摘要： Present embodiments relate to systems, methods, and devices for decomposing a physiological signal of a patient using empirical mode decomposition (EMD). In one embodiment, the EMD algorithm may involve identifying a frequency component, referred to as an intrinsic mode function, in the physiological signal. The physiological signal may be decomposed into one or more intrinsic mode functions through multiple iterations of the EMD algorithm. Each subsequent mode function may have a different frequency component of the original physiological signal input into the EMD algorithm. In some embodiments, each mode function may be further analyzed and/or processed to determine various physiological data corresponding to blood flow in the patient.

The combined sensor (e.g., a forehead sensor) may be used to detect and/or calculate at least one of a pulse blood oxygen saturation level, a regional blood oxygen saturation level, a respiration rate, blood pressure, an electrical physiological signal (EPS), a pulse transit time (PTT), body temperature associated with the subject, a depth of consciousness (DOC) measurement, any other suitable physiological parameter, and any suitable combination thereof. The combined sensor may include a variety of individual sensors, such as electrodes, optical detectors, optical emitters, temperature sensors, and/or other suitable sensors. The sensors may be advantageously positioned in accordance with a number of different geometries. The combined sensor may also be coupled to a monitoring device, which may receive and/or process one or more output signals from the individual sensors to display information about the medical condition of the subject. In addition, several techniques may be employed to prevent or limit interference between the individual sensors and their associated input and/or output signals.

摘要： The present disclosure describes techniques that may provide more accurate estimates of arterial oxygen saturation using pulse oximetry by switching between a wavelength spectrum of at least a first and a second light source so that the arterial oxygen saturation estimates at low (e.g., in the range below 75%), medium (e.g., greater than or equal to 75% and less than or equal to 84%), and high (e.g., greater than 84% range) arterial oxygen saturation values are more accurately calculated. In one embodiment, light emitted from a near 660 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is high. In another embodiment, light emitted from a near 730 nm and a near 900 nm emitter pair may be used when the arterial oxygen saturation range is low. In yet another embodiment, light emitted from both a near 660 nm-900 nm emitter pair and light emitted from a near 730 nm-900 nm emitter pair may be used when the arterial oxygen saturation range is in the middle range. Priming techniques may also be used to reduce or eliminate start up delays of certain oximetry system components.
