Summary

The researchers hypothesized that the aid of the resuscitator by the technique Air Stacking increase lung volume, promoting increased lung compliance and improvement of the ventilatory pattern. In addition, Air Stacking does not depend on patient collaboration. The objective of this study was to compare the effects of breath stacking and air stacking techniques on respiratory mechanics and ventilatory pattern in patients admitted to the ICU

Conditions

  • Mechanical Ventilation
  • Lung Infection

Interventions

PROCEDURE

Breath Stacking

Patients were connected to a unidirectional valve coupled to artificial airway (tracheostomy), with bacteriological filter. The ventilator was coupled to the unidirectional valve to measure inspiratory volume mobilized in each cycle and a connection to adapt a manometer. The patient performed successive inspirations for a maximum period of 30 seconds or until unidirectional valve opening or volume increase was observed for 2 consecutive efforts. Ten cycles of the technique were performed, with an interval of 30 seconds.

PROCEDURE

Air Stacking

The same system of monitoring and adaptation of the ventilometer and manometer was carried out. A manual resuscitator coupled to a unidirectional valve was used, both connected to the tracheostomy, with a filter interface. Slow and successive inspirations were performed through slow compression of the resuscitator until the maximum inspiratory pressure reached 40 cmH2O. Ten cycles of the technique were performed, with an interval of 30 seconds.
