I have a question: most of us would agree that auscultating the stomach area for NG tube placement verification (the "whoosh test") is not reliable enough and we need to do either CXR or litmus paper test. BUT, when we used to routinely do it, and for those of us who still do it (at least for the preliminary verification while waiting for an X-ray): why are we not auscultating the stomach AND the lungs when we push that air from the syringe? At least to compare the sound? Or is it normal to hear the air sound in the lungs, even if the tube is actually in the stomach? I recently was able to hear the air (whoosh) in both the stomach AND the lungs (the sound in the lungs was actually more loud and pronounced than in the stomach) while my fellow nurse was waiting for an X-ray to come in (not sure how that ended--didn't have a shift scheduled with her in a while to ask). What do you, guys, think? Any experience with it?
