OXITEST PLUS 7 OPERATING MANUAL
3.10 Selecting Auto Presets
The Auto Preset selections are selectable by pressing the
Auto
key on the front panel until the
desired preset selection appears. Each Auto Preset specifies the SpO
2
level, heart rate, pulse
amplitude and signal artifact settings as a group. The nine default Auto Preset selections are listed in
the table below. These selections may be programmed to alternative values via the RS-232 port,
using the
OxiEdit
software which is available at www.datrend.com.

3.11 Selecting Alarm Tests
The Alarm Test Mode provides the capability of performing autosequenced tests of the alarm
functions on a pulse oximeter. Five different kinds of Alarm Tests are provided: low saturation, high
pulse rate, low pulse rate, low signal level and motion artifact.
The Alarm Test Mode works by switching
Oxitest Plus 7
from a "normal patient" simulation to
an "abnormal patient" simulation, and allowing the user to measure the time the oximeter takes to
produce an audio-visual alarm. After the user records the time of the oximeter alarm, the tester is
reset back to the normal patient simulation, and the user then records time required for the oximeter
to shut off the alarm. The Alarm Test Mode therefore determines
both
the alarm "ON TIME",
and
also the length of time the alarm persists under normal patient conditions, the "OFF TIME".
