Abstract
Description
Technical Field
[0001] This disclosure generally relates to automated and semi-automated external defibrillators. In particular, this disclosure relates to the configuration of external defibrillators based on their geographical location. Background Technology
[0002] Electrochemical activity within the human heart normally causes myocardial fibers to contract and relax in a synchronized manner, resulting in the efficient pumping of blood from the ventricles to the body's vital organs. Sudden cardiac death is usually caused by ventricular fibrillation (VF), in which abnormal electrical activity within the heart causes individual muscle fibers to contract asynchronously and chaotically. The only effective treatment for VF is electrical defibrillation, in which an electric shock is applied to the heart to allow the heart's electrochemical system itself to resynchronize. Once organized electrical activity is restored, synchronized muscle contractions usually follow, leading to the restoration of a heart rhythm.
[0003] Figure 1 This is an example of the prior art of a defibrillator 10 used by user 12 to resuscitate patient 14 who has suffered cardiac arrest. In cardiac arrest (also known as cardiac arrest), a patient's normal heart rhythm is interrupted in a life-threatening manner, usually in the form of ventricular fibrillation (VF) or ventricular tachycardia (VT), which is not accompanied by a palpable pulse (shockable VT). In VF, normal rhythmic ventricular contractions are replaced by rapid, irregular spasms, which result in ineffective and severely reduced pumping of blood by the heart. If a normal rhythm is not restored within a timeframe generally understood to be approximately 8 to 10 minutes, patient 14 will die. Conversely, the faster defibrillation can be applied after a VF episode, the greater the chance of patient 14 surviving the event.
[0004] The defibrillator 10 may be in the form of an automated external defibrillator (AED), which can be operated by users with a wide range of skill levels, from first responders to physicians, including defibrillation-trained emergency medical technicians (EMT-Ds), police officers, flight attendants, security personnel, occupational health nurses, and firefighters. AEDs can also be used in areas of hospitals where access to ACLS (Advanced Cardiac Life Support) trained personnel is not readily available.
[0005] Currently, AEDs typically come with accompanying software that medical supervisors or other responsible parties use to select configuration parameters of their choosing (e.g., compression rate, ventilation ratio, pediatric age threshold). This disclosure relates to improving the selection of configuration parameters for automated systems. Summary of the Invention
[0006] This disclosure provides an automated method for efficiently configuring an AED based on the geographic location where the AED will be used.
[0007] This disclosure can be embodied in (1) an automatically configurable external defibrillation system and (2) an automatically configurable external defibrillation method.
[0008] Various exemplary embodiments of the automated configurable external defibrillator system disclosed herein employ a configurable external defibrillator and a mobile rescue device. When communicating with the configurable external defibrillator, the mobile rescue device automatically retrieves parameters / guidelines for configuring the defibrillator's defibrillation and / or resuscitation modules based on the geographic location of at least one of the external defibrillator and the mobile rescue device itself, and the configurable external defibrillator automatically configures its defibrillation and / or resuscitation modules based on the parameters / guidelines retrieved by the mobile rescue device.
[0009] Various exemplary implementations of the automated configurable external defibrillator method involve (1) establishing communication between a configurable external defibrillator and a mobile rescue device, (2) the mobile rescue device automatically retrieving parameters / guidelines for configuring at least one of the defibrillation module and resuscitation module of the configurable external defibrillator based on the geographic location of at least one of the configurable external defibrillator and the mobile rescue device, and (3) the configurable external defibrillator automatically configuring at least one of the defibrillation module and resuscitation module of the external defibrillator based on the parameters / guidelines retrieved by the mobile rescue device.
[0010] The foregoing exemplary and other embodiments of this disclosure, as well as the various structures and advantages of this disclosure, will become more apparent to those skilled in the art from the following detailed description of various embodiments read in conjunction with the accompanying drawings. The detailed description and drawings are illustrative only and not limiting of this disclosure, the scope of which is defined by the appended claims and their equivalents.

Detailed Implementation
[0012] This disclosure provides an automated method for efficiently configuring an AED based on the geographic location where the AED will be used.
[0013] For the purposes of describing and claiming protection of this disclosure, the terminology of this disclosure field used herein broadly encompasses the definitions of such terms as are known in this disclosure field.
[0014] For ease of understanding this disclosure, Figure 2-6 The following description teaches exemplary embodiments according to this disclosure. Figure 2-6 Based on the description, those skilled in the art will understand how to apply this disclosure to make and use other embodiments according to this disclosure.
[0015] Figure 2 As an example of the configurable external defibrillator (CED) 10a according to this disclosure, it may be a configurable automated external defibrillator or a configurable semi-automated external defibrillator. The user interface of the CED 10a includes an on / off button 34. A status indicator 36 indicates that the CED 10a is ready for use. A display 32, typically implemented using LCD technology, provides visual cues to the user 12 and can be used to graphically display ECG waveforms and CPR prompts. A speaker 38 provides audio cues to the user 12, such as by voice or tone. The shock button 30 is pressed by the user 12 in response to prompts from the CED 10a, such as illuminating the shock button 30 and generating an audio cue. Electrode pairs 16 are inserted into sockets 17 to connect the patient 14 to the CED 10a.
[0016] Figure 3 This is an example of an exemplary embodiment of CED 10a according to the present disclosure. An electrode pair 16 for attachment to a patient 14 is connected to an ECG front end 18 and further connected to an HV switch 28. The ECG front end 18 provides detection, filtering, and digitization of the ECG signal from the patient 14. The ECG signal is then provided to a controller 26, which runs a shock advisory algorithm capable of detecting ventricular fibrillation (VF) or other shockable rhythms susceptible to electrotherapy.
[0017] After the controller 26 has detected a VF or other shockable rhythm, the user 12 presses the shock button 30 to initiate the delivery of a defibrillation pulse through the electrode pair 16. The battery 24 typically powers the CED 10a, and specifically powers the high-voltage charger 22 that charges the capacitors in the energy storage circuit 20. A typical battery voltage is 12 volts or lower, while the energy storage circuit 20 can be charged to 1500 volts or higher. A charging voltage control signal from the controller 26 determines the charging voltage in the energy storage circuit 20. The shock button 30, display 32, speaker 38, and status indicator 36 together form the user interface 42.
[0018] Energy storage circuit 20 is connected to HV switch 28, which operates to deliver defibrillation pulses to patient 14 across electrode pair 16 in response to desired polarity and duration of a switch control signal from controller 26. In a preferred embodiment, HV switch 28 is preferably constructed using an H-bridge to deliver biphasic defibrillation pulses, but can be readily adapted to deliver monophasic or multiphasic defibrillation pulses while still achieving the benefits of this disclosure.
