  • Page 10: Initial Device Setup

    Operation Initial Device Setup When you first receive your Aera CT device, the wireless system must be configured to communicate with your receiving software. To achieve this, follow the instructions from your software provider to load the necessary wireless settings onto the provided microSD card. Insert the configured microSD card into the card holder, located in the battery compartment, of the Aera CT.
  • Page 11: User Interface

    Operation User Interface The Aera CT employs a graphical user interface consisting of a color LCD and 5 touch-sensitive keys for configuration and patient hookup procedures. The only touch-sensitive areas of the device are the 5 keys. The LCD is NOT a touch screen. Note: Aggressive attempts to use the LCD as a touch-screen can result in irreparable damage to the LCD.
  • Page 12: Starting A Study

    Operation Starting a Study To begin a new patient study, the receiving software must first be configured. Follow the instructions from your software provider to set all of the relevant parameters and prepare the server for the new patient study. If it is anticipated that the patient hookup procedure will be performed in a location that does not have reliable wireless connectivity, this process should include loading the settings for the study onto the microSD card in the device, according to the instructions from your software provider.
  • Page 13 Operation Starting a Study (continued) Figure 10 Figure 11 This device needs to erase the SD card The device will double check to make sure before it can continue with a new study. that you want to erase all the data. When there is no data on the microSD card, you will be prompted to update the device’s clock.
  • Page 14 Operation Starting a Study (continued) Once the device time has been verified, the Aera CT must load the proper settings for the new study. If the settings were previously loaded onto the microSD card, select the KEEP CURRENT option to continue. This could be used when poor wireless reception is expected.
  • Page 15 Operation Starting a Study (continued) Once the device has successfully downloaded the latest settings, it will automatically prompt you to connect the patient to the device by displaying the selected electrode configuration on the display. It will also silently report the successful settings download action to the server in the background.
  • Page 16 Operation Starting a Study (continued) On the “ECG Quality” screen, the Aera CT will draw the ECG trace from one of its three input channels in real time. Toggle which channel is being drawn by highlighting the LEAD option and pressing SELECT. If necessary, highlight the SCALE option and press SELECT to change the dynamic range of the display.
  • Page 17: Monitoring A Study

    Operation Monitoring a Study Once a study has been started, the Aera CT will silently record and transmit ECG data with no intervention from the patient. The patient can wake the display by briefly pressing the patient event button to view a status screen with instructions on how to mark an event.
  • Page 18 Operation Monitoring a Study (continued) For the duration of the study, the Aera CT will periodically upload files to the receiving server. These event files provide information on the status of the device, (such as battery life, recording state, and electrode connection status), as well as information on detected arrhythmias and patient activated events.
  • Page 19: Ending A Study

    Operation Ending a Study The Aera CT provides 2 automated methods and 2 manual methods for ending a study. When the Aera CT is configured at the beginning of the study, it can be programmed to automatically end the study after a specific length of data has been recorded, or to end the study at a specific date and time.
  • Page 20 Operation Ending a Study (continued) It is also possible to end the study from the device itself using the early-out procedure: 1. Make sure the recording is suspended by disconnecting the patient cable from the device. 2. Simultaneously hold the left key on the keypad while briefly pressing the patient event button to access the “security code screen”.
  • Page 21 Operation Ending a Study (continued) After entering the first 4 digits of the device’s serial number, the Aera CT will prompt you one last time to make sure that you wish to end the study. Select the STOP option to end the study and transmit any remaining pending data to the server.
  • Page 22: Electrode Application

    Operation Electrode Application Employ the following procedure when applying electrodes to a patient and connecting them to the Aera CT: 1. Select electrode sites to match the configured electrode configuration shown in the following figures or as instructed by the physician.
