What Is Spo2
Blood oxygen saturation (SpO2)
Blood oxygen saturation SPO2 can be divided into the following components: S refers to saturation, P is the pulse, and O2 is for oxygen. The acronym measures the amount of oxygen attached to hemoglobin cells in the blood circulatory system. In simple it is the amount of oxygen carried by red blood cells. This measurement tells how efficiently a patient breathes and blood flows throughout the body. Oxygen saturation uses a percentage to illustrate the results of this measurement. The average reading for a normal healthy adult is 96%.
What is it?
Usually, we use the pulse oximeter to monitor blood oxygen saturation. The system includes a monitor and finger cuffs (spo2 sensor), which can be clipped onto the patient's fingers, toes, nostrils, or earlobes. The monitor displays a reading indicating the amount of oxygen in the patient's blood. As the oxygen concentration in the blood decreases, the signal strength decreases. The monitor also displays heart rate and has an alarm that signals when the pulse is too fast or slow. Or the saturation is too high or low.
What does it do?
Oxygen saturation devices measure oxygenated and deoxygenated blood with two different frequencies - red and infrared. This method is called spectrophotometry. Red frequencies measure desaturated hemoglobin, and infrared frequencies measure oxygenated blood. If infrared frequencies display the maximum absorption, it indicates high saturation. Conversely, if the absorption maximum is in the red band, it means low saturation.
How does it work?
Light transmits through the finger and is received by a receiver. Some of the light is absorbed by tissue and blood. When arteries fill with blood, absorption increases. Similarly, when arteries are empty, the level of absorption decreases. Since the only variable in this application is the pulsatile flow, the static part (such as skin and tissue) can be subtracted from the calculation. Therefore, using the two wavelengths of light collected in the measurement, the pulse oximeter calculates the spo2 level.
When the oxygen pressure increases, so does the hemoglobin saturation level. The hemoglobin reaches a maximum volume of 105 or more. The partial pressure of oxygen is useful for the partial pressure assessment of oxygen by measuring blood oxygen saturation.
97% saturation = 97% pO2 (normal)
90% saturation = 60% pO2 (dangerous)
80% saturation = 45% pO2 (severe hypoxia)
