NCT01204281

Brief Summary

To evaluate the effectiveness of high assistance proportional assist ventilation (PAV+) (objective 80% gain) as main ventilatory support in early stage of critically ill patients in comparison with standard volume-assist control ventilation (ACV).

Outcome Measures

Primary Outcomes (1)

  • Length of mechanical ventilation

    Reduction of mechanical ventilation days when ventilated with high assistance PAV+ compared with ACV.

    28 days

Secondary Outcomes (3)

  • Non-inferiority of PAV+ compared to ACV in terms of gas exchange

    28 days

  • Noninferiority of PAV in short term complications

    28 days

  • Noninferiority of PAV in weaning success

    28 days

Study Arms (2)

High assistance PAV+

EXPERIMENTAL

Ventilatory support performed by PAV at 80% assistance (PB 840-plus) FiO2 and PEEP according to routine practice

Other: Mechanical ventilation mode (PAV+ vs. ACV)

Assist-control ventilation

ACTIVE COMPARATOR

Tidal volume, FiO2 and PEEP set according to routine practice

Other: Mechanical ventilation mode (PAV+ vs. ACV)

Interventions

Compare two ventilatory modes in the acute phase of illness
