[Pulse oximetry monitoring of single lung anesthesia in non-cardiac thoracic surgery].

The pulse oximeter provides continuous and non-invasive measurement of the arterial oxygen saturation. Pulse oximetry contributes to safer patient management because of the immediate availability of oxygen saturation values. This is particularly important in high-risk anaesthesia such as one-lung anaesthesia. Pulse oximetry is as important as ECG monitoring and invasive blood pressure monitoring and should therefore be a standard monitoring technique in thoracic surgery. With a pulse oximeter it is possible to efficiently monitor anaesthesia during one lung ventilation thereby avoid hypoxia with its life-threatening complications.
