I am a fairly new RN working in Geriatrics and have to admit Breath sounds are a problem area for me. My residents are mostly no transfers. I have been working with a man who is failing quickly. I just have a hard time understanding and describing what I hear in his lungs. Am I right to assume that anything that sounds like a crackle, bubble, gurgle generally means fluid in some amount?? I hear so many different terms like crackles, rales, rhonchi, I am very confused by it all. What is the difference in crackles if it's heard on inspiration or expiration. We have always been told to just document it as we hear it. This guy had espiratory "crackles" to his lower left lung and expiratory "crackles" throughtout his right lung. (Sounds like bubbles to me) No transfer. So would Lasix and oxygen be warranted? I am usually the only RN in this facility per shift so there isn't anyone around for advice. I'd appreciate it if anyone could give me their course of action on situations like this and also describe these sounds to me.
