Use a BP Monitor? Use a Stethoscope ?		How Airtight is YOUR Stethoscope? Take this test and see. Turn the chestpiece so that you enable the bell (hole is under bell opening). Connect the stethoscope to your ears. Put one finger over the chestpiece bell hole to seal it. Lightly press on the diaphragm. Do you feel pressure in your ears when you press on the diaphragm? If you don't, the stethoscope is leaky. You should feel the pressure. Only when the air has nowhere else to go will it build up pressure in your ears.
