Ventilator Hyperinflation and Manual Rib Cage Compression

Compression was performed in 6 sets of 6 cycles, with 1 cycle interval. Ventilatory mode and parameters were maintained.

Mechanical ventilator hyperinflation was performed by increasing the inspiratory pressure to every 5 cmH2O until the total pressure reached 40 cmH2O, remaining the same. In Expiratory Rib Cage Compression associated with ventilator hyperinflation, thoracic compression maneuver was performed at the end of inspiration, at the exact moment of cycling.
