Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Factors Influencing Duration

Individual response to treatment and the extent of vascular involvement affect the duration of disability. Duration depends on specific diagnosis and treatment.

Medical Codes

ICD-9-CM:
443.82 - Peripheral Vascular Disease, Other; Erythromelalgia
443.89 - Peripheral Vascular Disease, Other, Other; Acrocyanosis; simple [Schultzes type]; vasomotor [Nothnagels type]; Erythrocyanosis; Erythromelalgia
443.9 - Peripheral Vascular Disease, Unspecified

Prognosis

Overall, with treatment (thrombolytic therapy, angioplasty, bypass grafts, or thrombectomy), the immediate prognosis is reasonably favorable for improving blood flow and prevented amputation of the limb. Without treatment, limb loss may be imminent. The prognosis does vary somewhat depending on the specific type and cause of disease, and the stage at which it is first diagnosed. Treatment to bypass an obstructed vessel is generally not very helpful if atherosclerosis also affects smaller arteries beyond the site of blockage. Atherosclerosis underlying PVD is typically a progressive condition. It tends to recur and PVD tends to worsen following treatment unless there are significant lifestyle changes, including smoking cessation.

More severe cases may end in amputation of the effected lower limb. Amputation for atherosclerotic arterial disease in an upper limb is rare.

Individuals with atherosclerosis in limb arteries usually have the same disease in other arteries, and thus they have an increased mortality rate from events such as heart attack or stroke.
