Adherent device for sleep disordered breathing
First Claim
1. A method of monitoring a sleep apnea and/or hypopnea of a patient, the method comprising:
- adhering an adhesive patch to a skin of the patient to couple at least one electrode to the skin of the patient, wherein the adhesive patch supports the at least one electrode, impedance circuitry, a processor, and wireless communication circuitry;
measuring an impedance signal of the patient with the impedance circuitry coupled to the at least one electrode;
processing the impedance signal with the processor to determine a respiration rate;
processing the impedance signal with the processor to determine extracellular fluid of the patient, sufficient to monitor hydration status, wherein the extracellular fluid is determined using impedance measurements with a frequency from about 0.5 kHz to about 20 kHz;
communicating via the wireless communication circuitry the respiration rate and the hydration status to a remote monitoring center;
detecting at the remote monitoring center the sleep apnea and/or hypopnea of the patient in response to the communicated respiration rate;
determining a decompensation risk at the remote monitoring center based on the detected sleep apnea and/or hypopnea and the hydration status.

Abstract
An adherent device is configured to adhere to the skin of the patient with an adherent patch, for example breathable tape, coupled to at least four electrodes. The device comprises impedance circuitry coupled to the at least four electrodes and configured to measure respiration of the patient to detect sleep apnea and/or hypopnea. The impedance circuitry may be used to measure hydration of the patient. An accelerometer can be mechanically coupled to the adherent patch such that the accelerometer can be coupled to and move with the skin of the patient. Electrocardiogram circuitry to generate an electrocardiogram signal may be coupled to at least two of the at least four electrodes to detect the sleep apnea and/or hypopnea.
