In one embodiment, an external second medical device is capable of being attached to a patient. The second medical device includes an operation module that is capable of operating at different capacities, such as at a first capacity and a second capacity. The second medical device also includes a receiver for receiving a warning about an impending administration of a first treatment to the patient, by a first medical device that does not know about the second medical device being attached to the patient. In response to receiving the warning, the second medical device undertakes a defensive action, whereby the operation of the operation module is capable of being performed at the second capacity. This way, the first treatment, when administered, will impact the second medical device less or not at all.

Methods to control the delivery of CPR to a patient through a mechanical CPR device are described. The method generally allows for a gradual increase in the frequency of CPR cycles. The gradual increase can be regulated by protocols programmed within the CPR device such as intermittently starting and stopping the delivery of CPR accelerating the delivery of CPR, stepping up the CPR frequency, increasing the force of CPR, and adjusting the ratio of compression and decompression in a CPR cycle. Combinations of each of these forms may also be used to control the delivery of CPR. This manner of gradually accelerating artificial blood flow during the first minutes of mechanical CPR delivery can serve to lessen the potential for ischemia/reperfusion injury in the patient who receives mechanical CPR treatment.

An apparatus and method is provided for a defibrillator that specifies treatment protocols in terms of number of chest compressions instead of time intervals. The defibrillator includes a connection port that is configured to attach with a plurality of electrodes that are capable of delivery of a defibrillation shock and/or sensing one or more physical parameters. An energy storage device capable of storing a charge is attached to the plurality of electrodes. A controller is coupled to the plurality of electrodes and the energy storage device, the controller is configured to provide CPR chest compression instructions in terms of the numbers of CPR chest compressions.

Volume adjustment based on listener position is disclosed. A position of one or more speakers is identified, and a position of a listener is tracked. For each of the one or more speakers, a changing distance between that speaker and the listener is assessed. A volume of that speaker is automatically adjusted in real-time based on a current distance between that speaker and the listener.
