MATERIAL AND METHOD: The study to aim to do the comparison the sensibility between spirometry and pletismography in 20 asthmatic adult free of acute symptoms in basals conditions and to use subsequent of salbutamol spray. RESULTS: Were found to equal value for vital capacity (CV) with p = 0.02 for the both methods. For the total capacity pulmonary (CPT) with p = 0.05, p = 0.02 and increment in residual volume (VA) with p = 0.001 in the pletismography in both conditions (basal and post-salbutamol). The specific conductance (CE) to show p = < 0.001. The flows velocities (VF50, VF25-75) and (VF75, VF75-85) to show similar obstructions for aerial track smaller and smallest with p = < 0.20. CONCLUSION: Than both methods to have the same specificity, but no sensibility. The pletismography apparently to be more sensitive to diagnostic obstruction in airway tract of caliber medium.
