Alarms

Introduction

Alarm conditions which require immediate or priority user attention can be distinguished from normal status alarms at a distance via their highlighted screen colors, audible annunciation, and alarm status LEDs. If a user is too far away from MOVES® SLC™ to see the contents of the display, the user will still be informed of the alarm condition by seeing that the status LEDs are not green.

The four status LEDs are situated on the top corners of the MOVES® SLC™. They are placed away from the display so that they can be seen when the display cannot. For additional details regarding standard alarms, please refer to the Operator Manual (pages 237-238).

  • When the system is NOT in alarm, the status LEDs are solid green.
  • When the system is IN alarm, the status LEDS are solid yellow, flashing yellow, or flashing red (from low to medium to high in order of priority).
  • If alarms have been silenced, the status LEDs continue to indicate alarm level.

Alarm Limits Screen

The Alarm Limits Screen allows for control of alarm limit values. When the Jog Wheel is rotated clockwise, the selection order for the buttons on the Alarm Limits screen is the following: Screen Button, Alarm View Button, Limit List (limits are selected from top to bottom). When the Jog Wheel is rotated counterclockwise, the order is reversed.

A list of limits is displayed and the threshold name and value, along with the units of each limit, is shown. The list is scrollable once the Limit List part of the screen is activated.
If no limits have been changed from their default values, the phrase “All limits at default” is shown at right below the Status Bar (shown in red in the figure above).

If any limits have been changed from their default values, an icon and a summary of the number of limits not at their default value is displayed (shown in red in the figure above).

Note: The full list of Alarm Limits and Defaults can be found in Table. 30 on pages 188-189 of the Operator Manual.

Alarm Limits Active

If the Limit List is active, a single limit is selected, as indicated by a yellow box around the limit, as shown in the figure below. To modify the limit, the user presses the Jog Wheel to make the limit active and then uses the Wheel to select a value. The Jog Wheel is pressed once again to confirm the new value. The Back Button is used to abandon an actively selected limit and its new value and return to the previously selected limit value.

Limit values that have been changed from their default are shown with an asterisk. Also, an icon in the status bar indicates that limit values have been changed and accompanying text lists how many. As well, a message at the right below the status bar shows the number of limits not at their default values.

Alarm On/Off Screen

The Alarm On / Off screen allows for alarm On / Off control. When the Jog Wheel is rotated clockwise, the selection order for Alarm ON/OFF screen buttons is Screen Button, Alarm View Button, Alarm list (the Alarm list is selected from top to bottom with no wrap). When the Jog Wheel is rotated counter clockwise, the selection order is reversed.

A summary of the alarms turned off is shown at top right (boxed in red in the figure above) as follows: All Alarms ON, 1 Alarm OFF, 2 Alarms OFF, etc. The screen presents a list of all alarms that can be turned off. The list is sorted when the user enters the screen according to the following:

  1. First according to last active, with alarms that are active now at the top.
  2. Alphabetically according to the alarm message.

Alarm level is indicated to the right as shown in the figure above. A red “H” indicates a HIGH priority alarm; a yellow “M” indicates a MEDIUM priority alarm; a yellow “L” indicates a LOW priority alarm. The letters “msg” denote a “MESSAGE”, not an alarm.

The last active column indicates the current state of the alarm. The text “NOW” indicates the alarm is currently active (even if it is turned off). The text “never” indicates the alarm has never been active since the device was turned on. Otherwise the time since the alarm was last active is given (first in seconds, then minutes and finally hours). In this case the priority level listed is the last active priority.

Note: Alarms and messages shown with a padlock beside them in the alarm list cannot be turned off or altered in any way, even by someone with Administrator privileges.

Alarm On/Off List Active

If the Alarm list is activated, one alarm in the list is selected. This is indicated by a yellow selection box. Turning the Jog Wheel clockwise or counter clockwise selects the next or previous item in the list, scrolling the list as needed.

Pressing the Jog Wheel toggles the ON/OFF state of the selected alarm and updates the alarm summary. Pressing the Back Button exits the list active state.

Inverted Display of Patient Monitoring Values (Main Screen)

Normally, patient monitoring values on the Main Screen are shown in their representative colors (e.g., Temp 1 in tan, Temp 2 in turquoise) against a black background (see example below). However, when an active alarm is associated with monitoring value, the values are shown in either white or black against a background of their representative color.

The right image shows the Inverted Display of
Temperature (Alarm Condition)

Note: The active state of the alarm will be indicated by inverted display regardless of whether the alarm is on or off. For example, if the patient temperature is high, causing an alarm condition, the patient temperature is drawn in reverse color, even if the patient temperature alarm has been turned off by the user. If an alarm is latched, meaning it must be acknowledged by the user even if the alarm condition no longer active, the monitoring display is only inverted while the alarm condition is active.

Alarms Icons

Alarms that are not Locked can be turned OFF using the Alarm ON/OFF screen. The red icon containing a white triangle with an “X” through it indicates that some alarms have been turned off. This icon is shown in the top left corner of the Status Bar. The number of alarms turned off is indicated below the icon.

The green icon shown above indicates that some (or all) alarm limits have changed from their default values. Number below indicates how many alarm limits have been changed.

The yellow icon containing a bell with an “X” through it means the alarms audio is OFF or PAUSED. If it is a dashed line “X” like shown above, the alarm audio is PAUSED and the numbers display how many minutes and/or seconds remain for audio pause. If it is a solid line “X”, the alarm audio is OFF.
