What is an essential factor when measuring the radial pulse?

Using proper technique and the non-dominant hand is crucial when measuring the radial pulse. This approach allows you to accurately detect the heart rate without inadvertently applying excessive pressure or altering the pulse rhythm due to the dominant hand's strength. The non-dominant hand is often more sensitive to subtle changes in pulse characteristics, which can be important for assessing the patient's cardiovascular health.

Measuring the pulse for a full minute provides a more accurate assessment than a shorter time frame, as it helps to capture potential irregularities or variations in the heartbeat that might occur over a longer period. Other methods, like using a thumb for pressure, can falsify the reading since thumbs have their own pulse, which may interfere with the accurate detection of the radial pulse. Additionally, using blood pressure measurement techniques, which often require firmer pressure, would not yield reliable pulse readings as the goal is to palpate and feel the pulse gently to avoid occluding the artery.
