Abstract: Systems, devices and methods are provided for monitoring a physiological condition of a patient. An exemplary method involves a computing device obtaining measurement data for the physiological condition of the patient, providing a graphical user interface display pertaining to monitoring the physiological condition of the patient and identifying a toggling condition for the graphical user interface display. In response to the toggling condition, a graphical representation of at least some of the measurement data is automatically provided at the computing device. After providing the graphical representation of at least some of the measurement data, the computing device identifies a second toggling condition while the graphical representation of at least some of the measurement data is presented at the computing device and automatically removes the graphical representation of the at least some of the measurement data from presentation at the computing device in response to the second toggling condition.
