PULSE OXIMETER

A pulse oximeter is a small medical device used to measure the oxygen saturation level in the blood. It is commonly worn on the finger, although it can also be placed on the earlobe or toe. The device works by emitting light beams into the body, which are then measured as they pass through the blood vessels. By comparing the amount of oxygenated hemoglobin to the total amount of hemoglobin, the pulse oximeter can determine the oxygen saturation level. This information is crucial in monitoring the respiratory function of patients, particularly those with respiratory conditions or undergoing surgery. The pulse oximeter provides a quick and non-invasive method of assessing oxygen levels, allowing doctors to make informed decisions about patient care.
