NCT01193023

Brief Summary

The purpose of this study is to document the prevalence and type of asynchronies incidence during invasive mechanical ventilation in pediatric patients breathing under pressure support. And to observe the impact of adjusting the expiratory trigger setting on asynchronies, and compare these incidences with asynchronies measured in pediatric patient breathing under NAVA system (Neurally Adjusted Ventilatory Assist).

Outcome Measures

Primary Outcomes (1)

  • asynchronies

    Asynchronies during mechanical ventilation are the following: Auto triggering, double triggering, late cycling, premature cycling and ineffective effort. all ventilatory parameters are recorded under Pressure support (3 phases: 3 levels of expiratory trigger setting, initial, +10% and -10%, 15 min, 5 min and 5 min respectively) and NAVA (1 phase, 20 min). Asynchronies will be determined by measuring each ventilatory cycle of all recordings.

    12 months

Study Arms (2)

Pressure support

ACTIVE COMPARATOR

in this arm, pressure support will be recorded under 3 conditions: * with the initial Expiratory Trigger Setting (ETS) * with ETS +10% * with ETS -10%

Other: Pressure Support

NAVA

EXPERIMENTAL

Neurally Adjusted ventilatory Assist is a ventilation mode where the ventilator is piloted by the electrical activity of the diaphragm Ventilation is triggered and cycled off by the electrical activity of the diaphragm, the pressure delivered being proportional to this activity.

Device: NAVA
