[Hyperventilation syndrome in bronchial asthma, essential hypertension and organic neurosis. Clinical picture and external respiration function]. / Giperventiliatsionnyi sindrom pri bronkhial'noi astme, gipertonicheskoi bolezni i organnom nevroze. Klinicheskaia kartina i funktsiia vneshnego dykhaniia.

The external respiration function was studied in 100 patients with hyperventilation syndrome (HVS) divided into 3 groups: 40 patients with HVS and bronchial asthma (group 1) consisting of 15 males and 25 females (age median--45 years, 25 percentile--37 years, 75 percentile--53 years); 39 patients with HVS and essential hypertension (group 2) consisting of 8 males and 31 females (age median 49, 25 percentile--40 years, 75 percentile--57 years); 21 patients with HVS without concurrent somatic diseases of group 3 (7 males, 14 females, age median 45 years, 25 percentile--28 years, 75 percentile--45 years). It is shown that different disorders of pulmonary ventilation correspond to different clinical manifestations of HVS. Thus, in bronchial obstruction (group 1) HVS manifests with "weak respiration", in restrictive pulmonary disorders (group 2) HVS manifests as "heavy respiration", in high parameters of bronchial permeability (group 3)--"shallow respiration".
