1. An active pulse sensor in communication with a monitor, the active pulse sensor comprising:

  • an emitter that generates optical radiation having a plurality of wavelengths and transmits the optical radiation into a tissue site;

    a detector that generates a sensor signal responsive to the intensity of the optical radiation after attenuation by the pulsatile blood flow within the tissue site;

    a motor that vibrates when energized in response to an activation signal; and

    a tape means that is configured to removably attach the emitter, the detector and the motor to the tissue site so that vibration from the motor induces pulsatile blood flow within the tissue site when energized,wherein the sensor signal is communicated to the monitor, and the monitor is configured to;

    determine a signal quality of the sensor signal indicative of pulsatile blood flow;

    provide, based on the determined signal quality, the activation signal to the motor so as to induce pulsatile blood flow;

    receive the sensor signal while the activation signal is provided to the motor; and

    determine a physiological measurement using the sensor signal received while the activation signal is provided to the motor.
