The MX40 has two different types of alarms: physiological alarms and
INOPs. For MX40 devices operating with IntelliVue Information Center
Release L and M, physiological alarms are not available locally on the
MX40. INOPs are displayed as described here.
For MX40 devices operating with IntelliVue Information Center Release N
or IntelliVue Information Center iX, physiological alarms are available
locally on the MX40 regardless of network connection to the Information
Center. Alarm settings are as configured by the Information Center.
Changes to physiological alarm settings can only be made at the
Information Center. Audible alarm indicators are annunciated only when
operating in Monitor Mode or when the MX40 is not networked connected.
Physiological alarms are red and yellow alarms. A red alarm indicates a
high priority patient alarm such as a potentially life threatening situation
(for example, asystole). A yellow alarm indicates a lower priority patient
alarm (for example, a low SpO
are short yellow alarms, most of which are specific to arrhythmia-related
patient conditions (for example, ventricular bigeminy).
INOPs are technical alarms, they indicate that the monitor cannot measure
or detect alarm conditions reliably. If an INOP interrupts monitoring and
alarm detection (for example, LEADS OFF), the monitor places a question
mark in place of the measurement numeric and an audible indicator tone
will be sounded. INOPs without this audible indicator indicate that there
may be a problem with the reliability of the data, but that monitoring is not
Most INOPs are light blue, however there are a small number of INOPs
which are always yellow or red to indicate a severity corresponding to red
and yellow alarms. The following INOPs can also be configured as red or
yellow INOPs to provide a severity indication:
ECG LEADS OFF
REPLACE BATTERY (when using disposable batteries)
TELE BATT EMPTY (when using the rechargeable battery pack)
All monitors in a unit should have the same severity configured for these
alarm limit violation). Additionally there
