A multiparameter monitor (MPM) for a patient includes a disposable electrode patch (DEP) comprising a plurality of male snap post electrodes, an optics interface and a thermal/respiratory interface to a skin surface of the patient. The MPM also includes an electronics module and wireless transmitter (EMT) in connection with a plurality of female snap receptors and configured to transmit a signal data based on a connection and a disconnection of the plurality of the female snap receptors to the male snap post electrodes. The MPM additionally includes a reflective pulse oximeter (RPO) separated from a skin surface of the patient based on a thickness of the DEP, the RPO in communication with the wireless transmitter. The MPM further includes a mobile photoplethysmogram processor (PPG) in communication with the wireless transmitter and the optics interface and configured to filter a motion artifact in the PPG.
