Acute limb ischaemia (ALI) occurs when there is a sudden lack of blood flow to a limb [1] within 14 days of symptoms onset. [2] On the other hand, when the symptoms exceed 14 days, [ 3 ] it is called critical limb ischemia (CLI).
Grade 2: deep ulcer with exposed tendon or bone, gangrene limited to toes; Grade 3: extensive, full-thickness ulcer; gangrene extending to the forefoot or midfoot; Ischemia is graded 0 through 3 based on ABI, ankle systolic pressure, and toe pressure. [66] Grade 0: ABI ≥0.80, ankle systolic pressure ≥100 mm Hg, toe pressure ≥60 mm Hg
In a limb with a normal circulation the toes and sole of the foot, stay pink, even when the limb is raised by 90 degrees. In an ischaemic leg, elevation to 15 degrees or 30 degrees for 30 to 60 seconds may cause pallor. (This part of the test checks for elevation pallor.) A vascular angle of less than 20 degrees indicates severe ischaemia. [1] [2]
APACHE II ("Acute Physiology and Chronic Health Evaluation II") is a severity-of-disease classification system, [1] one of several ICU scoring systems.It is applied within 24 hours of admission of a patient to an intensive care unit (ICU): an integer score from 0 to 71 is computed based on several measurements; higher scores correspond to more severe disease and a higher risk of death.
SAPS II was designed to measure the severity of disease for patients admitted to Intensive care units aged 18 or more.. 24 hours after admission to the ICU, the measurement has been completed and resulted in an integer point score between 0 and 163 and a predicted mortality between 0% and 100%.
An ABPI between and including 0.90 and 1.29 considered normal (free from significant PAD), while a lesser than 0.9 indicates arterial disease. [14] An ABPI value of 1.3 or greater is also considered abnormal, and suggests calcification of the walls of the arteries and incompressible vessels, reflecting severe peripheral vascular disease .
[1] [2] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia. [1] Depending on the extent of ischemia, symptoms of arterial occlusion range from simple soreness and pain that can be relieved with rest, [3] to a lack of sensation or paralysis that could require amputation.
