Auscultation tips

Accurately identifying various heart, lung, and bowel sounds is an important part of any clinician’s repertoire. Being able to perform proper auscultation in optimal conditions will help you quickly assess your patients and monitor their condition with precision.

Tips to perform a proper chest auscultation:

  • chest auscultation areas

    Perform auscultation in a quiet, well-lit, and warm room. This allows effective amplification of heart sounds.

  • how to listen to heart sounds with a stethoscope

    Request for your patient to be appropriately disrobed. Having your stethoscope chestpiece placed directly on your patient’s chest or back will eliminate distortions and frictional noise from clothing.

  • lung and chest auscultation

    Examining your patient while he or she is supine, seated, and in left lateral recumbent positions will help you hear different sounds, especially abnormal ones, by accentuating them in different positions.

  • how to use a stethoscope to listen to lungs

    Repeat the steps using a stethoscope bell (see video below for conversion steps)  to help you listen for murmurs. Having a stethoscope with both a bell and a diaphragm, such as the 3M™ Littmann® Cardiology IV™ Stethoscope and the 3M™ Littmann® Classic III™ Stethoscope, can help you immensely with this.
