👉 Cachemia is a condition in which the body's oxygen-carrying capacity is decreased, leading to an excessive need for oxygen. It occurs when blood vessels become clogged with red blood cells, causing the blood volume to decrease and the lungs to work harder to provide more oxygen to the tissues. This can lead to severe symptoms such as shortness of breath, nausea, vomiting, chest pain, and confusion. Cachemia is a serious condition that requires immediate medical attention.
