The state machine operates the AED trainer in an efficient and effective manner to train students to correctly perform rescue procedures on patients suffering from Sudden Cardiac Arrest. ## Claims ### Claim 1 A method for training a student to perform an emergency rescue procedure, comprising: configuring a configuration option of an automatic external defibrillator (AED) trainer using a user interface of the AED trainer, wherein the AED trainer comprises a hardware platform and state machine which together simulate the appearance and operations of a target AED, wherein the user interface is provided on a display of the AED trainer, and wherein the display is located underneath an electrode tray of the AED trainer; providing the AED trainer to the student; and using the AED trainer to instruct the student, by way of synthesized voice prompts that are based on the configuration option and output by a speaker of the AED trainer, in performing a simulated rescue procedure on a manikin, wherein the simulated rescue procedure includes applying simulated cardiopulmonary resuscitation (CPR) and shocks to the manikin. ### Claim 2 (depends on 1) The method of claim 1, wherein configuring the configuration option comprises providing a user interface element enabling selection of a language for the voice prompts. ### Claim 3 (depends on 2) The method of claim 2, wherein configuring the configuration option comprises providing a user interface element enabling selection of a primary and a secondary language for the voice prompts. ### Claim 4 (depends on 1) The method of claim 1, wherein configuring the configuration option comprises providing a user interface element enabling selection an adult mode and a child mode of operation. ### Claim 5 (depends on 1) The method of claim 1, further comprising providing guidance for CPR in the form of audible prompts. ### Claim 6 (depends on 1) The method of claim 1, further comprising performing simulated analysis during periods of simulated charging and chest compressions. ### Claim 7 (depends on 1) The method of claim 1, further comprising providing voice prompts to encourage the student to perform simulated checks for breathing, airway obstructions, and blood circulation. ### Claim 8 (depends on 1) The method of claim 1, further comprising pausing the synthesized voice prompts upon detecting that the student has pressed a power button of the AED trainer for less than a predetermined length of time. ### Claim 9 (depends on 1) The method of claim 1, further comprising detecting simulated CPR performance, and providing real time synthesized voice feedback if no CPR is detected or if incorrect CPR performance is detected, including incorrect rate, depth and recoil. ### Claim 10 (depends on 1) The method of claim 1, wherein the AED trainer simulates a shorter CPR pause time when a shock is advised, and the AED trainer simulates no CPR pause time for analysis when no shock is advised. ### Claim 11 (depends on 2) The method of claim 2, further comprising providing a user interface element enabling selection of display text. ### Claim 12 (depends on 11) The method of claim 11, wherein the AED trainer further comprises buttons below the display, and wherein the method further comprises navigation of the display text using a cursor displayed as a negative color image on a current text field, wherein the buttons allow the user to scroll the cursor through displayed settings to reach a desired feature. ### Claim 13 (depends on 1) The method of claim 1, further comprising providing a user interface element allowing a user to configure and view the following options: current software status, battery status, Bluetooth connectivity, and Bluetooth serial number. ### Claim 14 (depends on 1) The method of claim 1, further comprising detecting ambient noise levels and automatically adjusting the volume of synthesized voice prompts in response to detected ambient noise levels. ### Claim 15 (depends on 1) The method of claim 1, further comprising detecting that no CPR is being performed and providing synthesized voice prompts to instruct the student to perform CPR and providing CPR feedback to the student. ### Claim 16 (depends on 1) The method of claim 1, wherein the AED training further comprises at least one wireless radio transceiver, and wherein the method further comprises providing real-time data outputs via the wireless radio transceiver. ### Claim 17 (depends on 16) The method of claim 16, wherein the data outputs include static data including AED trainer serial number and software version, as well as data concerning real-time actions of the AED trainer including pausing, turning on, and moving into analysis. ### Claim 18 (depends on 1) The method of claim 1, further comprising demonstration of wireless control of an AED communicating with a smartphone app and a cloud-based network. ### Claim 19 (depends on 18) The method of claim 18, further comprising controlling the AED trainer using two-way communication with the smartphone app. ### Claim 20 (depends on 1) The method of claim 1, wherein the AED trainer further comprises a universal serial bus (USB) port, and wherein the method further comprises updating software in the AED training through the USB port.
