Memory and Data
The WristOx
Model 3150 measures, collects, and stores up to 1,080 hours of SpO
and pulse
2,
2
rate data with a 4-second data collection rate. Data collected at a 1 or 2-second rate reduces
memory capacity to 270 or 540 hours, respectively.
When the memory is full, the device overwrites the oldest existing data with the new data. Each
time the device is turned on, data are automatically stored in memory. Data collection of less
than 1 minute is not retained in memory.
Whenever the 3150 is running for more than one minute, the 3150 creates a record of the
measurements taken and stores them within non-volatile memory. For each record, the current
oximeter time and date are stored to allow quick differentiation of recording sessions. Within
these records, patient SpO
and pulse rate are stored every 4 seconds. The frequency of data
2
storage can be modified from the 4 second default to either 1 or 2 seconds by using nVISION
software. The oxygen saturation values are stored in 1% increments in the range of 0 to 100%.
NOTE: Downloading data in memory does not clear memory. To clear memory, see
"nVISION Settings."
