Reanimator of Muller Group (intermittent positive pressure): Patients allocated to this group received intermittent positive pressure breathing (resuscitator Muller, Engemed, Brazil), adjusting the positive pressure around 1.5 kgf / cm2, which corresponds to 15 20 cm / H2O, positive pressure was applied through a face mask (Respironics®), which was connected in a circuit extending along the Muller Resuscitator equipment applied continuously for four series 10 of the patient breaths active and with an interval of two minutes between them in Fowler 45 position

Control Group: In position Fowler 45, patients assigned to this group was administered as treatment lung expansion exercises using the incentive inspiratory flow (Respiron, NCS, Mexico) and concomitantly blocking contralateral to the drain maneuvers were performed, compression / decompression associated with the incentive spirometry (Respiron) consisting of 4 sets of 10 active patient breaths with an interval of two minutes between sets. Since the load of the respiratory stimulator will be zero throughout treatment (Table 1). Guidelines to the active, progressive and early mobilization.

Resuscitator of Muller Group (intermittent positive pressure): Patients allocated to this group received intermittent positive pressure breathing (resuscitator Muller, Engemed, Brazil), adjusting the positive pressure around 1.5 kgf / cm2, which corresponds to 15 20 cm / H2O, positive pressure was applied through a face mask (Respironics®).

Ventilometry was evaluated in two stages: 1) before the intervention, 2) on the day of drain removal or discharge. The spirometer application is according to implement stable and acceptable criteria. TOBIN The measures of lung volumes forão performed with the spirometer (FERRARIS MK8 Wright ®) coupled to a nozzle. The patient was instructed to breathe quietly in the apparatus for a minute to read the minute volume (VM). During this period, it is checked the number of breaths, i.e., respiratory rate (RR) for calculating the tidal volume (VT) given by VC = VM / FR (ml).

Oxygen saturation was assessed in two stages: 1) before the first intervention of the day 2) after daily intervention protocol until hospital discharge or removal of the chest tube. Patients were evaluated with breathing in ambient air (without supplemental oxygen) after 10 minutes of the procedure. The researcher used a pulse oximeter portable.

by visual analogue scale of pain (VAS) was used to determine the degree of soreness daily during the hospitalization period and pre chest drainage and after the intervention.
