Claim 8:
9. A physiological monitoring method for monitoring a physiological parameter of a patient, said physiological monitoring method comprising:
transmitting, by an optical sensor, optical radiation into a tissue site of the patient, said optical sensor including one or more components, said one or more components comprising at least one emitter and at least one detector;
detecting, by the optical sensor, a plethysmograph waveform responsive to attenuation of the transmitted optical radiation by the tissue site,
controlling a first motor to vary a first 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;
controlling a second motor separated from the first motor by an isolator to vary a second coupling between at least other of the some of the one or more components of the optical sensor and the skin;
detecting a plurality of plethysmograph waveform corresponding to varying coupling of the one or more components of the optical sensor and the skin; and
monitoring a physiological parameter responsive to the detected plurality of plethysmograph waveforms.
