About

This study evaluates the comparison of two of re-expansion pulmonary physiotherapy in patients with chest tube. The study group received intermittent positive pressure intervention and the control group received incentive spirometry intervention associated with manual operation.

Full description

All the re-expansion methods increase lung volume increasing gradient of transpulmonary pressure (PL) representing the difference alveolar pressure and pleural pressure. Spontaneous deep breath increases the PL by reducing pleural pressure (active breathing exercises, breathing supporters and manual operation).

Muller resuscitator consists of a pneumatic valve feature designed to operate with medical oxygen. It is used intermittently or continuously for pulmonary re-expansion, with lower load imposed work, and increase the efficiency of gas exchange by improving volumes, lung capacity and breathing pattern, and reverse atelectasis.

However, studies show the paucity of data in the literature regarding the Muller Resuscitator in different forms and respiratory rehabilitation protocols. In addition, studies show lack of standardization of methods and resources used in respiratory therapy in patients with chest tube.

32 participants in 2 patient groups

Reanimator Group

Experimental group

Description:

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

Treatment:

Device: Reanimator group

Control Group

Experimental group

Description:

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.
