Efeitos da ventilação mecânica não invasiva na mobilidade e assincronia tóraco-abdominal em pacientes com DPOC

Abstract

Introduction: The VMNI has been showing an adjuvant treatment resource for patients with stable COPD or exacerbation. However little is known about the action that the NIV promotes in thoracic and abdominal and mobility if it is able to promote improvement of asynchrony. Objectives: to evaluate the effects of the NIV in thoracic and abdominal mobility, comparing variables in spontaneous breathing and during the use of NIV in patients with COPD by OEP. Methods: Two groups of individuals (GC with 14 healthy and COPD with 16 patients) were assessed in relation to the thoracic-abdominal asynchrony, respiratory and àcontrubuição variables of each thoracic compartment using a Plethysmograph SPOS System (BTS, Italy) in spontaneous breathing and with two VMNI modes. Results: Patients with COPD evaluated presented ATA in home, we also observed that the COPD asynchrony in all compartments in relation to healthy, which in turn has always maintained its AF next to zero and when it observes only the COPD group, using both methods of VMNI promote decrease of asynchrony in compartment CTS vs. ABD and the key changes found in the COPD group are related to the distribution of aid and action of each compartment toracico. Conclusion: There are ATA in patients with COPD, even at home, the degree of airway obstruction of these patients correlates with the presence of asynchronous Thoracoabdominal, the use of VMNI in the mode continuous positive airway pressure is able to improve thoracic abdominal synchrony in patients with COPD, as well as the use of some blood pressure to A6 led and that the VMNI is able to promote changes in compartmental contribution without promoting significant changes in respiratory variables in patients with COPD compared with age-matched healthy.
