Optimizing physiologic monitoring based on available but variable signal quality

摘要

When transmitting patient data over a hospital network, data types are prioritized into a data type hierarchy (26) that is employed to rank data types in order of criticality for transmission during periods of diminished signal quality. As signal quality decreases, less critical data types are omitted from transmission and stored to a gap data buffer for later transmission. As signal quality recovers, the less critical data types are restored to current data transmissions. Once all data types are restored during current transmission, previously omitted gap data is transmitted to fill in the gaps in a receiving device such as a network server to ensure that a complete data set is provided to the network and/or other devices coupled thereto.

1. A network communication optimization system, including:
a transceiver that transmits and receives data over a network; a signal quality analyzer that detects network congestion and latency as a function of actual data delivery and application-based latency measurement; a transmission controller that selectively reduces current data types to be transmitted by the transceiver during periods of diminished signal quality according to a predetermined data type hierarchy; a buffer that stores gap data omitted during reduced data transmission; wherein the transmission controller suspends transmission of buffered gap data before reducing current data transmission in response to detected network congestion or latency; wherein the data type hierarchy includes, in order of priority from highest to lowest where lower priority data types are omitted from transmission before higher priority data types, the following groups of data types: alert data; one or more of: alert overview data and down-sampled waveform data; and
overview data;waveform data;parameter data and event data; andtrend upload data, local cache data, and document upload data.
