When conditions requiring immediate operator interaction are detected by the LTV
®
Series ventilator,
an alarm is generated. Some alarms can reset themselves, for instance, a high pressure alarm that is
caused by a cough. Other alarms require some action from the operator and the audible and visual
alarms will continue until the problem is corrected.
When an alarm occurs:
• A flashing alarm message appears in the display window.
• An audible alarm sounds.
• Any associated control displays flash.
• Depending on the alarm, other actions may be taken, such as terminating an inspiration or
opening the exhalation valve.
When an alarm condition clears:
• The audible alarm is silenced.
• The alarm message continues to flash in the display window.
• Any associated control displays continue to flash.
WARNING
Adjustable and Critical Alarms – For safety purposes, all adjustable alarms and all critical alarms
must be checked to insure proper operation.
Audible Alarms - Failure to immediately identify and correct audible alarm situations may result in
serious patient injury.
