Communication; Memory Features - Nonin Avant 4100 Operator's Manual

C o m m u n i c a t i o n
This chapter describes the memory, printing, and real-time capabilities of the Avant
4000 Digital Pulse Oximetry System.

Memory Features

The display unit can collect and store up to 33.5 hours of SpO
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
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. (See "Displays,
Indicators, and Controls" for more information about setting the clock.) Only
recording sessions greater than one minute in length are stored in memory.
Patient SpO and pulse rate are sampled every 2 seconds. The extreme value is
2
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 two pulses per minute in the interval from 201 to 300.
WARNING: The battery pack must be installed at all times while the
device is operating—even when operating on AC power. If it
is necessary to operate the device without batteries, audible
alarms and memory functions may not be available. DO NOT
use the device without batteries when patient safety relies
upon audible alarms.
