Telemedicine report
Regular evaluations over time (MOL 1 and MOL 2) of the battery status by telemedicine. BOL = beginning of life, MOL1 = midlife 1, MOL 2 = midlife 2.
An alert was delivered (RED status) when the elective replacement indicator (ERI) was reached, which can be caused by 1) a battery voltage below the threshold value (for this defibrillator model = 5.7 V), 2) a measurement of the current continuously below the threshold, indicated by an energy gauge posted at 0%, or 3) charge time of the capacitors >20 sec.

Telemedicine optimizes the management of the devices’ end of life. Before telemedicine became available, when the indicators indicated that the end of battery life was approaching, the frequency of follow ups was increased along with the anxiety of some patients. Teleconsultations enable a follow-up of the battery depletion without increasing the number of visits, which offers several advantages, including
