Radial Pulse

Exams and Signs

Historical Overview

  • Taking patients radial pulse is useful to examine neurovascular injuries and to determine if their heart is functioning properly.  If patients have undiagnosed irregular pulse rates, they should see a primary care physician.

Description

  • The radial pulse test monitors the neurovascular health of the patient. Pulse volume recordings (PVR) measure flow through an artery. A healthy pulse should be in the range of 60–100 beats per minute (bpm). 

Pathophysiology

  • Deviations from normal triphasic wave patterns arise from diseased arteries.

Instructions

  1. Use a Doppler to monitor the radial pulse
  2. Observe whether the pulse is in the range of 60–100 bpm
  3. Observe whether the pulse is steady

Variations

  • Check the pulse at the dorsal branch of the radial artery and the ulnar artery 

Related Signs and Tests

  • Ulnar pulse
  • Allen’s test

Definition of Positive Result
  • A positive result occurs when the patient’s radial pulse is irregular or outside the range of 60–100 bpm. 
Definition of Negative Result
  • A negative result occurs when the patient’s radial pulse is steady and inside the range of 60–100 bpm. 
Comments and Pearls
  • To achieve an accurate pulse reading, check that the patient is in a relaxed state.
  • Caffeine intake may also affect pulse rate.
