What are Korotkoff sounds? What are its five phases?

  • Korotkoff sound represents arterial oscillation resulting from distension of the arterial wall with each cardiac impulse due to partial occlusion of artery by the cuff. 
  •  Low pitch sound
  • Five phases are
  • PHASE 1 - CLEAR TAPPING SOUND   (SBP)
  • PHASE II - ONSET OF SWISHING SOUND OR SOFT MURMUR
  • PHASE III- LOUD SLAPPING SOUND
  • PHASE IV - SUDDEN MUFFLING OF SOUND
  • PHASE V - DISAPPEARANCE OF SOUND / PHASE OF SILENCE (DBP)
  • "Tap - Murmur - Slap - Muffle - Silence"
  • It was described by Nikolai Korotkoff, a Russian surgeon in 1905
