Pulmonary Ventilation*

In this clinical trial, 60 patients who suffered from AFB positive infiltrative pulmonary tuberculosis and being cured in consolidative chemotherapy in specialized hospitals, the age from 20 to 59 years old, not sexes distinguish. Kinds of ventilation: 93.33% of patients suffered from restrictive ventilation and the rate of mix ventilation was 6.67%, no participant was obstructive ventilation. Mean values of VC was 53.93%5.97; of Tiffeneau index 80.756.63%

The study was carried out on 2,483 subjects including 1453 male and 1030 female from 8 to 86 years old at various Northern provinces of Vietnam. These subjects were measured by modern lung ventilation function machine and were standardized before measuring. The linear equation of 14 parameters of lung ventilation function was built for each gender at the two groups of ages ≤25 and ≥26 years old. The values of our equation were lower than that of Quanjer’s. However, it wasn’t statistically different from that of other Vietnamese authors.
Pulmonary Ventilation ; Epidemiology

Clinical examination on 87 patients with chronic bronchitis at Vinh Tien - Vinh Bao - Hai Phong in 2003. Results showed that common clinical symptoms are cough and expectorate (100%), breath shortness (88.51%), normal thoracic cavity (63.21%), rales (100%). VC and FVC reduced dramatically (65.52%), FEV1 reduced significantly (71.27%), PEF reduced remarkly (74.72%)

The study carried out pulmonary ventilation functions of 81 professional wrestlers, swimmers, and athletics in Hai Phong by using auto Spiroanalyser - ST 250 from FUKUDA SANGYO of Japan to measure objects in standing position after 15 – 30 minutes of pause. Pulmonary ventilation functions such as VC, FVC and FEV 1% T of wrestles, swimmers and athletics were considerable higher than those of controls. Their PEF, MVV and FV were much higher than those of controls. There was a fast increase of VC, FVC, FEV 1, PEF, MVV and FV after 12 months of training compared with the control group

Study on 75 subjects included 54 silicatosis patients (51 males, 3 females, mean age 43.9±9.8) working in seagoing vessel repairing and new building branch. Control group included 21 people (19 males, 2 females). All of these subjects were working in a labor environment, in which SiO2 dust level exceeded allowable limit from 4 to 21 folds with mean exposed times 16.8±5.2 years. The results showed that: 54 silicatosis patients had remarkable symptoms such as chest pain (83.3%), exercise dyspnea (74.1%), decreased alveolus soughing (59.3%). There were 75.9% in all of patients had pulmonary ventilation disorder, in which mainly were limited pulmonary ventilation disorder (53.7%).
Pulmonary Ventilation ; Patients ; Environment

Study on 33 asthma patients and identifying maximum expiring volume per second and medium flow between expiring stage of living volume from 25% to 75% in asthma patients without severe stuffy treated at Bach Mai hospital in 2000. The results: there was no difference of sex in asthma. 24% of patients with childhood asthma; 0.6% of them with asthma over 20 years and 30% of them with asthma from 10 to 20 years. After treatment, medium expiring gaz flow at the middle of expiring stage at 25% to 75% of living volume decreased down 50.8% compared with theory value. 48% of patient with mixture ventilation disorder. 40% of patients with obstructed ventilation disorder, 24% of patients with pheriperal obstructed ventilation disorder

A study on 234 healthy persons ages from 16-60 (142 male and 92 female) was performed during 1994-1996 and CECA recommendations on ventilatory function had been applied with spiro-analyser ST 300 (Agency Fukuda Japan). The obtained results are as follows: On healthy persons: in men aged from 16-25, regression equations of IVC, FVC, FEV, predicted values increased according to age, coefficient A was positive. On the contrary in women FVC,FEV,MMF, PEF, V75, V50, V25, MVV predicted values also increased according to age, coefficient A therefore was negative. However in both sexes, these predicted values increased with the height but decreased with age.
