Background: The accuracy of a new optical biosensor (OB) point-of-care device for the detection of severe infections is studied.
Methods: The OB emits different wavelengths and outputs information associated with heart rate, pulse oximetry, levels of nitric oxide and kidney function. At the first phase, recordings were done every two hours for three consecutive days after hospital admission in 142 patients at high-risk for sepsis by placing the OB on the forefinger.
