It's not until after she dies that Scout and Jem get a sense of what's going on behind the drool and venom: Mrs. Dubose is a morphine addict who had vowed to go clean before she died, and enlisted Jem and Scout (without their knowledge) to keep her off the stuff for longer and longer periods of time.
http://lungsounds.net/rales-lung-sounds/ - Rales lung sounds are small rattling noises heard around the lung. This happens when air exposes closed air spaces. Rales can be shown as wet, dry and coarse.
Usually the COPD patients are diminished. Some to the point that you barely hear lung sounds at all. CHF patients are usually the ones that sound wet (they need lasix IV when its that bad). They can have various sounds depending on how sick they are.Usually you will hear rhonci and rales.ales and crackles are the same, they mean it sounds wet and crackly. Rhonci sound like leather rubbing together. Pneumonia patients may have a smorgasborg of sounds. I have also heard pneumonia patients that lung sounds are pretty much clear, but the xray shows infiltrates.
