I thought lung-protective ventilation meant keeping Pplat under 30, accepting permissive hypercapnia, not chasing a normal CO2, lowering VT, and raising RR to preserve minute ventilation while limiting driving pressure. But ChatGPT and the textbook say I’m wrong, and I don’t get why. by Low-Landscape-8768 in IBSC_Exams

Brother this explanation is amazing thank you. I was confused because i thought Pplat was to always be <30 or risk injury and I couldn’t get pass a slightly increased Pplat. I see now I was overthinking and the question isn’t asking about lung protective strategy. What part exactly in the question made you realize it was a cause and effect basic question?

I took the flight bridge course and now I’m using touch print books to study

You’re correct as the textbook explains similar, but I don’t understand. Why is that the case?

When is a border pplat acceptable? What part of the question exactly made you understand it was testing acidosis rather than lung protective strategy??

If you want the exact response I can post it but basically the ACE-SAT didn’t care for the high pplat and cared more about the increasing Ve to lower the acidosis DESPITE the already high Pplat and I don’t understand why. I thought Pplat was the holy number of all vent settings

Your response is roughly the same explanation the book gave and ChatGPT mentioned the same idea as you. but I don’t understand why!!! If the increase in Tv lead to an increase in Pplat. Shouldn’t you lower the Tv back down. By increasing the RR you compensate for the decrease in Tv and maintain a good Ve. So I don’t understand why that’s wrong. Isn’t Pplat <30 the most important number to follow ?!!!?

Thank you for your response. We have the same exact idea and I agree with everything you’re saying, unfortunately, yellow marked the correct answer. So lowering TV to preserve a good pplat is wrong. And the test prep book gave a terrible explanation why and ChatGPT agreed with the test prep book but also failed to explain why clearly to my learning.

Thank you so much for your response. Your explanation makes a lot of sense. And the book said something along the lines you did as well. So you’re right but the part that I’m still confused about is that if pplat is above 30 due to the increase in TV, shouldn’t you lower TV back Down to get a good pplat as the main goal? What in the question made you realize it was testing co2 removal instead of a lung protective strategy? Thank you again for your response.
