Question: What are the five blood pressure phases and korotkoff sounds?

Traditionally, these sounds have been classified into five different phases (K-1, K-2, K-3, K-4, K-5) and are shown in the figure below. K-1 (Phase 1): The appearance of the clear “tapping” sounds as the cuff is gradually deflated. The first clear “tapping” sound is defined as the systolic pressure.

What are the phases of Korotkoff sounds?

The different Korotkoff sounds are identified by the character of the sounds, as outlined by Geddes et al. Phase I sounds are loud, with a clear-cut snapping tone; phase II sounds have a murmur-like quality; phase III sounds are similar in character to phase I sounds; and phase IV sounds have a dull or muffled tone.

What are the Korotkoff sounds and how do they relate to the identification of systolic and diastolic BP?

Korotkoff sounds are produced underneath the distal half of the blood pressure cuff. The sounds appear when cuff pressures are between systolic and diastolic blood pressure, because the underlying artery is collapsing completely and then reopening with each heartbeat.

What are Korotkoff sounds and what do they represent?

The sounds detected by the stethoscope in the auscultatory blood pressure measurement, known as Korotkoff sounds, are used to define systalic (high value) and diastolic (low value) pressures inside the arterial system.

What pressure is determined when Korotkoff sounds?

Then the air is let out of the cuff at a rate such that cuff pressure falls at a rate of about 5 mm Hg/sec. At some point the person listening with the stethoscope will begin to hear sounds with each heartbeat. This point marks the systolic pressure. The sounds are called Korotkoff sounds.

What are the 5 korotkoff sounds?

Korotkoff sounds (or K-Sounds) are the “tapping” sounds heard with a stethoscope as the cuff is gradually deflated. Traditionally, these sounds have been classified into five different phases (K-1, K-2, K-3, K-4, K-5) and are shown in the figure below.

How do you hear blood pressure sounds?

Turn the knob on the pump toward you (counterclockwise) to let the air out slowly. Let the pressure fall 2 millimeters, or lines on the dial, per second while listening for your heart sounds. Note the reading when you first hear a heartbeat. This is your systolic pressure.

What are the sounds of korotkoff quizlet?

Terms in this set (12) what is the sounds heard when measuring blood pressure, and what causes them and why they occur. korotkoff sounds. they are due to blood turbulence occurring in the brachial artery under the stethoscope diaphragm.

How does korotkoff measure blood pressure?

The medical practice of measuring blood pressure by constricting the upper arm and listening with a stethoscope to assess when the first sound and final sounds are audible dates back over 100 years ago. This method is still considered the gold standard for noninvasive blood pressure measurement.

What are the sounds heard using the sphygmomanometer and stethoscope?

A healthcare provider uses a stethoscope and a blood pressure cuff with a sphygmomanometer to measure blood pressure manually. The stethoscope is used to listen to the blood pressure sounds, which are called Korotkoff sounds.

Which phase of the Korotkoff sounds is documented as the systolic blood pressure reading?

Phase 1: A sharp tapping. This is the first sound heard as the cuff pressure is released. This sound provides the systolic pressure reading. Phase 2: A swishing/whooshing sound.
