Introduction
Capnostream stores patient data that provides detailed information on the history of the patient during
monitoring.
The trend displays allow you to look at the patient history as part of the medical analysis to aid in patient
assessment.
The institution can define the trend storage to be: 12 hours of data at 5 seconds resolution, 24 hours of data at
10 seconds resolution, or 72 hours of data at a resolution of 30 seconds. Once trend contents reach maximum
capacity, new data will overwrite the data recorded at the beginning of the stored trend data.
The trend data stores the following parameters:
•
Time, Date, EtCO
2
, RR, SpO
2
, PR, IPI (where relevant)
•
High priority red urgent alarms and yellow caution alarms
•
Equipment-caused events such as CLEARING FILTERLINE or other monitor-related messages.
•
Event markers input by the user, along with any event label.
•
CASE START marker to indicate start of case
•
Count of alarm occurrences (for all High Priority red urgent and yellow caution alarms)
Please note that A/hr and ODI (even if available) do not appear on the Trend screens or printouts. A/hr and ODI
are recorded, and can be viewed, on the Apnea and O
2
Desaturation Report screen and printout. For more
details, see Apnea and O2 Desaturation Report on page 93 .
Changing the resolution of how often data is stored can be done in the Institutional Defaults screen only (See
Institutional Defaults on page 119 ).
Note: Changing the resolution setting will clear the trend data previously stored in memory.
The trend data can be viewed on the monitor, printed, and downloaded via an RS-232 connection or a USB
flash memory device for transfer to a computer for further analysis.
If the patient will be monitored for a longer period than can be stored in the monitor memory, it is
recommended to regularly download patient data using the USB interface as described in
Chapter 12
