Help! I've learned all of the heart assessment auscultating spots ... but sometimes, I just can't hear a darn thing? I'll hit all the marks ... and still nothing... the stethoscope is working ... the patient is breathing, so I know the heart is beating. I mean, I hear nothing ... even if they turn toward the left? It doesn't matter if the pt is obese, though that probably compounds it, or thin. There are times I just can't hear it. Is this a technique thing, a hearing loss issue on my part

(I do doubt this, but am open to the possiblity), a hardware problem (standard cardiac littman), or is it possible that some patients' heart sounds are so faint that normal breathing silences it... Can I tell you how silly I feel even asking this question? So, Silly. Would appreciate any help, suggestions, or corroboration of this problem... Thanks...
