Data
To review data, there must already be a file started by patient sampling. Tap the Review StO
2
button to the right of the desired
channel’s StO
2
graph. The Review StO
2
screen is displayed. Refer to Figure 11.
A graph is displayed for the amount of time elapsed from the moment sampling was started to the moment the
Review StO
2
button was
pressed. Move through the graph by using the arrows. Pressing the double arrows moves through the graph page by page (a page is the
total number of data points (90) that can be shown on one page of the graphic area). Pressing the single arrows moves through the
graph in smaller sections of data; the vertical cursor can also be positioned by tapping the screen.
The y-axis displays the percentage of StO
2
in the tissue being measured. The y-axis does not auto-adjust. The x-axis displays the data
points as they are gathered and represents the time scale. The red dotted line(s) across the graph indicates the alarm level(s) and
indicates where the data points fall with regard to the alarm level(s). The set alarm level is presented numerically to the left of the graph.
Use the
Zoom +/- buttons to display the data in different time increments. Press the up or down arrows to select the desired time
increment. For example, pressing 50% means that the data on one page represents averaged data points in 5-minute increments; refer to
Table 4.
