Incorrect key presses may cause Moog Medical's Zevex Infinity enteral feeding pumps to appear to be infusing even though an occlusion exists.

If users of Moog Medical's Zevex Infinity series feeding pumps--the EnteraLite Infinity and the Infinity Orange--use an incorrect key-press sequence while attempting to address a downstream occlusion alarm, the pump's display may mimic normal operation even though the unit is not delivering feeding solution. Although Moog states that it has not received any reports of injury related to these devices, failure to deliver nutrition may result in hypoglycemia, which can have severe outcomes for patients who have difficulty maintaining their blood sugar levels. Users of these pumps should become familiar with this issue and with the guidance offered in the products' operator manuals. This behavior is similar to that of the Nutricia Flocare Infinity series enteral feeding pumps--also produced by Moog Medical--which we described in the May 2011 issue of Health Devices.
