Abstract

A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

Core Innovation

A first medical device receives a first physiological signal from a physiological sensor and determines a first physiological parameter value of a first physiological parameter associated with a patient. The first medical device outputs, in a first section of a display, the first physiological parameter value together with a corresponding waveform and alarm limits associated with the first physiological parameter, and outputs a second physiological parameter value in a second section without indications of corresponding alarm limits.

In response to a first user input dragging the second physiological parameter value from the second section to the first section, the device causes the second physiological parameter value together with a corresponding waveform of the second physiological parameter to be displayed in the first section adjacent to the first physiological parameter value together with the corresponding waveform of the first physiological parameter. In response to a second user input dragging the corresponding waveform of the second physiological parameter onto the corresponding waveform of the first physiological parameter, the device causes the corresponding waveforms to overlay on one another in a same portion of the display such that both waveforms are visible, continuous, and aligned in time.

The corresponding waveforms comprise a plethysmograph and respiration, and the device determines a level of correlation between the first physiological signal and a second physiological signal associated with the second physiological parameter by determining a correlation between peaks or valleys in the plethysmographic signal and bursts in the respiratory signal. When the level of correlation satisfies a correlation threshold, the first medical device outputs at least one of a graphical indication or an audible alarm.

The broader system context includes a medical monitoring hub/system where physiological parameter data received for a second medical device is routed through a translation module that applies translation rules to generate translated parameter data compatible with a hub and/or auxiliary device for display, including protocol translation such as HL7-to-HL7 format translation and/or protocol translation such as HL7, ISO 11073, and proprietary protocols, with alarm/notification routing from translated messages.

Claims Coverage

The provided content supports two independent claim themes with six inventive features: interactive multi-section physiological display with selective alarm-limit indication, drag-and-drop waveform relocation and overlay, correlation-based alerting, and interoperable translation and alarm routing in a medical monitoring hub/system.

Overall, the claims cover interactive display of first and second physiological parameters, user-driven waveform overlay and time alignment, correlation-based alerting using plethysmographic and respiratory signals, and translation-based interoperability with alarm and notification routing.
