Summary

This is a randomized crossover trial to evaluate the effects of thoracic compression applied alone or in association with hyperinflation maneuver with the ventilator. In addition, the mobilized volume and peak expiratory flow resulting from both maneuvers will be evaluated.

Detailed description

Ventilator hyperinflation is widely used in hypersecretive patients. It consists of increasing alveolar ventilation by facilitating the coughing mechanism so that the secretions of the peripheral airways are mobilized into the central airways so that they can be removed by tracheal aspiration or cough. Thoracic compression consists of manually compressing the rib cage during expiration, in order to increase expiratory flow, mobilize and remove pulmonary secretions. A randomized crossover clinical trial was performed with 30 patients submitted to isolated compression or associated with ventilator hyperinflation, with a 6 hour interval. Patients were evaluated through compliance and resistance of the respiratory system.

Conditions

• Pulmonary Atelectasis

Interventions

Type	Name	Description
OTHER	Expiratory Rib Cage Compression	Compression was performed in 6 sets of 6 cycles, with 1 cycle interval. Ventilatory mode and parameters were maintained.
OTHER	Compression + Ventilator Hyperinflation	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.
