The signs of PAD

PAD is a progressive and deadly chronic condition, which left untreated, can lead to adverse patient outcomes. Discussing potential PAD symptoms with patients, and testing for PAD at the point-of-care is one of the best strategies to enable the widest range of PAD treatment options for patients, improving outcomes and lowering healthcare costs.

PAD Starts With Atherosclerosis

Atherosclerosis is the result of the accumulation of fibrous and lipid materials in the arterial walls. These materials are sometimes referred to as plaque or calcium deposits, and result in decreased blood flow. If this decreased blood flow, or arterial insufficiency, is experienced in the lower extremities, it is referred to as peripheral artery disease (PAD),  sometimes as peripheral vascular disease (PVD), and sometimes as peripheral arterial occlusive disease (PAOD).

Typical First PAD Symptom - Claudication

Oftentimes atherosclerosis progresses to PAD resulting in atypical symptoms, where a patient suffering from poor circulation due to atherosclerosis would be asymptomatic. If the PAD is not treated at this stage, the typical progression of the disease results in the patient experiencing intermittent claudication.  Claudication is when a patient has exertional pain in the legs  while walking, which is relieved at rest. Intermittent claudication is typically thought of as the first classic symptom of PAD.

Critical Limb Ischemia

As PAD progresses, the leg pain caused by poor circulation can result in a more advanced symptom of resting leg pain. This stage of PAD is oftentimes referred to as Critical Limb Ischemia (CLI), or Critical Limb Threatening Ischemia (CLTI). This pain typically manifests in the feet first, and more often at night, because leg elevation decreases blood flow.

Peripheral Artery Disease


To ensure proper healing potential from lower extremity wounds, your body needs a supply of oxygenated blood. If circulation to the legs is compromised then cuts and other lesions may be slow to heal, a common sign of PAD. These slow-healing wounds are more susceptible to infection.

PAD Testing

Performing PAD testing with the Biomedix PADnet® is a fast and clinically-relevant way to help identify PAD that provides fair financial reimbursement. A medical assistant typically performs the test, generating PAD clinical measures such as ankle brachial indexes (ABIs), pulse volume recordings (PVRs), toe brachial indexes (TBIs), and segmental pressures, either at-rest or post-exercise.
