Abstract
Disclosed is a system that includes both an Airway and Ventilation device (AV) and an Automated External Defibrillator (AED) device. The system is provided with components for assisting only minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias. The system includes one or both of a mask for applying non-invasive ventilation and a ventilation tube for applying invasive ventilation.
Core Innovation
The invention relates to an emergency medical system configured to assist minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias. The system integrates an Airway and Ventilation device (AV) and an Automated External Defibrillator (AED) and includes a user interface for providing audible or visual instructions to an operator. The system also includes a wireless communication link to a remotely located emergency or medical center and a data management unit adapted to operate the system, provide instructions to the operator, and record ECG and vital signs (VS) data.
The AV device comprises a non-invasive ventilation mask and/or an invasive ventilation tube as inhalation devices, a CO2 sensor configured to measure end tidal CO2 (ETCO2) in exhalations of a patient, sensors adapted to monitor vital signs, and a pressurized oxygen source configured to provide a flow of oxygen via the inhalation device and airway. The pressurized oxygen source is configured to adjust the oxygen flow on the basis of the monitored vital signs, and the system evaluates ventilation using ETCO2 measured in each chest compression applied by the operator to the patient.
The AED device comprises one or more ECG detectors configured to be attached to the chest of the patient to monitor ECG and apply electrical shock via one or more chest pads. The data management unit processor and dedicated software determine when to apply electric shock according to evaluation of the state of ventilation, where the state of ventilation is evaluated according to the ETCO2 measured in each chest compression. The system thereby links respiratory ventilation assessment to the timing of AED shock delivery to guide operation in the emergency setting.
Claims Coverage
The provided independent claim material covers 2 inventive features for a combined emergency response system. The main inventive control concept is timing AED electrical shock based on ventilation state evaluated from ETCO2 measured in each chest compression, together with integrated AV components, ECG detection, operator instructions, and wireless communication.
Ventilation-state-guided shock timing using compression ETCO2
The processor and dedicated software determine when to apply electric shock according to evaluation of the state of ventilation, wherein the state of ventilation is evaluated according to the ETCO2 measured in each chest compression applied by the operator to the patient.
Integrated AV and AED system for minimally trained emergency operation
An emergency system configured to assist minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias, comprising an Airway and Ventilation device (AV) and an Automated External Defibrillator (AED), together with a user interface, a wireless communication link, and a data management unit adapted to provide instructions and record ECG and VS data.
The claim coverage centers on combining an AV device with CO2/ETCO2 and vital-sign monitoring with an AED having ECG detectors and chest pads, and using ETCO2 measured in each chest compression to evaluate ventilation state and determine when to apply electric shock. The system further includes operator instructions, wireless communication to a remotely located emergency or medical center, and recording of ECG and VS data.
