Storing Trend Data
Whenever the oximeter is powered on, it stores the SpO
2
and pulse rate readings in
memory every second, regardless of whether the oximeter is in use monitoring a
patient or not. The oximeter can store up to 45 hours of trend data. If desired,
download the 45 hours of stored trend data 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 45 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 45 hours of data, with newly collected data
overwriting the oldest data on a rolling basis. The oximeter continues to record data points
as long as it is powered on, with “blank” data points collected if no OxiMax pulse oximetry
sensor is connected to the oximeter or patient. “Blank” data overwrites older patient data if
the memory is full. To save old patient data, turn the oximeter off when not monitoring a
patient and download the trend memory before it fills up, overwriting the old data with new
data (or “blank” data).
