Methods and devices useful for monitoring a patient and for monitoring and displaying the value of a physiological parameter are disclosed. In one embodiment, a user interface for a medical monitoring device is provided. The user interface can have a monitoring screen with a current value screen and a trend screen. The current value screen can displaying a graphical representation of a value of a physiological parameter over time, e.g., over a current time period, and the trend screen can display a graphical representation of a mean value of the physiological parameter over time, e.g., over a historical time period. The time periods c an be adjustable. In some embodiments, an out-of-limit condition for the physiological parameter can be indicated with shading. For example, the current value screen can display shading between a trendline representing the value of the physiological parameter and a threshold line, which sets the alarm threshold. The historical value screen can display shading between a trendli ne representing the value of the physiological parameter and another threshold line. In yet othe r embodiments, the user interface can provide an event marking screen. The event marking screen can provide the ability to mark events, e.g., delivery of a drug to the patient, adjustment of a sensor, and so on, on a historical trend screen that displays a value of the physiological parameter over time. Such event marking can enable a caregiver to correlate events to a change in a patient's condition as manifested by the physiological parameter.
