Adjusting the Alarm Limits
Alarm limits can be set to a wide range of values, including off (with the exception of O2,
N2O and FiCO2). It is the responsibility of the operator of the MR400 to ensure that alarm
limit values appropriate for each patient are established and set. Failure to do so may cause
a lapse in patient monitoring.
The MR400 provides versatile methods to control the settings for the patient parameter alarms.
Each patient parameter (with the exception of bellows respiration) has a low and high alarm limit
setting (see the table on page 4‐22), which can be changed manually or automatically, unless the
parameter is off.
Alarm Limit Controls
Individual alarm limit settings can be adjusted by touching the respective parameter label in the
Alarms or the Gas Alarms menu.
