Oxygen is needed by the body to move. However, there are times when the body can not be forced to get normal oxygen supply, such as when a person undergoing a surgical procedure.
Now, to prevent the body is deprived of oxygen, recently researchers from the University of Tokyo said they are developing electronic devices 'skin' or E-skin that can calculate the oxygen levels in the body. Use of this tool aims to help monitor the oxygen levels in the organ during surgery.
Researchers revealed, E-Skin is now in the stage of human testing. Mentioned, the device contains a micro-electronic components which will glow red, blue, or green on the body surface. Currently, E-skin has reached the stage to show the numbers and letters on the skin for health monitoring purposes.
"E-Skin measure the concentration of oxygen in the blood, when glued to the finger," said lead researcher Tomoyuki Yokota, quoted by the BBC
Tomoyuki added at the end, a flexible organic optical sensors would be bonded to the organ you want to see the levels of oxygen, so that the blood oxygen levels during and after surgery can be monitored.
Some time ago, an expert in neurosurgery from Medistra, Dr. Arief M Radhian SpBS, said when the brain is deprived of oxygen it happens cerebral hypoxia. People who are susceptible to this condition include pasiem stroke. That is if there is a blockage in the blood vessels of the brain that blocks blood flow and oxygen can not be delivered to the brain.
"Brain tissue is a tissue that can be called spoiled by the need for oxygen. The brain is in desperate need of oxygen in considerable amounts. Lack of oxygen weight will also make brain swelling. The result will press against the brain stem that lead to death," said the man who is familiarly called Dr. Andra this.
Short-term effects of cerebral hypoxia include compensating effect of other organs that are trying to restore the adequacy of oxygen in the brain. Dr. Andra cited increased respiratory rate, heart rate quickened, the body feels weak because the levels of oxygen to other body parts is reduced to insufficient supply to the brain. If this can not be addressed, it could lead to the death of brain tissue. In addition it could malfunction or a paralysis of function in accordance with the location of dead brain function.
