$GTCH With a touch of a finger, beams of light measure the amount of oxygen in your blood by analyzing the color and movement of blood cells. Dark red blood cells indicate a lack of oxygen, while bright red blood cells indicate higher oxygen level. For example, if 96% of the blood cells are bright red, while 4% are dark red, then the Sp02 (Oxygen) level would be 96%. When a finger is placed on the qTerm device, a light source emits intense light. A light detector detects the light that passed through the finger, measuring how much was absorbed. A computer program performs an accurate calculation to produce numerical results. One of the main advantages of pulse and oxygen oximetry is the fact that it is a painless and noninvasive method. Oxygen saturation is an important measure to indicate proper functionality of our lungs. As we breath, our lungs pass oxygen into tiny blood vessels called capillaries. The capillaries transport oxygen-rich blood to our organs. The heart pumps the blood through arteries to the rest of the body to maintain constant supply of oxygen. In case of improper lung functionality, blood oxygen saturation declines, potentially putting our organs in danger. A pulse/oxygen oximeter can quickly detect a drop in oxygen saturation and alert for medical intervention.
