4-26 Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual

Operation

Trend Display

Once the Trend Display touch key icon is selected, the trend data is displayed on the main screen.

The Radical-7 Pulse CO-Oximeter stores one data set of SpO

, pulse rate, SpMet, SpCO,

SpHb, SpOC, PI, PVI 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-7 Pulse

CO-Oximeter can store between 72 hours and > 10 days of trend data. The Radical-7 Pulse

CO-Oximeter 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-7 Pulse CO-Oximeter only stores data in the trend memory while the instrument is

turned on, and the trend data remains in memory until the memory is full, 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

UP TO 72 HOURS (APPROXIMATELY 3 DAYS)

10 SECONDS

> 10 DAYS

The Trend Display can be configured to display one or two of any of the available trend

parameters/measurements (SpO

, SpMet, SpCO, SpHb, SpOC, pulse rate, PI or PVI) selected

by the user. The instrument is storing all parameters/measurements in trend memory, but can

only display one or two user selected parameters/measurements at any one time. The Trend

Display can be adjusted to the desired parameter/measurement by selecting Trend from the

Main, Display Menu.

TREND AUTO SCALE

The Radical-7 can be set to automatically change the trend data field by adjusting the area

(scale) of the graph that is shown. The scale of the trended graph is adjusted to focus on the

values of the data presented. The movable area of focus allows improved data viewing. As

the data trends up or down, the Radical-7 automatically adjusts the scale (or viewing area) to

maintain the data within the field of view.
