Abstract
A motion insensitive pulse detector for detecting a patient's pulse includes an exciter adapted to be positioned over a blood vessel of the patient and configured to induce a transmitted exciter waveform into the patient. A noninvasive sensor is adapted to be positioned over the blood vessel and configured to sense a hemoparameter and to generate a noninvasive sensor signal representative of the hemoparameter containing a component of a received exciter waveform. A processor is coupled to the noninvasive sensor and configured to process the noninvasive sensor signal to determine the patient's pulse. Advantages of the invention include the ability to detect a patient's pulse even when the patient is moving or being moved by medical personnel.
