8. Have the sphygmomanometer clearly visible.
9. Locate the radial artery, and then inflate the cuff. When you no longer feel the pulse, inflate the cuff another 30mmHg. This prevent cuff inflation to an unnecessarily high pressure which is painful to the person. (You can deflate the cuff at this time and note the point where you feel a pulse. Wait 30seconds and inflate the cuff 30mmHg above the point.
10. Measure the systolic and diastolic pressure. Expect to hear the 1st BP sound at the point where you felt the radial pulse. The 1st sound is the systolic pressure. The point where the sound disappears is the diastolic pressure.
11. Take the BP again if you are not sure of an accurate measurement. Wait 30-60seconds before repeating the measurement.
12. Notify the nurse in charge if you cannot hear the BP
