The purpose of this study is to find out if NAVA-technology is better in detecting patients
own inspiratory efforts during mechanical ventilation than currently used flow-triggering in
PRVC (pressure regulated volume controlled) ventilation, and if NAVA gives real benefits for
patients or not.
The investigators study hypothesis is that NAVA-technology can detect spontaneous inspiration
more accurately than currently used methods, and thus will lead to more smooth adaptation to
mechanical ventilation in pediatric patients. The investigators expect this to decrease the
time of ventilatory support needed.
