Communication
This chapter describes the memory, printing, and real-time capabilities of the XXX
Pulse Oximetry System.
Memory Features
The display unit can collect and store up to 33.5 hours of SpO
2
and pulse rate
information.
Data may be played back with data retrieval software (NONIN’s nVISION
®
software is recommended). If you wish to create your own software, contact
NONIN for the data format.
NOTE: Only SpO
2
and pulse rate data are available for data retrieval.
The memory in the system functions much like an “endless loop” tape. When the
memory fills up, the unit begins overwriting the oldest data with the new data.
Each time the system is turned on, the current time/date information (if the clock
is set properly) is stored in memory, starting a new recording session. Only recording
sessions greater than one minute in length are stored in memory.
Patient SpO
2
and pulse rate are sampled every 2 seconds. The extreme value is
stored every 4 seconds. Oxygen saturation values are stored in 1% increments in the
range of 0 to 100%.
The stored pulse rate ranges from 18 to 300 pulses per minute. The stored values
are in increments of one pulse per minute in the interval from 18 to 200, and in
increments of 2 pulses per minute in the interval from 201 to 300.
