Measurement limitations

Movement artifacts
Changing position, moving the head, moving the arms or shivering may result in movement
artifacts. Also the heart may cause noticeable movement and sometimes this may interfere
with the respiration measurement.
Electrical interference
Electrical devices, such as electrosurgery units and infrared heaters, that emit electromagnetic
disturbance may cause artifacts or disable the respiration measurement completely.
Intermittent mechanical ventilation
During spontaneous breathing the ventilator may at times support the patient's ventilation
with an extra inspiration. If these ventilator inspirations are substantially larger than the
spontaneous breaths, the respiration calculation may mistakenly count only the inspirations
and expirations produced by the ventilator. You can correct this by adjusting the detection
limits manually:
1. Press the
