By varying the pressure placed on the patient, a tunable diaphragm will adjust, or tune, the sounds to allow you to hear either low or high frequencies. When holding the tunable diaphragm on a patient and pressing lightly, low frequency sounds will be transmitted.
Use the diaphragm of your stethoscope to listen to your patient's lungs.
- As you listen place the stethoscope on the upper part of the chest, then the midclavicular line of the chest, and then the bottom part of the chest.
- Make sure to compare both sides of your patient's lungs and note if anything is abnormal.
