Systems and methods for comparing a first patient's pulse oximeter data with a second patient's pulse oximeter data. The system of the present invention comprises a pulse oximeter device and a remoteserver. The method of the present invention comprises acquiring a first patient's pulse oximeter data and inputting one or more markers for various segments of the first patient's acquired pulse oximeter data. A second patient's pulse oximeter data corresponding to a known condition may be displayed with the first patient's pulse oximeter data and the one or more markers to aid the medical personnel in diagnosing the first patient's condition. After diagnosis, the first patient's pulse oximeter may also be simplified to allow the first patient to understand the pulse oximeter data.
