Medical devices include patient modules and displays, which are all electrically coupled together. The patient modules include a defibrillation therapy module and optionally a monitoring module. The defibrillation therapy modules have circuitry that can discharge electric, defibrillation shock through defibrillation electrodes. Some of these medical devices treat patients with defibrillation shock therapy and can also monitor various patient parameters. The displays have a tactile user interface that can include a touch screen in some examples. The tactile user interface translates any received tactile input into an instruction for the patient module. Some specific examples of the disclosed medical devices are defibrillators.
