Abstract
A patient monitoring system comprises a data acquisition device that records physiological signals from a patient, the data acquisition device having at least 3 receiving ports, each receiving port configured to connect to a patient connector. The monitoring system further includes a galvanic patient connector that galvanically connects a first receiving port of the patient connector and the patient, and at least a first capacitive patient connector and a second capacitive patient connector. Each capacitive patient connector capacitively couples a respective receiving port of the data acquisition device and the patient.
