Study of some ventilation parameters in patients with lung and heart diseases using a domestic volumospirograph

Despite the lack of clear boundaries of the norm, the flow indices according to spirography allow early diagnosis of bronchial permeability disorders, which facilitates the diagnosis of obstructive bronchitis and bronchial asthma.
