Claim 0:
1. A physiological monitoring system configured to monitor a physiological parameter of a patient, said physiological monitoring system comprising:
an optical sensor including one or more components, said one or more components comprising at least one emitter configured to transmit optical radiation into a tissue site of the patient and at least one detector configured to detect a plethysmograph waveform responsive to attenuation of the transmitted optical radiation by the tissue site,
a first motor and a second motor separated from the first motor by an isolator, wherein the first motor and the second motor is configured to vary a respective coupling between at least some of the one or more components of the optical sensor and a skin over the tissue site of the patient; and
one or more hardware processors configured to:
control the motor to vary the coupling;
detect a plurality of plethysmograph waveform corresponding to varying coupling of the one or more components of the optical sensor and the skin; and
monitor a physiological parameter responsive to the detected plurality of plethysmograph waveforms.
