Listening carefully to the Korotkoff sounds as you deflate the blood pressure cuff, you detect the first sound at 146 . It continues until 94, when the sounds are muffled, and eventually the sounds disappear at 40
Using the recommended method, you record this blood pressure as a. 146/94 c. 146/94/40
b. 146/40 d. 94/40/0
C
Blood pressure is recorded as a fraction with the top number representing the systole (when the ventricles are contracting), and the bottom number(s) representing diastole (when the ventricles are relaxed and filling). If first and second diastolic sounds are recorded, the first diastolic sound is written over the second. In the question, the first sound heard correlates to the systolic pressure or 146 . It continues until the sounds are muffled at 94, which is the first diastolic reading. When the sound disappears at 40, this is the second diastolic reading. Thus, the blood pressure would be recorded as 146/94/40
