Abstract
An infusion apparatus includes a pump powered by a source of battery power and capable of operating in a plurality of infusion modes and operating in a power savings mode. The infusion apparatus further includes sensors which sense various conditions of the pump. A controller is programmed to periodically operate in a power-savings mode of operation and also selectively causes each sensor to be connected to the battery power only when the sensor is to detect a condition, thus further conserving battery power.
