Using Monitor Trend Data
N-600x Operator’s Manual 75
Storing Trend Data
Whenever the N-600x is turned on, it stores the monitor %SpO
2
and
pulse rate readings in memory every 2- or 4-seconds (regardless of
whether the N-600x is monitoring a patient or not). The N-600x can
store up to 48 hours of 4-second trend data or 24 hours of 2-second
trend data. The 48/24 hours of stored trend data can be downloaded to
a printer or a portable computer. Up to 50 alarm limit changes can be
stored in the trend data. If more than 50 alarm limit changes occur
during the 48/24 hours of trend data collection, the additional alarm
limit changes will take space reserved for trend data.
Caution: Changing alarm limit settings uses up trend memory
space. Change alarm limits only as needed.
Note : Trend memory always contains the most recent 48 hours of
data, with newly collected data overwriting the oldest data on a
rolling basis. The N-600x continues to record data points as long as
the monitor is powered on, with “blank” data points collected if no

sensor is connected to the monitor or patient. “Blank” data
overwrites older patient data if the memory becomes full. Therefore,
if you want to save old patient data, it is important that you turn your
monitor off when you are not monitoring a patient, and that you
download the trend memory before it fills up and overwrites the old
data with new data (or “blank” data).
