Finding a pedal pulse is part of the trauma patient assessment and is performed before and after lower extremity splint application, as well as long backboard immobilization. Assessing a pedal pulse is part of the ongoing assessment for an immobilized patient or a patient wearing a lower extremity splint. During hospital care, nurses and CNAs, might need to find and document lower extremity circulation for bed-bound patients.

Locating a pedal (foot) pulse can be difficult even in healthy patients. Use these tips to find and refind a patient’s pedal pulses:
1. Radial pulse first
Assess the patient’s radial pulse rate and rhythm so you know what you are seeking and palpating in the patient’s foot.
2. Bare the patient’s skin
Move shoes, socks, tights and anklets out of the way to expose the patient’s skin.
3. Reposition the foot to normal
Move, if not compromised by injury, the patient’s foot towards the normal anatomical position.
4. Two possible pedal pulse positions to check
Check for either the dorsalis pedis pulse (on the top of the foot) or the posterior tibial pulse (located behind the medial malleolus — the ankle bone).
5. Visualize skin for pulsation
For dorsalis pedis, first, visualize the patient’s bare skin because you might see the skin pulsating above the artery. If you are unable to see anything, hold two or more fingers lightly against the skin of the foot. Start your search just above the space between the great (big) toe and the second toe. Gently feel for a pulse as you move your fingers up from the toes towards the lower leg until you locate the pulse.
6. Use two or more fingers
For posterior tibial — on the medial side of the ankle — use two or more fingers. I find that more pressure is needed to find this pulse.
7. Try the other leg
If you are unable to find the pedal pulse on one leg, switch to the patient’s other leg. Knowing the location of one pulse might help you find the other.
8. Mark the pedal pulse location
Once you have found a pedal pulse, consider using a ballpoint or felt pen to make a light mark at the pulse location to make reassessment easier.
9. Check foot temperature and color
Finally, if the patient’s foot is warm with normal color, it is adequately perfused.
