    Abstract: A method for measuring blood pressure of a patient continuously and non-invasively comprises measuring a first pressure signal being proportional to arterial blood pressure of the patient at a first location by a first pressure sensor (P1). In addition ambient pressure is measured by a third ambient pressure sensor (P3). Furthermore the method comprises subtracting the signal derived from the third ambient pressure sensor from the signal derived from the first pressure sensor to compensate for alterations induced by alterations in measurement point altitude and atmospheric pressure changes thereby providing a signal representing relative systemic arterial blood pressure of the patient

In a described embodiment, the method 100 includes obtaining a PPG(red) signal and a PPG(IR) signal at steps 102 and 104, and pairing the PPG(red) and PPG(IR) signals at step 106 in which an amplitude of each cardiac rhythm cycle of the first signal is aligned to an amplitude of a respective cardiac rhythm cycle of the second signal to form a plurality of paired windows. At step 108, the method further includes, for each paired window, calculating values of a ratio R from the paired first and second signals and based on the calculated R values, binning the calculated R values into predetermined frequency bins at step 110.

    Abstract: Apparatuses and methods (including methods of using such apparatuses) for de-noising electrocardiograms (ECGs) by manually or automatically adjusting the amount of filtering of an ECG signal. For example, real-time ECG signals may be filtered by combining in a weighted fashion an unfiltered portion of an ECG (or a filtered portion of the same ECG) with the same portion of the ECG that has been filtered. The weighting may be adjusted manually and/or automatically. Also described herein are methods for real-time filtering of ECG signals using a combination of filtering techniques including filtering to correct baseline wander, Savitzky-Golay denoising, and threshold smoothing. Multiple filtering techniques may be combined in a weighed manner to provide signal de-noising.
