What is the proper technique for taking a radial pulse?

To take a radial pulse accurately, the proper technique involves placing two fingers, typically the index and middle fingers, on the inner wrist, specifically below the base of the thumb. This method allows the caregiver to feel the pulse as blood is pumped through the radial artery, which is close to the surface at this location. Counting the beats over a specified time, usually for a full minute or 30 seconds with the count multiplied by two, provides the pulse rate.

Using a thumb to press down, as mentioned in another choice, may not yield an accurate reading because the thumb has its own pulse which can interfere with the assessment. Moreover, utilizing a stethoscope on the chest relates to auscultating heart sounds rather than obtaining a radial pulse. Pressing firmly on the arm with the palm may obstruct blood flow and inhibit the ability to feel the pulse itself. Thus, using two fingers to properly locate and count the radial pulse is essential for reliable results.
