How to count a manual pulse
· Some studies have examined the relationship between measurement duration and the accuracy of pulse-counting. A representative study by Jones () quantified the errors of pulse-counting at 15, 30 and 60 s. In that study, 58 nurses and 30 nursing students counted human pulse rates by radial palpation, which were then compared with the rates. · Inflate a BP cuff and count the bounces on the sphygmomanometer needle.
