Systems and methods are disclosed herein for monitoring the status of an ambulatory medical device and the health condition of a subject that receives therapy from the ambulatory medical device. The ambulatory medical device can have a touchscreen display user interface to receive input signals from a user and display alarm conditions associated with the status of an ambulatory medical device or health condition of a subject. The disclosed methods and systems can determine whether status information received from a monitoring system interface satisfies an alarm condition for the ambulatory medicament device or for the subject. If the status information satisfies an alarm condition, the touchscreen user interface can display one or more alarm status indicators corresponding to the alarm condition. The user can activate a therapy change interface on the touchscreen display and modify a control parameter of the ambulatory medical device that controls the therapy delivery to the subject.
