Description: Semiautomatic defibrillator (PAD)
Information:

Device operation FRED easy® is a battery-operated semiautomatic Defibrillator that provides biphasic defibrillation pulses. Defibrillation takes place by means of single-use adhesive Electrodes through which the ECG signals required for the analysis are also collected. Adhesive Electrodes are available for children and adults. The device recognises the type of electrode applied and selects the defibrillation energy values accordingly. The user is provided with written and audio instructions (display and loudspeaker) relating to the use of the device. The power is supplied by plug-in disposable lithium batteries. Their capacity is sufficient for - 200 shocks at the maximum power rating or - use of the monitor for seven hours (cyclical, 30 minutes on, 30 minutes off) or - 5 years standing by. As soon as a battery is put in place in the FRED easy® device, it runs a self test to check the status of the device and battery. If the device does not find any fault, the green indicator begins to flash to show that it is ready to operate and the display disappears. Likewise, the device runs a self test each time it is switched on. If, during the test, the device finds an error: - it issues an audio alarm, - the green indicator does not flash The alarm signal rings till the battery is completely discharged. Key error message is displayed. is used to repeat the self test and the Also, the device runs a self test after every seven days. The test is announced by a beep. If, during the test, the device finds an error: - it issues an audio alarm, - the green indicator does not flash If you press key the corresponding error message is displayed. In that case, you must replace the battery and repeat the test. Depending on the test result, the error message will disappear or another message will be displayed.
