Did you know  that a lot of the heart and lung sounds you hear as "normal" could be "abnormal"? A leak in your stethoscope can make the ejection sound & systolic murmur of  Mild Aortic Stenosis sound normal.

 Unfortunately, you have no way of knowing, but in 2 minutes you could know!

Mild Aortic Stenosis

This  leak makes the ES & SM inaudiable. You now hear only the S1 & S2, as a normal heart sound.  (These leaks can be detected and most of them you can fix.)

Up to 45% of stethoscopes leak, causing you, not to hear abnormal heart and lung sounds. Leaks let in room noise and also masks the abnormal sounds. (Expensive new stethoscopes can also leak.) 

Your stethoscope needs to be tested now! It takes less than two minutes. Test it every 60 days.    See  "Test Your Stethoscope" .      (We do not sell stethoscopes)
