Pulmonary ventilation function of patients with mild COPD

IMSP Institutul de Ftiziopneumologie „Chiril Draganiuc”For patients with mild COPD a comprehensive functional-diagnostic study of the system of respiration has been conducted (spirometry, body-plethysmography, pharmacological bronhodilatation test with β2-agonist, pulse oximetry, the identification of the average index for the group of shortness of breath). It has been established that stage I of COPD is characterized by a slight restriction of air flow rate (FEV1/FVC<0,70; FEV1≥80% predicted) and/or restructuring of the residual lung capacity (increased residual lung volume and reduced amount of expiratory reserve) demonstrating the early manifestations of emphysema. Pacienţilor cu evoluţie uşoară BPCO s-au efectuat examinări complexe de diagnostic funcţional ale aparatului respirator (spirometrie, body-pletismografie, testul farmacologic bronhodilatator cu β2-agonist cu durată scurtă de acţiune, puls-oximetrie, determinarea valorii medii pentru grup a indicelui dispneei). S-a stabilit că, stadiul I de BPCO se caracterizează prin limitare uşoară a fluxului de aer (VEMS/СVF
