A medical device displaying data regarding measurement of a physiological parameter, said medical device comprising: a display device; and at least one processor programmed to: display a window for the physiological parameter using the display device, the window including a third indicator identifying a value of the physiological parameter measured in a previous measurement; in response to an automatic trigger of measurement of the physiological parameter, update the window of the previous measurement to further include a first indicator, having a first format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to remove the first indicator and to replace the third indicator with a fifth indicator identifying an updated measured value of the physiological parameter; and in response to a manual trigger of measurement of the physiological parameter, update the window of the previous measurement to replace the third indicator identifying the measured value with a second indicator, in the area vacated by the third indicator, having a second format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to replace the second indicator with a sixth indicator identifying an updated measured value of the physiological parameter; wherein the format of the second indicator is different from the format of the first indicator. a display device; and at least one processor programmed to: display a window for the physiological parameter using the display device, the window including a third indicator identifying a value of the physiological parameter measured in a previous measurement; in response to an automatic trigger of measurement of the physiological parameter, update the window of the previous measurement to further include a first indicator, having a first format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to remove the first indicator and to replace the third indicator with a fifth indicator identifying an updated measured value of the physiological parameter; and in response to a manual trigger of measurement of the physiological parameter, update the window of the previous measurement to replace the third indicator identifying the measured value with a second indicator, in the area vacated by the third indicator, having a second format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to replace the second indicator with a sixth indicator identifying an updated measured value of the physiological parameter; display a window for the physiological parameter using the display device, the window including a third indicator identifying a value of the physiological parameter measured in a previous measurement; in response to an automatic trigger of measurement of the physiological parameter, update the window of the previous measurement to further include a first indicator, having a first format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to remove the first indicator and to replace the third indicator with a fifth indicator identifying an updated measured value of the physiological parameter; and in response to a manual trigger of measurement of the physiological parameter, update the window of the previous measurement to replace the third indicator identifying the measured value with a second indicator, in the area vacated by the third indicator, having a second format, indicating measurement of the physiological parameter is ongoing, and when the measurement of the physiological parameter is completed, update the window to replace the second indicator with a sixth indicator identifying an updated measured value of the physiological parameter; wherein the format of the second indicator is different from the format of the first indicator.
