Study Maximums and Minimums – The study maximums and minimums section contains the
following information:
•
Low SpO
– The lowest recorded SpO
2
•
Time of Lowest SpO
ignore invalid data when determining lowest SpO
•
High PR – The highest recorded pulse rate value taken from the total valid sample.
•
Low PR – The lowest recorded pulse rate value taken from the total valid sample.
•
Avg. SpO
– The average SpO

STD – The standard deviation is a measure of the variability of the sample. The larger
2
the standard deviation of the sample data, the more variability there is in the sample.
5.
Statistics - The statistics section contains information calculated from the valid data only. The
following information is supplied in the statistics section:
•
% Time per SpO
range – This section displays the percent of the valid sample time that
2
the readings were in a specified range. (Sample must be > 1% to be accounted for here.)
•
Time per SpO
range – This section displays the total valid sample time that the readings
2
were in a specified range.
•
Total duration below 90% SpO
SpO
readings were below 90%.
2
•
Total duration 88% SpO
the SpO
readings were 88% and below.

•
Longest single event with SpO
longest single event when the % SpO
•
Started at – This section displays the time the longest single event with SpO
below began.

Summary Complete – This final section will contain a notification that the summary is
complete. This section is important because of the pauses that occur during printing.
NOTE! Only stored data will be printed. Real-time printing is not available.
NOTE! The monitor uses a "relative time" clock. The times indicated on the printout are
relative to the start of the study. When the monitor switches from Verification to
Data Collection Mode, it restarts the "relative" time clock to 00:00:00.

The standard deviation, s, is calculated by:
mean, and n is the number of samples. Note: The data sample is generally not normally distributed.
