BP Measurement Auscultatory Tutorials

Click on the individual clips below to watch a video of a mercury column as the cuff deflates and listen to the Korotkoff sounds. Compare your answers with those on the Answer Sheet.  Note that some recordings are missing from the numeric sequence, i.e. 9, 13, 21, 28 and 29

These recordings have some typical artefactual sounds. Read using the top of the meniscus. If amplification with earphones is used, very soft continuous sounds can be heard earlier and later than using a standard speaker on some recordings, as indicated on the answer sheet. This can be relevant during auscultation using a better stethoscope and may also depend on auditory acuity and experience in sensing soft sounds.
