What is tissue oxygenation?
tissues in the human body receive oxygen from the lungs over the roads of capillaries that branch from the arteries throughout the body. These capillaries supply oxygen to the blood that carries this oxygen and nutrients to different parts of the body. By replacing the capillaries, carbon dioxide and the waste gases load from the tissues and supply them through the blood that is pumped back into the lungs through the veins to be excluded when a person exhales. When the tissues absorb oxygen from red blood cells, this oxygen differs to cellular levels and energizing cells with life -giving oxygen. If tissue oxygenation is not enough, cells in organs, muscles and other parts of the body may die, causing life -threatening disease.
The need for the physical needs of different levels of tissue oxygenation is related to several factors. When the body is healthy and in a relaxed state, the perception of oxygen needed in the tissues can be approximately 25%. Athletes and workers while stressing their bones and goingIn demanding tasks with huge effort, they can experience an increased need for an oxygen level of almost 75%. Other factors that affect the need higher than the usual consumption of oxygen may include body heat due to fever or hot climate, because with each degree of temperature increase is needed more oxygen. At the opposite end of the spectrum, vibrations at cold temperatures are used rapidly by oxygen, which requires more frequent supplementary. In addition, any inflammation throughout the body increases the need to oxygenate the body to suppress unusual body heat.
If the body tissues constantly do not exchange oxygen and waste gases, the function will cease to function normally. Wounds can be radically slower to heal and infections can adjust the killing of cells and tissues, affect the organs and circulation on the limbs. The brain cells will die of oxygen in a few minutes, but the smooth muscles in the bladder may pass the days without sufficient oxygen. If heart dispensing disrupts the transport of oxygen to organ tissues andIn the entire circulatory system due to a reduction in blood flow, immediate medical care, including drugs and oxygen therapy, is required. Mini-embolisms in capillaries that block blood flow or large clots in arteries may also leave tissue oxygenation at a critically low level.
The closest therapeutic objectives in patients with insufficient tissue oxygenation are the restoration and maintenance of blood flows to vital and sensitive organs. Some medicines may improve the flow of circulation in some areas of the body and sometimes surgery to remove clots if there is not enough time to save organs or limbs without them. Doctors can also use fans to ensure that the body gets enough oxygen until patients are healthy enough to breathe in sufficient oxygen per Tědic.
