Adjustable Alarm Limit Ranges
With the exception of bellows respiration, each parameter alarm has adjustable limits as indicated in
the tables below. Note that the alarm limit numeric values can be set to off, with the exception of
O2, N2O, FiCO2. The MR400 also prevents crossover of low and high alarm limit settings, and a
minimum number of units separates these low and high settings. When a parameter has been
turned off, its alarm limits will be off. Alarm limits are adjustable by the same resolution specified in
each parameter's measurement resolution set forth in Appendix A.
The minimum and maximum values for the low and high limits represent the most extreme settings
possible. For some vital signs, these values can be obtained for a low or high alarm limit only if
the other limit is off.
The table below provides the alarm limit ranges for the MR400
