Principles of Mech Vent 12: Inspiratory Time in Pressure Control: How to use the Flow Waveform!

[@wa590]

You explained to me in a few minutes what my professors couldn't do in 2 weeks .. they somehow just expected to understand all of this w/o teaching it to us. Thank you! Liked and subscribed!!

[@stray_dog3960]

I don't know if you are still keeping up with these videos but you are doing wonders for students in the RT world, keep the good work up you are making us smarter.

[@rhoffmanrn]

This was freaking awesome. Seriously as soon as it finally clicked I stood up and yelled I’m the smartest person alive!!! Thank you

[@RespiratoryReview]

Really glad it helped!

[@RespiratoryReview]

Michelle: In pressure control you don't have the option of increasing/decreasing the flow, like you do in volume control. It is not a variable we decide on in pressure control, the flow rate will be the result of the pressures we set, and the patients lung mechanics etc.

[@youthonly3988]

A fantastic explanation!! Love the Mech Vent series. Have not watched the others yet but surely will. Just preparing for my first on-call and this explains stuff so clearly. Thank you so much.

[@RespiratoryReview]

I remember my first on call! You’ll be fine. Glad you like the videos.

[@mindfulnessmusicsound]

Your vídeos are awsome man. Please, don't stop on doing it... it's benn heloing me a lot

[@SixStrings187]

perfectly explained. Thank you very much !

Thank you,this was very helpful.

you are my hero

[@mohammedparveez5603]

Well explained

Amazing 🎖

[@hebamoneim8896]

Amazing ! Thanks a lot

[@user-jw2ej1uf1j]

Thanks alot it was so useful

[@rtstudent2752]

Great videos! I think I'm over thinking it, (I do that a lot), but if flow is decreasing how do we maintain the pressure throughout Ti. ?

[@Suzi_P]

Thanks so much

[@Rene-uz3eb]

I hope these vents when backstopping at say 14 breaths a minute stop that automatic cycle if the patient breathes on their own, rather than superimposing assisted breaths with the backstop breaths.

[@Rene-uz3eb]

Nope, they don't. Only when there is overlap of assisted breath with automatic breath

[@rotorfib8719]

how do you 'picture' things if your vent doesn't have the waveform graphs, like the lvt series

[@jeant9946]

Hi, do you mind telling us what kind of equipment and app did you use for making the video? I would like to do similar thing but in my own language. thx u

[@algorean]

I don't know whether you're still active on the channel but I wanted to ask if the last graph can be a case of inspiratory pause, and how can this help the patient.

[@MissRateil]

There is no inspiratory pause in pressure control ventilation. There is equilibration that can be reached by increasing insp. time.

[@math11as]

hi there does Ti means we got to hold that 20mmhg for 1sec? or does it mean at the end of Ti we have a pressure of 20mmhg? + i do not understand how there can be added extra volume to the lung (left waveform) without raising the pressure? more volume= more pressure right?

[@stevenr672]

If the pt is breathing over the set vent rate on PC, are they being supported more in PC, than switching them over to PS...

[@javaidhassan3921]

Acid base balance basic concept

[@23dfmahghd]

What is the name of the application that you use for explanation

[@raulz77]

I could not find Video number 11. Can you tell where is it ?

[@abdulmajeedbaogbah4482]

Thank you for this video. Instead of increasing the (i time), can we increase the inspiratory rise? If not, what’s the relation between inspiratory rise and the amount of volume?

[@cuff2860]

I'm still a student so I may not be accurate but I'm fairly certain that increasing inspiratory rise would be the same as increasing the flow. Instead of a smaller, more gradual rise, the flow would come faster. That faster speed would equal increased oxygenation because it would be in the alveoli longer, which means for a greater period of diffusion.

[@Rene-uz3eb]

8:57 I disagree that this was potentially lost lung volume. Flow is already minimal by this time, so it's more like you're wasting time, not air, if you waited until lungs were at capacity. If you want to get a proper answer you need to formulate this as a gas flow maximization problem and mathematically optimize it. Though the optimal solution probably won't make a big difference.

[@rationalclinicalmedicine9732]

Very informative pls send me link for all videos on mechanical ventilation

[@RespiratoryReview]

You’ll find all the mechanical ventilation videos in the playlist called “Principles of Mechanical Ventilation”. You can copy links to the whole playlist or individual videos there. Thanks
