Fluid in the lungs..

[NyMe18]

I’m wondering if anyone knows..

If a person has fluid in their lungs, a smaller amount can these things be true:

- From the liquid appearing to the lungs absorbing it again could 4-5 hours be enough?
- Would the liquid be visible on an x-ray performed to see blood cloths, with contrast? I realize the contrast won’t show the liquid but the X-ray itself?
- Cause a full, deep breath to hurt but not regular more “shallow” breathing?
- Could the liquid come, be absorbed and then come again due to its original reason for being there being “triggered”?
- If it perhaps was cardiac asthma, would a heart preform normally on a test with electrodes that they put all over your chest but only keep on for what seemed like a second?

Are there any “lighter cases” of fluid in the lungs?

Thank you for any help <3
