stethoscopes - page 5
Hi, I just started an accelerated BSN program, and my lab instructor recommended that we go out and get a "GOOD" stethoscope, spending about $100. This caused a little debate among my classmates... Read More
Dec 23, '06Hi all. As a new nusring student, which is better to buy.... a single head or a dual?? I am not sure how a dual works.
Dec 23, '06hi, here is some information on dual-sided or dual head stethoscopes:
they enable simultaneous amplification of certain critical physiological sounds, by alternation between the two differently-shaped and differently-sized sound collecting areas. the "bell" side is not more or less suitable for pediatric use than the diaphragm side. the "diaphragm side" is generally more sensitive to respiratory sounds than the "bell" side. high fidelity, dual-sided stethoscopes have greater sensitivity to all frequencies on both sides, than single-sided ones
there are so many 'scopes out there. i would suggest you either ask someone a wee bit more experienced than you or head over to a medical supply store and ask if you can check them out.
good luck with your schooling!
Dec 23, '06If you buy a cheap single head stethoscope, the one diaphragm will likely function just solely as one, however, if you buy a more expensive single-head stethoscope it can/may function as both.
From the Littman Website, about their single head stethoscopes:
Tunable technology provides convenience, versatility and enhanced acoustics. The dual frequency diaphragm combines both bell (low-frequency) and diaphragm (high frequency) into a single side of the chestpiece. You control bell and diaphragm modes by pressure on the chestpiece rather than by turning it over.
If you plan to buy a cheapie, might as well get dual-heads. If you get a more expensive one, then its personal preference.Last edit by S.T.A.C.E.Y on Dec 23, '06
Dec 24, '06I have both. I have a dual and a single and honestly, I use the single more than the double. It's easier to go from the bell to diaphragm with a simple amount of pressure or release of pressure. Both of mine are littman and I paid about $50 for each.
Dec 28, '06I bought Littmann Cardiology III on Ebay and love it. I now work in PED's and am glad to have the dual sided bell diaphragm style. Think of your stethoscope as a lasting investment. You WILL use it after nursing school, unlike some of those pricey books we needed to buy.
Jan 1, '07I also have a Cardiology III. I got it for Christmas and haven't had a chance to use it. But I'm hoping it will work well.
