elective replacement indicator
A device status indicating battery depletion has reached the point where replacement should be scheduled within several months.
Full Definition
The elective replacement indicator (ERI) is a programmed alert that activates when a cardiac device's battery voltage drops to a predetermined level, typically indicating 3-6 months of remaining device longevity. When ERI is reached, the device continues to function normally but enters a modified operating mode to conserve energy. Patients should be scheduled for device replacement within the recommended timeframe to avoid progression to end-of-service status, where device functionality becomes limited. ERI timing varies by manufacturer and device type.
Usage
Usage note: Can be abbreviated as ERI after first use in clinical documentation.
