  • Publication number: 20220007976
    Abstract: A regional oximetry system has a display and at least one processor causing a plurality of views to be displayed on the display, each configured to occupy at least a portion of the display. The views are adapted to present data responsive to at least one physiological signal. A first sensor port is configured to receive at least a first physiological signal representative of a regional tissue oxygenation level, and a second sensor port is configured to receive at least a second physiological signal representative of an arterial oxygen saturation level. One view presents a first trend graph of the first physiological signal and a second trend graph of the second physiological signal. An area between the first trend graph and the second trend graph can include a differential analysis of regional-to-central oxygen saturation.

  • Patent number: 11219391
    Abstract: A pulse oximeter may reduce power consumption in the absence of overriding conditions. Various sampling mechanisms may be used individually or in combination. Various parameters may be monitored to trigger or override a reduced power consumption state. In this manner, a pulse oximeter can lower power consumption without sacrificing performance during, for example, high noise conditions or oxygen desaturations.

  • Publication number: 20210386327
    Abstract: A patient monitoring system to help manage a patient that is at risk of falling is disclosed. The system includes a patient-worn wireless sensor that can be affixed to the patient's back that senses the patient's motion and wirelessly transmits information indicative of the sensed motion to a patient monitor. The patient monitor receives, stores, and processes the transmitted information to determine whether the patient has fallen or is about to fall. Upon such detection, the system can notify the patient's caretakers that the patient has fallen or is about to fall and therefore, is in need of immediate attention.

  • Publication number: 20210378566
    Abstract: Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.

  • Patent number: 11191485
    Abstract: A physiological monitor has a sensor port configured to attach and communicate with a sensor. A processor board is in communications with the sensor port and has a board digital signal processor (DSP). Firmware residing on the processor board is executable by the board DSP so as to calculate physiological parameters in response to a sensor signal received from the sensor. Upgrade tools are individually attachable to the sensor port in lieu of the sensor so as to designate to the processor board which of the physiological parameters, if any, to calculate when the sensor is attached to the sensor port.

  • Patent number: 11191484
    Abstract: Various sensor tapes can improve securing of a non-invasive optical sensor to a surface of a medium for taking noninvasive measurement of characteristics of the medium. The sensor tape can taper from a wide end to a narrow end. The sensor tape can transition from a wide portion to a narrow portion in a step-like change or slope. The sensor tape can have staggered portions. The various tapes can be used with an L-shaped sensor. The various tapes can increase contact surface between the surface of the medium and an adhesive side of the tape so as to reduce motion-induced noise.

  • Publication number: 20210369231
    Abstract: A physiological acoustic monitoring system receives physiological data from an acoustic sensor, down-samples the data to generate raw audio of breathing sounds and compresses the raw audio. The acoustic monitoring system has an acoustic sensor signal responsive to tracheal sounds in a person. An A/D converter is responsive to the sensor signal so as to generate breathing sound data. A decimation filter and mixer down-samples the breathing sound data to raw audio data. A coder/compressor generates compressed audio data from the raw audio data. A decoder/decompressor decodes and decompresses the compressed audio data into decompressed audio data. The decompressed audio data is utilized to generate respiration-related parameters in real-time. The compressed audio data is stored and retrieved so as to generate respiration-related parameters in non-real-time. The real-time and non-real-time parameters are compared to verify matching results across multiple monitors.

  • Patent number: 11185262
    Abstract: A device for obtaining physiological information including plethysmographs of a medical patient and detecting a condition of pneumonia. The portable pneumonia screening device may include one or more sensors configured to obtain physiological information. The pneumonia screener may provide for methods of selecting and interfaces to assist selecting a patient's age group. The screener may match a selected age group from a set of programmed threshold level of oxygen saturation, respiratory, pulse rate, or other physiological parameters to assist pneumonia diagnosis. The pneumonia screener may provide one or more visual and/or audio stimuli, such as an animation, sound or music. The visual and/or audio stimuli may indicate initialization, diagnostic in progress, completion, or other events or progress of events. In some embodiments, the visual and/or auditory stimuli may be used to soothe or intrigue the patient such that patient agitation is reduced during the screening process.

  • Patent number: 11179111
    Abstract: Automated critical congenital heart defect (“CCHD”) screening systems and processes are described. A caregiver may be guided to use a single or dual sensor pulse oximeter to obtain pre- and post-ductal blood oxygenation measurements. A delta of the measurements indicates the possible existence or nonexistence of a CCHD. Errors in the measurements are reduced by a configurable measurement confidence threshold based on, for example, a perfusion index. Measurement data may be stored and retrieved from a remote data processing center for repeated screenings.
