Lesson

For heart sounds listen to the synthetic sound while reviewing this lesson.

Diminished vesicular sounds are of lower intensity and are less full or robust than vesicular sounds. These sounds can occur in patients who move a lowered volume of air, such as in frail, elderly patients or shallow breathing patients. They are also heard with obese or highly muscular patients, where tissue mass impedes sound. They exhibit a normal inspiration to expiration ratio of 3 to 1, or 4 to 1.

As you listen to this sound, observe the waveform. This is a graph of sound amplitude (loudness) on the vertical axis vs time on the horizontal axis.

Additional Listening Tips

Lower intensity than bronchial sounds, normal inspiration to expiration ratio of 3 to 1 or 4 to 1.

Auscultation Method

The recommended patient position is sitting

For this sound, use stethoscope's diaphragm The recommended auscultation position for the stethoscope is posterior-3l
