How Does Pulse Oximetry Work?
Pulse oximetry is a non-invasive medical test used to measure the oxygen saturation level in a person's blood. It is commonly used for babies to monitor their oxygen levels and ensure they are getting enough oxygen. But how does pulse oximetry actually work?
Pulse oximeters work by using sensors and light absorption to measure oxygen saturation. These devices consist of a probe that is typically attached to a baby's finger, toe, or earlobe. The probe contains two types of light-emitting diodes (LEDs): one emits red light, and the other emits infrared light.
When the pulse oximeter is placed on the baby's body, the red and infrared light from the LEDs passes through the skin and blood vessels. Hemoglobin, the protein in red blood cells that carries oxygen, absorbs different amounts of red and infrared light depending on its oxygen saturation level.
The pulse oximeter detects the amount of light that is absorbed by the hemoglobin and calculates the oxygen saturation level based on this information. It compares the ratio of red to infrared light that is transmitted through the blood vessels to a reference value and provides a numerical reading of the oxygen saturation level.
In summary, pulse oximetry works by shining red and infrared light through the skin and measuring the amount of light absorbed by the oxygen-carrying protein in the blood. This measurement helps healthcare professionals assess a baby's oxygen levels and determine if any intervention is needed to improve oxygenation.
