Abstract
Apparatus, systems, and methods for powering an electric device coupled to a patient to reduce transients on patient monitoring devices are provided herein. In some embodiments, an apparatus for reducing transient electrical events on a patient monitoring device may include a device that can be powered on or off to cause current flow through a load of the device and which has a line out that is capacitively coupled to a patient during use; and a control circuit to control a periodic coupling of first and second voltage sources to the load out of phase at a predetermined carrier frequency to provide continuous current flow through the load in alternating directions, and to control the periodic coupling of first and second voltage sources to the load in phase at a predetermined carrier frequency to provide no current flow through the load.
