    Abstract: Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.

    Abstract: A malaria diagnosis and/or treatment apparatus can include an optical source and an acoustic detector in a single probe (sensor). The optical source can provide optical energy configured to produce transient vapor nanobubbles around malaria-specific nanoparticles, such as hemozoin in skin, blood and other tissues infected with malaria, but not in uninfected tissues. The acoustic detector can detect pressure pulses generated by the transient vapor nanobubbles. A malaria diagnosis and/or screening process can be based on using several metrics of the detector signal output, which include the time and amplitude parameters of such signal. This metrics characterize both active and residual forms of malaria disease and can be used in the clinical diagnostics of malaria and in mass screening of the malaria transmission.

    Abstract: A method and an apparatus to analyze two measured signals that are modeled as containing desired and undesired portions such as noise, FM and AM modulation. Coefficients relate the two signals according to a model defined in accordance with the present invention. In one embodiment, a transformation is used to evaluate a ratio of the two measured signals in order to find appropriate coefficients. The measured signals are then fed into a signal scrubber which uses the coefficients to remove the unwanted portions. The signal scrubbing is performed in either the time domain or in the frequency domain. The method and apparatus are particularly advantageous to blood oximetry and pulserate measurements. In another embodiment, an estimate of the pulserate is obtained by applying a set of rules to a spectral transform of the scrubbed signal. In another embodiment, an estimate of the pulserate is obtained by transforming the scrubbed signal from a first spectral domain into a second spectral domain. The pulserate is found by identifying the largest spectral peak in the second spectral domain.
