Pulselessness: A lack of pulse rarely occurs in patients, as pressures that cause compartment syndrome are often lower than arterial pressures. [5] Absent pulses occur only with arterial injury or late-stage compartment syndrome, when pressures are very high. [5]
The dorsalis pedis artery pulse can be palpated readily lateral to the extensor hallucis longus tendon (or medially to the extensor digitorum longus tendon) on the dorsal surface of the foot, distal to the dorsal most prominence of the navicular bone which serves as a reliable landmark for palpation. [3]
The posterior tibial artery pulse can be readily palpated halfway between the posterior border of the medial malleolus and the Achilles tendon. [1] It is often examined by clinicians when assessing a patient for peripheral vascular disease. It is very rarely absent in young and healthy individuals. [3]
The physical examination to diagnose cardiac arrest focuses on the absence of a pulse. [30] In many cases, lack of a central pulse (carotid arteries or subclavian arteries) is the gold standard. Lack of a pulse in the periphery (radial/pedal) may also result from other conditions (e.g. shock) or be the rescuer's misinterpretation.
Prevention is the first step in avoiding the development of an arterial insufficiency ulcer. These steps could include annual podiatry check ups that include, "assessment of skin, checking of pedal pulses (assessing for blood flow) and assessing physical sensation". [5]
Peripheral physical signs of aortic regurgitation are related to the high pulse pressure and the rapid decrease in blood pressure during diastole due to blood returning to the heart from the aorta through the incompetent aortic valve, although the usefulness of some of the eponymous signs has been questioned: [23] Phonocardiograms detect AI by ...
Typically, the blood pressure obtained via palpation is around 10 mmHg lower than the pressure obtained via auscultation. In general, the examiner can avoid being confused by an auscultatory gap by always inflating a blood pressure cuff to 20-40 mmHg higher than the pressure required to occlude the brachial pulse.

Decreased or absent pulses; Muscle atrophy or wasting; Noticeable blueness of the affected limb; Decreased temperature (coolness) in the affected limb when compared to the other; Thickened nails; Smooth or shiny skin and hair loss; Buerger's test can check for pallor when the affected limb is in an elevated position. The limb is then moved from ...
