Pulse Oximeter
Pulse Oximeter or blood oxygenation is a device that can measure the percentage of oxygen saturation in human arterial blood.
Pulse oximetry is a non-invasive method that measures the amount of hemoglobinmolecules that are mixed with oxygen. The normal rate is 95-97%, if the rate in patients is less than 90%, an alarm sounds. Most pulse oximeters also displayheart rate .By this device it is possible to warn of hypoxemia(reducing oxygen levels)and improving patients by avoiding hypoxia attacks and their outcomes. Hypoxemia occurs when a patient is given localized or sedative anesthetics or when the patient becomes aware of a general anesthetic. This device was introduced in 1980 and now functions as a standard method.
