[Parameters of mechanical ventilation].
Approximately 50% of children admitted to a pediatric intensive care unit require mechanical ventilation. The most important parameters to program in mechanical ventilation are the ventilation mode, (volume, pressure or dual), modality (controlled, assisted, support ventilation), and respiratory parameters. The main parameters are tidal volume and minute volume in volume modalities, peak pressure (in pressure modalities), respiratory frequency, positive end expiratory pressure, inspiratory time, inspiratory flow, inspiratory-to-expiratory ratio, time of pause, trigger sensitivity, support pressure, and expiratory trigger sensitivity. Moreover, to detect problems in the ventilator and changes in the patient, alarms for tidal and minute volume, peak pressure, respiratory frequency, FiO2, and apnea must be programmed.
