I never understood waveforms. Your explanation is very good. You are giving us explanation for free mainwhile we paid a lot of money and spent times after times in school and they never teach us. Thank you so much.
Quick question, do you have audio versions of your videos on spotify? I'd love to listen to em on my way to and from work. Been following you since 2018.. your videos helped me so much during my clinicals in my student days 🙏
Hey there Coach, thank you so much for making this video.☺️ I am struggling with rapid sequence Intubation, particularly assisting the doctor. I freeze and do not know what to do. Can you please make a video with step by step instructions from the time we walk into a code to placing the patient on the ventilator? 🙏
another very helpful video. Thanks. Have you ever thought about doing a video with how to read the chest XR and chest CT? that would be extremely helpful especially now you have that screen you can show lots of examples of xray and CT images. Thanks again. looking for that video from you
Hello Coach, first and foremost I absolutely love your videos. I have a question that might have been answered but I didn't see it but how do you decrease inspiratory time on PS?
At the beginning of the video you said square is volume control and that decelerating is volume control unless accompanied by a square then its pressure but at the end of the video you said square and decorating are both pressure????
General question: Is flow continually going? And is it always at a constant speed/velocity? Or does it speed up/slow down according to volume delivered/pressure target reached?
You said that peep can be used in asthma patients, but there are many sources that tell us not to use peep because of the airways in asthma patients that are steadily narrowed, so what is correct in your opinion now
@9:30 How does decreasing RR increases E time ? If insp ratio is 1:2 on a resp rate of 20 , then it should be 2 sec for insp and 4 sec for expiration... On RR of 10
I think you answered your question, because you are exactly right. A 1:2 on a rate of 10 would be 2 sec inspiration and 4 sec expiration. At a rate of 20, a 1:2 would be a 1 sec insp time with a 2 sec expiratory time. Decreasing the rate increases E time by increasing total cycle time. Rate of 20 has 3 sec TCT, while a rate of 10 has 6 sec TCT. Does that make sense? Thanks for watching and commenting with your question.
Hi teacher.. A quick clarification please.. by air trapping do you mean autopeep generation??? And if that is the case how come increasing PEEP will help trouble shooting... Esp if I have a kid with asthma on vent where zero peep is the strategy I believe... Love from Pakistan for teaching us so good
Hi Faisal! Yes, air trapping leads to auto-peep. Increasing PEEP basically stents open distal airways, much like purse lip breathing, and allows for greater alveoli emptying. Thanks for watching and commenting.
I got lost a little coach. I thought the volume control is square waveform like you were saying in the beginning. How come when the first practice questions is square, and its a pressure control Can you clarify for me.
Hey joe, What if the air Gap in inspiratory wave, i mean the inspiratory wave doesn’t reach to base line and start the expiratory? Sometimes there are like couplet wave in inspiratiry flow curve. What does it mean? Thanks four your help.
Hello Amr! If the inspiratory flow pattern doesn't return to baseline, specifically in pressure control, then it indicates that a full alveolar tidal volume wasn't delivered. I would have to see the couplet pattern you're referring to. Feel free to send me an email to respiratorycoach@gmail.com. I'll take a look at it. Thanks for watching and asking your question.
VC has a square flow waveform. PC has a square pressure waveform. That's typically a point of confusion for anyone learning mechanical ventilation waveforms. Hope that helps. Thanks for watching and commenting.
Does the square shape always refer to the PCV ?, because at the beginning of the passage you said that it refers to VCV?Or is there an exception? I used to think that the square shape indicates CMV whether it is PCV or is VCV. Please answer my question, my exam is in two days and I messed up? .
I think it’s just a by mistake that he tells the square waveform a VC if you recognise at the end that he said again the square waveform are always PC and you can search in the internet about this information 👍
I'm sorry, I'm a bit confused, in the first video, I thought square waveform was VC, and if it descends w/a a square is PC but in this video the square is PC
so wait. he said pressure control was always decelerating and then when the squares came up he said PC is always square. i thought they were always decelerating. IM LOST.
Great question! In regards to PC, the flow is always decelerating. Hence, the flow waveform will appear decelerating, but the pressure is set, so the pressure waveform is square. Pressure waveform vs flow waveform. Does that make sense?
RN from Australia here. Your problem is the difference between pressure waveform and flow waveforms. square waveform (flow) = volume control Decelerating waveform (flow) = pressure control (always) or volume control (sometimes) In the MCQs the Square waveform isn’t a flow waveform but a pressure waveform Square waveform (pressure) = pressure control Please correct me if I’m wrong
thank you so much for the effort you put for us and teaching us, you've explained all these topics better than our professors, you saved us.
I'm here for you! Stay focused and enjoy your journey to RRT! Thanks for watching and kindly commenting!

Thank you, Madina! Doesn't seem fair, but the truth is you needed the confusion from the "paid for classroom" for me to bring clarity to. GO BE GREAT!
Hi Joe! These are great and I am excited for the next ones. This is the first time that I got all the questions right before you broke them down!
Awesome, Gie! Thanks for watching and commenting. Breakdown of the volume waveform coming this week!
This guys explain well better than my prof.
Thanks a lot sir

You re awesome 👌, please put out more content
Hello Coach, first and foremost I absolutely love your videos. I have a question that might have been answered but I didn't see it but how do you decrease inspiratory time on PS?
Insp time during pressure supported breaths is controlled by the patient. The only way to manipulate this is to adjust the expiratory sensitivity.
Good job. 👍🏽
At the beginning of the video you said square is volume control and that decelerating is volume control unless accompanied by a square then its pressure but at the end of the video you said square and decorating are both pressure????
Same
yes but that’s because you are on flow waveform.
Square is VC, PC is decelerating when on Flow waveform. When on pressure waveform, PC is square
General question: Is flow continually going? And is it always at a constant speed/velocity? Or does it speed up/slow down according to volume delivered/pressure target reached?

I got lost about the square wf. On the first part it represents VC, how come on the exercise it represents PC?
VC has a square flow waveform. PC has a square pressure waveform. That's typically a point of confusion for anyone learning mechanical ventilation waveforms. Hope that helps. Thanks for watching and commenting.
@@RespiratoryCoach now, how will I know if the square waveform on exercise means either pressure or flow?
I’m confused because if I decrease my tidal volume won’t my i time still stay the same unless I change it?
Does the square shape always refer to the PCV ?, because at the beginning of the passage you said that it refers to VCV?Or is there an exception? I used to think that the square shape indicates CMV whether it is PCV or is VCV. Please answer my question, my exam is in two days and I messed up? .

Sir you said square wave form always in volume control but when you solve mcqs you said square flow waveform are present in Pressure control
