Pleural Rubs | Auscultation #34 | Lesson with Audio
The patient was seated during auscultation.
Description
When auscultation is performed, pleural rubs can often be heard as creaking or grating sounds. These are produced by two inflamed surfaces rubbing against each other - similar to walking on fresh snow or the sound of leather-on-leather. Coughing does not affect these noises and they will usually change in intensity with respiration cycle (aimilarly increasing at inspiration, decreasing at expiration). A crucial distinction between them and pericardial friction rubs is that those continue even when patient holds their breath whilst a pleural rub stops immediately thereafter.Waveform
