Hello guys,
Ok let's say there is a man with fluid in his lungs. You put a chest drain (intercostal tube). How does it drain?
1. Since the container is below the chest, when the guy expirates due to high pressure does fluid just flow to container? Can there be any retrograde flow (since container is below on the floor does gravity prevent this)
2. The article I read says with intercostal tubes, look at the water level of the container. In inspiration it must rise, and it must fall in expiration. If this doesn't happen tube is not working. What water are they talking about and also why does this phenomenon happen.
Thanks
