1. A patient electrode adapted to be used with an output device that is configured to emit an alert, comprising:
- a pad configured to be attached onto a skin of a patient;
an electrode lead coupled to the pad;
a plug coupled to the electrode lead, and adapted to be plugged into a socket; and
a contact detector coupled to the pad, the contact detector adapted to be in one of a plurality of detector states, andin which the output device is adapted to emit an alert responsive to a determination from a current one of the detector states that the pad does not contact fully the skin of the patient.

Abstract
Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient'"'"'s skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.

22. A patient electrode adapted to be used with an output device that is configured to emit an alert, comprising:
-
a pad adapted to be attached onto a skin of a patient; an electrode lead coupled to the pad; and a contact detector coupled to the pad, the contact detector being a capacitive sensor, the contact detector adapted to be in one of a plurality of detector states that indicate a detected capacitance from a mass of the patient, and in which the output device is adapted to emit an alert responsive to a determination from a current one of the detector states that the pad does not contact fully the skin of the patient, the determination being made when the detected capacitance changes beyond a threshold. - View Dependent Claims (23, 24, 25, 26)

27. A patient electrode adapted to be used with an output device that is configured to emit an alert, comprising:
-
a pad adapted to be attached onto a skin of a patient; an electrode lead coupled to the pad; and a contact detector coupled to the pad, the contact detector adapted to be in one of a plurality of detector states, and in which a wireless sense signal is generated that encodes the current one of the detector states, and the output device is adapted to receive a version of the sense signal, and to emit an alert responsive to a determination from a current one of the detector states that the pad does not contact fully the skin of the patient. - View Dependent Claims (28, 29, 30)
