So, that reason that PCV- VG was invented. Volume granted, or granted volume with pcv benefits. For planned elective surgery, I prefer PCV- VG mode for good lung protection, less changes in capnometry, normocarby, higher adoptation, less overload to heart. Is neurosurgery, including emergency neurosurgery, general surgery, vascular surgery, maxillofascial surgery, oftalmology, otolaringology, urology. For thoracical surgery, with one lung vent, for emergency surgery is better VCV. Simple. Controlable. All reliable. When lung is compromised on the different reason. When you must ventilate at any cost, ICU fix consequences after you if need, your choose is VCV. But not forget. For proper gas diffusion volume is not enough.
calculation is 6-8ml/kg IBW. So, he calculated the guy's height in cm (30.5 cm for each foot)= 183cm. then use that for IBM [(183-152.4) * (0.91)] + 50 = 77.8 then use 77.8 and multiply by 6-8ml 77.8 * 8ml = 622ml .622 L * 14 RR= 8.7 L/min THAT'S HOW HE GOT THE ANSWER WITHOUT TELLING US!!!!
Tidal volume formula =6 to 8 mls x kg Weight 85kg Tidal volume is 510 - 680 mls Minute volume formula =tidal volume x RR Normal RR is 16 to 20 bpm Estimated minute volume for this case Tidal volume (510) x RR (16) = 8160ml/ min 8.16L / min
The formula is valid WHEN FLOW IS ZERO. But even in that case it's probably a bit too general for caregivers and easy to misinterpret. In pressure controlled modes you have approximately tidal volume = (p insp - peep) / lung compliance. More generally: pressure = flow*lung resistance + volume/lung compliance. Resistance and compliance are estimated by modern ventilators and are shown as R and C. Especially C is, however both time and volume dependent. For that reason ventilators estimators "different kinds of C" like Cdyn and Cstat
This is so wrong. In the 1990s you did volume controlled ventilation. nowadays you should do pressure controlled ventilation beacause of the damage you can do to the lungs.
Incredibly simplified concepts, keep up the great work guys, highly recommended course
do you have a video focusing on pressure control?
Amazing explanation! Thank you!
Fabulously presented! Thank you so much.
Thank you! Clear with the tyre
This video is really helpful....keep in what you doing 👍😊😊😊
Can we determine how much tidal volume we deliver during PCV?
Yes we can, meaning we can still calculate the Minuet Ventilation. Not so?????
Height is 185 cm and Weight is 85 Kg , how do you can to conclusion that patient will require 8.40 L / minutes? Could you please explain ?
Thanks
My fav video on this topic.
Thx allot 4 ur great info

How could you get the 8.4 L/min
...Exactly, I don't get that.
calculation is 6-8ml/kg IBW.
So, he calculated the guy's height in cm (30.5 cm for each foot)= 183cm.
then use that for IBM [(183-152.4) * (0.91)] + 50 = 77.8
then use 77.8 and multiply by 6-8ml
77.8 * 8ml = 622ml
.622 L * 14 RR= 8.7 L/min
THAT'S HOW HE GOT THE ANSWER WITHOUT TELLING US!!!!
Tidal volume formula =6 to 8 mls x kg
Weight 85kg
Tidal volume is 510 - 680 mls
Minute volume formula =tidal volume x RR
Normal RR is 16 to 20 bpm
Estimated minute volume for this case
Tidal volume (510) x RR (16) = 8160ml/ min
8.16L / min
Great video sir
Kindly provide written file in this topics.....
Спасибо большое ❤
Thank u sir...
Can you determine pressure from formula PV=nRT?
The formula is valid WHEN FLOW IS ZERO. But even in that case it's probably a bit too general for caregivers and easy to misinterpret.
In pressure controlled modes you have approximately tidal volume = (p insp - peep) / lung compliance.
More generally: pressure = flow*lung resistance + volume/lung compliance.
Resistance and compliance are estimated by modern ventilators and are shown as R and C. Especially C is, however both time and volume dependent. For that reason ventilators estimators "different kinds of C" like Cdyn and Cstat
I understand 😊,tq sir
This guy's making cotton mouth noises XD
Not hating though, this helped a ton :)
Thank u !!!!
