A Web-based Wavelet Application to Reduce One Dimensional Physiological Data with Infrequent Short Duration Event for Remote Display

Most current patient monitors can connect to a local area network. This has resulted in an exponential increase in the data volume to be stored, transmitted and viewed. A novel Web-based wavelet application to perform reliable display of long-term one dimensional (ID) physiological data with infrequent short duration events on the client through lossless transfer of only the useful data is proposed. Our solution, in which only the scaling coefficients are transmitted, is able to analyze, transfer and display data efficiently. More importantly, it adapts data to the display width of the remote monitor screen by adjusting the resolution through decomposition, so that segments of physiological interest can be extracted and transmitted at the required resolution. This not only accelerates data transfer but also provides a less cluttered display. This also contributes to an important aspect of telemedicine applications that has received little attention, that is the integrity and reliability of data interpretation and diagnosis
