First Claim
Patent Images
1. A system for determining a respiratory rate, the system comprising:
- a wireless sensor device that includes at least one electrode, a processor, a transmitter and a memory device coupled to the processor, the memory device stores executable instructions that, when executed by the processor, causes the processor to;
measure an electrocardiogram (ECG) segment via the at least one electrode;
decompose the ECG segment into a plurality of Intrinsic Mode Functions (IMFs), wherein the ECG segment is decomposed into the plurality of IMFs using Ensemble Empirical Mode Decomposition (EEMD);
evaluate the plurality of IMFs by choosing one of the plurality of IMFs that contributes a maximal percentage of a total respiratory band power of the plurality of IMFs;
calculate the respiratory rate using the one of the plurality of IMFs and a domain detection;
store the calculated respiratory rate in the memory device; and
transmit the stored respiratory rate at a periodic rate, thereby providing continuous remote monitoring of the calculated respiratory rate.

Abstract
A method and system for determining a respiratory rate of a user using an electrocardiogram (ECG) segment of the user are disclosed. The method comprises decomposing the ECG segment into a plurality of functions and evaluating the plurality of functions to choose one of the plurality of functions based on a respiratory band power. The method includes determining the respiratory rate using the one of the plurality of functions and a domain detection.
