Claims8
A method, comprising:
- measuring, during a detection mode of a sinus treatment device, an electrical impedance between a treatment electrode of the sinus treatment device and a return electrode of the sinus treatment device as the treatment electrode moves across a face of a user and the return electrode is in contact with a hand of the user;
- converting the electrical impedance to a detected impedance variable by performing an analog to digital conversion;
- establishing, during the detection mode, a trigger condition based on the detected impedance variable;
- triggering a treatment mode of the sinus treatment device when the trigger condition is met;
- and
- passing, during the treatment mode, a therapeutic microcurrent between the treatment electrode and the return electrode through the face of the user by applying a treatment stimulation voltage between the treatment electrode and the return electrode.
