6 Alarms
6.1 Overview
The monitor gives audible or visual alarms to indicate the medical staff, when a vital sign of the
patient appears abnormal, or mechanical or electrical problems occur to the monitor.
Upon turning on the monitor, the alarm indicator will flash once in yellow and red. Then, a beep
will be heard. This is used to verify the audible and visual alarm function of the monitor. If no
beep is heard, or the alarm indicator doesn’t flash normally, please do not use the monitor, and
contact our customer service.
For details about alarm setup of this monitor, please refer to 4.4.2 Alarm Setup.
6.1.1 Alarm Categories
The alarms are divided into three categories: physiological alarms, technical alarms and prompt
information.
1. Physiological alarms
A physiological alarm either indicates that a monitored physiological parameter is out of
specified limits or indicates an abnormal patient condition. For example: HR TOO LOW,
ECG LOST or RESP ARTIFACT, etc. Physiological alarm messages are displayed in the
physiological alarms area of the main screen.
2. Technical alarms
Technical alarms are also referred to as system error messages. A technical alarm indicates
that the monitor or parts of the monitor is not capable of accurately monitoring the patient’s
condition due to improper operation or system failure. For example: ECG INIT ERR or
TEMP SELFTEST ERROR, etc. Technical alarm messages are usually displayed in the
technical alarms area of the main screen. But the technical alarms related to NIBP are
displayed in the lower part of the NIBP parameter window.
3. Prompt information
Strictly speaking, prompt information cannot be counted in alarms. It is usually information
relating to the system, but not concerning vital signs of patients. For example, the monitor
prompts “NIBP alarm disabled!” at the time the monitor is powered on. Besides, if a
parameter module is turned on but the required leads or sensor are not connected, the
monitor will prompt accordingly, such as “ECG LEAD OFF” or “SPO2 SENSOR OFF”, etc.
Prompt information is usually displayed in the technical alarms area. But the prompt
information relating to NIBP is displayed in the lower part of the NIBP paramter window.
NOTE
z To distinguish from the prompt information, the alarm message is displayed
with yellow or red background.
