A method for routing emergency services calls from a subscribers fixed wireless terminal to a PSAP that serves the location of the subscriber and for delivering traditional landline ALI information associated with the subscriber to the PSAP. The method includes: (a) querying a subscriber database using the subscribers calling party identifier, wherein the calling party identifier is one or more of an MSISDN, MDN, Calling Party Address or ANI; (b) determining that the subscriber is associated with a fixed wireless terminal; (c) assigning the subscribers MSISDN as the calling party identifier; (d) assigning Selective Router routing information, wherein the routing information comprises trunk select digits or an ESRN; (e) routing the emergency services call using the assigned Selective Router routing information to the Selective Router and including the MSISDN as the calling party number; and (f) delivering the emergency services call to the PSAP including an ESN assigned to the MSISDN. The method provides routing by TrunkSelect+MSISDN and routing by ESRN+MSISDN, in place of the wireless industry-standard TrunkSelect+ESRK.

A Wearable Cardiac Defibrillator system includes a support structure with one or more electrodes in an unbiased state. Different sensor modules may monitor, for the long-term, different patient parameters such as the patients motion, a physiological parameter, etc., other than the patients ECG. The sensor modules can be worn by the patient concurrently, or only one at a time as convenient, and may provide respective sensor signals. The system may determine from one or more of the available received signals whether a certain threshold has been reached, such as when the patient is having an actionable episode. If so, at least one electrode may become mechanically biased against the patients body, for making good electrical contact. Then, an ECG reading may be taken and/or electrical therapy may be administered. Since good electrical contact with the skin is not required, the patients discomfort may be reduced and compliance may be increased.

In embodiments, a wearable cardiac defibrillation (WCD) system includes one or more flexible ECG electrodes. The WCD system may have a support structure that is dimensioned to be worn so as to press the electrodes towards the body of the patient. The electrodes may be made from appropriate material so as to flex in order to match a contour of the body of the patient. An advantage over the prior art is that the flexible electrode may make better electrical contact with the patients skin, and therefore provide a better ECG signal for the WCD system to perform its diagnosis.

A transthoracic defibrillator for external defibrillation comprises at least three electrodes configured to be attached to the thorax of a patient to establish at least two electrical paths across the thoracic cavity and through the heart of the patient. In addition, a defibrillator circuit contained in a defibrillator housing has the capability to deliver a different defibrillation waveform across each of the at least two electrical paths.

Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patients 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.
