Zusammenfassung:	An apparatus for reducing noise in an electrical system includes a first isolation stage for a patient monitoring system that provides a first power transformation and a first isolation barrier to current flow. The patient monitoring system including a portable patient monitoring device, a charging apparatus that charges the portable patient monitoring device and a power supply that provides power to the charging apparatus and the first isolation stage is connected to the power supply. A second isolation stage is electrically connected between the first isolation stage and the charging apparatus. The second isolation stage provides a second power transformation and a second barrier to current flow, the second isolation stage reduces noise in the electrical system caused by stray currents.
