Measurement of Blood Measurement of Blood PressurePressure
Auscultation (Korotkoff sounds):Auscultation (Korotkoff sounds):
1.1. onset of the sound (onset of the sound (systolic pressuresystolic pressure))
2.2. murmur or swishing sound occurs as the murmur or swishing sound occurs as the cuff deflatescuff deflates
3.3. crisper and more intense tappingcrisper and more intense tapping
4.4. muffled and low-pitched as the cuff is muffled and low-pitched as the cuff is further deflatedfurther deflated
5.5. absence of sound (absence of sound (diastolic pressurediastolic pressure))
