an endotracheal tube will be inserted and the machine will breathe for the patient for the duration of the general anesthesia. The other is REGIONAL ANESTHESIA which only certain part of the body is anesthetized through various methods such as nerve block but no relaxation of breathing muscle. Thus it will not be necessary to intubate the patient. In short Intubation is only required when the machine needs to breathe for the patient.
