1. A processing system for patient medical parameters, comprising:
- a communication interface for acquiring patient parameter data comprising a medically significant signal from a patient monitoring device attached to a patient;
a transform processor for converting said medically significant signal into a plurality of components using a transform;
a filter for filtering said components to exclude components based on criteria to provide filtered components; and
an inverse transform processor for inverse-transforming said filtered components to provide a representation of said signal.

Abstract
A processing system for patient medical parameters includes a communication interface for acquiring patient parameter data comprising a medically significant signal from a patient monitoring device attached to a patient. A transform processor converts the medically significant signal into a plurality of components using a transform. A filter filters the components to exclude components based on criteria to provide filtered components. An inverse transform processor inverse-transforms the filtered components to provide a representation of the medically significant signal.

12. A method for processing raw data streams produced by a biomedical monitoring device, wherein the raw data streams are processed by performing the following:
-
inputting the raw data streams to a telemetry server having processing means capable of dividing each raw data stream into at least a first component and a second component;
forwarding the first component to a storage device capable of storing substantially all data values present in the raw data stream; and
forwarding the second component to a transform processor capable of assigning a relative significance to each data value present in the raw data stream. - View Dependent Claims (13, 14, 15, 16)

17. A method of reducing data transmission and storage requirements in a telemetry processing system used for collecting and displaying a nonstationary event, comprising:
-
collecting substantially all data values present in a signal that characterizes the nonstationary event;
assigning a relative contribution value to each data value present in the signal;
excluding each data value assigned a relative contribution value having a relatively small effect on the signal, thereby creating a set of excluded data values;
including each data value assigned a relative contribution value having a relatively large effect on the signal, thereby creating a set of included data values; and
constructing an approximation of the signal using the set of included data values. - View Dependent Claims (18, 19, 20)
