Once the Trend Display touch key icon is selected the trend data is displayed on the main
screen. The Radical stores one data set of SpO
2
, pulse rate and system messages in a
dedicated memory area. Depending on the Trend Period, a setting for how often the data
is stored in the trend memory, the Radical can store between 72 hours and 30 days worth
of trend data. The Radical also employs a sophisticated data compression scheme. The
actual amount of trend data that is stored is dependent on the type of data that is collected.
The Radical only stores data in the trend memory while the device is turned on, and the
trend data remains in memory until the memory fills up, or is cleared by the user.
CAUTION: CHANGING THE DATE AND TIME OF THE SYSTEM CLOCK, OR
CHANGING THE TREND PERIOD, WILL ALSO CLEAR THE DATA IN THE TREND
MEMORY.
The following table outlines the trend capacity for sample Trend Period settings:
TREND PERIOD TREND MEMORY CAPACITY
2 SECONDS MINIMUM OF 72 HOURS (3 DAYS)
10 SECONDS TYPICALLY 720 HOURS (30 DAYS)
