Aveolar/Pleural Pressures...
If anyone can help me, I am having trouble getting the facts straight with positive/negative aveolar/pleural pressures with inspiration and expiration.
In inspiration I know that the aveolar pressure goes to -1 in mid-inspiration then to 0 at the end. In expiration it goes to +1 mid-expiration and then 0 again at the end. I guess I am just having trouble with pleural pressure and really just the main point. With pleural is it just comparing with the atmospheric pressure to determine whether you will have inspiration or not? Sorry I know if must seem so basic but it's a tricky point for me. Thanks in advance!
