Respiration detection

The respiration rate is the sum of the respirations that have exceeded the detection limit.
The dotted lines present the zero line and the detection limit. The signal strength produced by a
respiration should thus exceed this minimum limit to be included in the respiration rate
calculation. Peaks within the grids are not calculated.
%
If the detection mode is AUTO, the grid lines present the minimum limits. The limits in use may
be larger. The RR value could include fewer respirations than indicated by the gridline.

Respiration rate calculation

Respiration rate is calculated automatically when ECG or CO
respiration measurement is turned off. When CO
