If you want to understand concepts, this would be the place.
Are we treating hypotension appropriately?
This gives a brief review about physiology of hypotension, identifying the cause of hypotension and making appropriate pharmacological choices for treating hypotension.
This video is only for educational purposes, please use your clinical judgment when treating patients with hypotension.

Low Flow Anaesthesia 1
Переглядів 2,4 тис.Рік тому
This is the first of 3 part video about low flow anaesthesia. In this part we understand what low flow anaesthesia is? And try to understand the benefits of practicing low flow anaesthesia to the patient as well as the planet. Part 2- would be about understanding how low flow anaesthesia works Part 3 - about the actual conduct of low flow anaesthesia.

Simulating feel of structures during central neuraxial blockade practical tips for beginners.
Переглядів 1342 роки тому
How confident are you in identifying the feel of the structures the needle passes through when performing central neuraxial blocks. This tutorial is an attempt to help new trainees/ beginners to get the feel of structures the needle passes through. So that they can perform these procedures more confidently. If you have any questions, please do leave them in the comments.

Problems you might face while using jet/ Venturi nebulisers, reasons, and how to overcome.
Переглядів 542 роки тому
Learning objective- to understand why you might face some problems and being able to understand why these happen and how to overcome them. To understand limitations of these devices.
Basic principles behind functioning of jet nebulisers or Venturi nebulisers.

Learning objective is to understand how exactly a Venturi nebuliser works.
Functional analysis of a Hudson’s face mask and comparing it with Venturi masks.
Переглядів 1902 роки тому
Learning objective. 1. Understand the functioning of Hudson’s mask. Relation between flow and rebreathing. 2. Understand why Hudson’s mask is classified as a variable performance device. 3. Understand why a Venturi mask is classified as a fixed performance device. 4. Would classifying them as high and low flow devices makes more sense.

Sir keeping making videos,, this level of high quality content is jot yet on youtube
Well explained 🔥
explained the concept very well
After multiple (failed) attempts to understand Venturi mask working principles, God was on my side today that I was able to find your video. Thank you for the clear explanation, will be forever thankful :)
Thanks. Glad you found it useful.
hi sir..I have a doubt. As the flow increases, pressure drop increases and upward force will increase. But pressure is directly proportional to force. so as we are increasing the flow, pressure is decreasing. since pressure is decreasing, force should also decrease na?
No the pressure drop doesn’t increase. That’s where the taper in the flow tube comes into play. Lower part of the flow meter space between bobbin and wall of flowmeter is small. So the five flow causes pressure drop which will counter the effect of gravity. But as flow increase bobbin moves up, the space between bobbin and flow meter increases. So the higher flow still generates the same pressure drop just enough to counter gravity. That’s why the principle on which flowmeter works is called a “variable orifice fixed pressure drop principle”
Sir..this music is disturbing..please cancel it.
Thanks for the feedback. These were among the earlier videos. In recent ones have either omitted the music or toned it down significantly.
What is the role of spring s2?
Hi will try to explain. In old regulators direct acting ones, force of spring s1 and cylinder pressure are the only forces which keeps the valve allowing gas to flow from cylinder to regulator open. SpringS1 used to be adjustable in nature. In a situation where spring S1 was left untightened and flow meter is left open, the gas from cylinder would flow through the regulator in an uncontrolled manner, with no control over the extent of reduction in pressure. In such situation, spring S2 would keep the valve shut preventing gas from flowing from cylinder to regulator. Modern pressure regulators are indirect acting, that is force of spring S1 will oppose entry of gas from cylinder to regulator. And the force is not variable but is fixed. So the newer indirect acting ones do not need a spring S2 at all and it is only of historical significance.
In fact, the music makes the video really interesting. I'd be bored to watch instead. Thanks for the music.
When you will release part 1and 2
Sorry some technical problems, finding it difficult to prepare in doodly. Might have to be done in power point.
Thank you so much sir..concept is very clear😊…kindly come up with more such videos sir..Thank you once again
Thanks. If you have any particular topic in mind, please do message will try to make video on that.
Very nice explanation of a difficult concept, Dr Sudeep! Thank you very much..
Excellent presentation. U have very good hold on subject.
By removing background music, you reduced the distraction.. 👌👌👌👌
Well explained, sir!
Excellent session, Sudeep! Concepts are explained in a crystal clear manner, thank you! I learnt a lot of new stuff..
The music is a distraction. Though the presentation is educational and thorough, it is difficult to hear your points with the music in the background
Thanks. That was in the early days. Subsequent ones have omitted the music.
Very confusing video
Don't be putting music in your videos
Thanks noted. Have avoided adding music in the newer ones.
Superlike
Great going , very succinct as always
In order to limit the duration of video have included only one scenario of changing respiratory rate and I:E ratio. You can please feel free to change the scenarios for all the parameters on similar lines. And do the math yourself.
👌👌
Very nice presentation, Sudeep! Please continue making more such videos explaining basic concepts with clarity. Thank you!
Excellent video Dr Sudeep. Very useful for the anesthesia students.
Well explained sir!
Will be deleting this video due to possible legal/ copyright issues with respect to using hospital logo. Will be uploading a corrected one shortly.
Simple and elegant explanation, Sudeep! Please keep making more such tutorials..
