Abstract: A device operable to calculate a physiological parameter characteristic of a health condition of a human subject includes a finger cuff that is wearable on the subject's finger and operable to measure the patient's peripheral blood pressure waveform. A memory unit stores the measured peripheral blood pressure waveform, and an adjustable pressure transfer function, which includes at least one adjustable characteristic. The patient's cardiac output is estimated based on the stored measured peripheral blood pressure waveform, and the pressure transfer function is then adjusted based on that estimated cardiac output. The subject's aortic blood pressure waveform is then reconstructed from the stored peripheral blood pressure waveform and the adjusted pressure transfer function. A computing unit then calculates the physiological parameter from the reconstructed aortic blood pressure waveform.

Abstract: The invention relates to method for reconstructing an aortic blood pressure waveform of a person from a peripheral blood pressure waveform of the person comprising the steps of determining at least one pre-selected parameter of the peripheral blood pressure waveform, reconstructing the aortic blood pressure waveform from the peripheral blood pressure waveform using a pressure transfer function having at least one adjustable characteristics, wherein said adjustable characteristics is determined using the at least one pre-selected parameter of the peripheral blood pressure waveform. The invention further relates to a device for reconstructing an aortic blood pressure waveform from a peripheral blood pressure waveform and a computer program product.
