The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Hand Hygiene:
• Begin by performing hand hygiene to prevent the transmission of microorganisms.
Preparation:
• Identification: Verify the patient's identity to ensure accurate and safe care.
• Determination: Assess the need for pulse measurement based on the patient's condition.
• Equipment Arrangement: Gather a watch with a second hand, a pen, a vital signs flowsheet, and personal protective equipment (PPE) if necessary (e.g., gloves if there's a risk of blood or bodily fluid exposure).
Approaching the Patient:
• Procedure Explanation: Inform the patient about the purpose and steps of the procedure to ensure their comfort and cooperation.
• Positioning: Have the patient sit or lie down in a supine position. Ensure the patient's arm is supported and relaxed, avoiding elevation above heart level as it can affect pulse measurement.
Locating the Pulse:
• Utilize the pads of the index, middle, and ring fingers to locate the radial artery on the patient's wrist, just below the thumb base and adjacent to the wrist bone.
• Apply gentle pressure in the artery groove until the pulse is palpable.
Assessment:
• Evaluate the pulse's rhythm (regular or irregular), strength (strong, weak), and amplitude.
• Count the pulse rate for one full minute to obtain an accurate measurement. Any irregularities must be noted.
Bilateral Comparison:
• Compare the pulse readings bilaterally (on both wrists) to check for any discrepancies indicating vascular abnormalities.
Post-procedure:
• Guide the patient to a comfortable position, perform hand hygiene, and replace used items.
