Retinal hypoxia is implicated in a multitude of prevalent retinal diseases that are potentially blinding. Impaired retinal blood flow (RBF) and/or poor oxygenation are the unifying factors that lead to the blinding complications seen in the microvascular occlusive diseases (retinal artery and vein occl...
According to Hu Fenglan, director of the hospital's blood transfusion department, the drone service improves medical treatment efficiency and ensures a reliable blood supply during emergencies. Blood delivery via drones exemplifies one of the medical service application scenarios in Nanshan District, mark...
A stroke occurs when one of the blood vessels leading to the brain is blocked by a blood clot or bursts. This reduces blood supply to the brain and prevents oxygen from reaching it. Aortic Aneurysm Aortic aneurysms are a form of aneurysm that affects the body’s main artery. It indicates...
(with the exception of the camel, in which the erythrocytes are oval and lentiform). Increasing the number of erythrocytes and decreasing their size improves the oxygen supply to the body. In the lower vertebrates, 100 ml of blood contains 5–10 g of hemoglobin; in fish, 6–11 g; and ...
Chronic, poorly-controlled hypertension causes damage to the arteries in the body, from the largest, the aorta, to the smallest arterioles that supply blood to every organ in the body. Over time, the risk of damage to every organ increases. Hypertension is one of the major risk factors that...
there is no marked increase in PaCO2level in some infants as in adults with respiratory distress because many infants can still eliminate carbon dioxide from the lungs even though weakness prevents inhaling an adequate oxygen supply. All infants being ventilated and receiving oxygen therapy require fre...

The veins of the brain drain the blood from the entire brain as well as the surrounding structures (meninges, eyeballs etc). The drained blood is then first returned to the dural venous sinuses and then the internal jugular vein. Structurally, the veins of the brain lack a muscular layer ...
