Ischemia is the condition that arises from reduced blood supply to a tissue or organ, which results in decreased oxygen availability, or hypoxia. This scenario can occur due to various factors, including blockages in blood vessels or constriction that limits blood flow. When blood supply is diminished, the affected tissues cannot receive the necessary nutrients and oxygen, leading to potential damage or dysfunction.

Understanding ischemia is critical in both medical and emergency response contexts. It can lead to significant complications, particularly in vital organs like the heart or brain. In the heart, for instance, ischemia can present as chest pain or angina, and if it persists, it may progress to myocardial infarction—a more severe condition involving heart tissue damage due to lack of blood flow.

The other conditions listed, while related to blood flow or oxygen delivery issues, do not specifically define the situation of reduced blood supply leading to hypoxia in the way ischemia does.
