An electrode padset and a method of using the electrode padset are disclosed herein. The electrode padset is a single unit, consisting of multiple patient-contacting conductive pads arranged on a single piece of material. The padset is comprised of a plurality of conductive pads, at least one conductive pad adapted to emit an electrical signal and at least one other conductive pad adapted to receive an electrical signal, and an electrically conductive material coupling the conductive pads.

Spacing of electrodes for bioimpedance measurements

Disclosed is a bioimpedance measurement system: A stabilized high frequency current generator is connected to PadSet electrodes via a Patient Cable. Electrodes are connected to an adaptive circuit that conditions the resulting voltage signal and converts it to digital form. Firmware performs signal acquisition and relays data to the device.

Methods and systems of displaying flow-volume loops of a patient and variability of the flow-volume loops across measured breaths are disclosed. The methods comprise obtaining a physiological dataset of the patient on a data acquisition device, applying a smoothing and curve fitting algorithm to the physiological dataset on a processing device to obtain real-time volume and flow data at a plurality of time instances, applying a visualization algorithm on the processing device to the volume and flow data to create a series of flow-volume loops based on the volume and flow data, and outputting a plot of the flow-volume loops on a display device to aid evaluation or diagnosis of the patient.

Devices and methods of calculating and displaying continuously monitored tidal breathing flow-volume loops (TBFVL) obtained by non-invasive impedance-based respiratory volume monitoring

Disclosed is a system that includes a sensor for acquiring a physiological bioelectrical impedance signal from a patient functionally connected to the computing device. The computing device preferably analyzes the physiological bioelectrical impedance signal and provides outputs an assessment of minute ventilation of the patient based on the analyzed bioelectrical impedance signal. Preferably, the system monitors the signal over time, provides a control signal to an IV pump that instructs the IV Pump to automatically adjust medication levels by automatically lowering medication levels when respiration levels fall or completely stopping flow of the medication.

Evaluation of respiratory volume monitoring (RVM) to detect respiratory compromise in advance of pulse oximetry and eliminate false desaturation alarms

An early warning scoring system and method include a computing device, a plurality of sensors for acquiring physiological signals from a patient, wherein the sensors are functionally connected to the computing device, and at least one alarm adapted to output an alert upon an early warning score (EWS) exceeding a predetermined level. The computing device receives the physiological signals from the sensors, analyzes the physiological signals, and based on the analyzed signals, calculates the early warning score, and compares to the early warning score to predetermined limits and, if the score is outside the limits, triggers an alarm or actuates or modifies a treatment or medical intervention.

The invention is directed to a hyperspectral/multispectral system referred to as the OxyVu-1 system. The hyperspectral imaging technology performs spectral analysis at each point in a two-dimensional scanned area producing an image displaying information derived from the analysis. For the OxyVu-1 system, the spectral analytical methods determined in superficial tissues approximate values of oxygen saturation (HT-Sat), oxyhemoglobin levels (HT-Oxy), and deoxyhemoglobin levels (HT-Deoxy). The OxyVu-1 system displays the tissue oxygenation in a two-dimensional, color-coded image. The system contains a system console, a cart, system electronics, CPU, monitor, keyboard, pointing device and printer. The hyperspectral instrument head with support arm contains broadband illuminator, camera and spectral filter for collecting hyperspectral imaging cube. The single use OxyVu Check Pads and Targets are used to perform an instrument check prior to patient measurements. The OxyVu Target is placed within the intended field of view and is used as a fiduciary mark for image registration and for focusing.
