The present disclosure is generally directed to maintaining sensor quality standards and/or preventing improper remanufacture of sensors, such as pulse oximetry sensors. Present embodiments may include a system for facilitating the monitoring of physiologic conditions that includes an optical reader configured to translate an optical machine-readable representation of data associated with a patient into electronic data, a memory device configured to receive and store the electronic data after an initial reading of the machine-readable representation of data by the optical reader, and a processor configured to associate the electronic data with historical data obtained from the patient and limit access to the historical data based on whether the optical reader provides matching electronic data based on a subsequently read optical machine-readable representation of data when predefined conditions are met.
