A companyâs inventory turnover ratio refers to how quickly goods enter and leave storage at the business. Itâs most often used in relation to companies that deal in perishable goods, such as foodstuffs, or high-demand retail items. Itâs easy to calculate in theory, but itâs not always easy to interpret.
The retina is the light-sensitive layer at the back of the eye that is responsible for vision. Blood circulation to most of the retina's surface is primarily through one artery and one vein. If either blood vessel or one of their smaller branches is blocked, blood circulation to the retina can be significantly disrupted. The blockage is called an occlusion.
PAD is a medical condition caused by blockages of the arteries that provide blood flow to the arms or legs. You may have also heard of this problem referred to as peripheral vascular disease (PVD) or âbad circulation.â In PAD, the arteries become blocked by cholesterol plaque caused by atherosclerosis.ecause PAD-related blockages in the arteries limit blood flow to the legs, patients with PAD have low blood pressures in the ankles. Your physician will use the ratio of the leg pressure to the arm pressure (ankle blood pressure divided by arm blood pressure) to determine whether you have PAD.
