Patent ID: 7373193

Claim:
A physiological monitor and data capture system capable of real-time patient monitoring and data acquisition for post-monitoring off-site analysis, the system comprising: a sensor having emitters configured to transmit light of at least first and second wavelengths into a fleshy medium and a detector configured to generate at least first and second intensity signals in response to receiving light after absorption by constituents of pulsatile blood flowing within the fleshy medium; a monitor configured to receive said intensity signals, generate digitized signals from said intensity signals at a sampling rate, compute physiological parameter data responsive to said digitized signals, and display one or more of said computed physiological parameter data responsive to said intensity signals, or trend data responsive to trends in said computed physiological data or said intensity signals; and a data storage device integrated with said monitor, said data storage device being configured to record on a removable storage media data at said sampling rate (sampling rate data) and data at a sub-sampling rate (sub-sampling data) using message packets having a format capable of preserving a relationship between the sampling rate data and the sub-sampling rate data, wherein said sampling rate data comprises at least a plethysmograph waveform data and said sub-sampling rate data comprises at least said computed physiological parameter or trend data.
