(54) SYSTEMS, DEVICES, AND METHODS FOR PROVIDING ELECTROTHERAPY


(57) Systems, devices and methods for providing a pressurized fluid for facilitating conductive gel release prior to providing cardiac therapy to a patient are disclosed. A first system can include a chemical reaction chamber including a first chemical and a second chemical isolated from each other by a mechanical barrier. The mechanical barrier is configured to be compromised upon receiving a signal from an electrotherapy device controller such that the first chemical and second chemical come into contact to produce a sufficient amount of pressurized fluid. An alternative system can include a pressure source comprising a reservoir containing a pressurized fluid. The pressure source can also include at least one release mechanism configured to cause a release of the pressurized fluid from the reservoir to an exit port of the pressure source when a wearable medical device is preparing to deliver a therapeutic shock to a patient.
