A mechanism for storing and providing historical physiological data, such as blood oxygen saturation data, for a patient. In particular, the historical physiological data is stored in a storage medium that "travels" with the patient and is accessible wherever the patient is moved. This is achieved by storing the physiological data within a sensor assembly. At the destination site, a monitor or a device capable of interfacing with the sensor electronics can retrieve and display the data. The historical physiological data allows a clinician or medical personnel at the destination site to assess the condition of the patient for the entire time that the patient has been monitored. Various types of physiological data can be stored including, but not limited to, blood oxygen saturation, heart rate, and temperature data. Compression of the data can be performed to enhance the storage capability.

1. A physiological sensor for connecting to a first monitor, comprising:means for obtaining signals from a patient indicative of a physiological condition of the patient; means for sending the signals to said first monitor; and a sensor memory circuit associated with said physiological sensor and located outside any monitor which processes said signals, said sensor memory stores patient physiological data derived from the signals by said first monitor and which are indicative of the physiological condition, the sensor memory circuit providing the data to any monitor when requested by said any monitor, such that when said sensor is disconnected from said any monitor said sensor memory is physically connected with and moves with said sensor.
