“…The measurements were performed by trained technicians, following the American Thoracic Society recommendation (Redlich et al, 2014). The lung function measurements included forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV 1 /FVC ratio (FEV1%), peak expiratory flow rate (PEF), forced expiratory flows at 25%, 50%, and 75% of expired volume (FEF 25 ,FEF 50 , and FEF 75 , respectively), and mid expiratory flow rate 25-75% (FEF 25-75% ).…”

Workers from specific occupational settings may be exposed to high fungal bioaerosol concentrations, causing detrimental health effects. Therefore, we conducted a study to evaluate the characteristics and health effects of fungal bioaerosols present on agricultural farms. By using IOM inhalable dust samplers, personal and area samples of airborne fungi were collected from five agricultural farms-two mushroom and three vegetable farms. A standardized questionnaire and spirometry were used to evaluate workers' health. The Kruskal-Wallis test was used to examine the distributions of fungal and environmental factors among the different farms, and regression analyses were performed to evaluate the effects of personal bioaerosol exposure on workers' health. In the personal samples, the geometric mean concentrations ranged from 4.3 × 10 3 to 3.0 × 10 4 CFU m -3 for total culturable fungi and from 4.2 × 10 3 to 1.2 × 10 5 spores m -3 for total fungal spores. The total fungal spore concentrations differed significantly among the personal samples (p = 0.026), but not among the area samples, from the five farms. The culturable fungal concentrations among the five farms did not differ significantly in the personal or area samples. Decreased lung functions of the workers were significantly associated with the concentrations of total fungi and several fungal taxa such as Ascospores, Fusarium, and Periconia. This study demonstrated that exposure to high fungal bioaerosol concentrations reduced the lung functions of the mushroom and vegetable farm workers. Superior ventilation and appropriate personal protection equipment are required to reduce occupational biohazards.

“…The American Thoracic Society spirometry interpretation workshop only states that subjects should be "never-smokers, free of respiratory symptoms and disease." 9 In accordance with these guidelines, exclusion criteria included: the presence of a significant disease other than obesity that could contribute to dyspnea or exercise limitation (ie, metabolic, cardiovascular, neuromuscular, musculoskeletal, history of asthma or COPD, smoking history, obstructive sleep apnea, pulmonary hypertension, obesity hypoventilation or other respiratory diseases, syndromes, or musculoskeletal abnormalities). 10 Subjects not meeting these guidelines were excluded.…”

“…Decrease in MVV may be explained by respiratory muscle inefficiency, increased upper airway resistance, and inspiratory flow resistance. 8,9,43 The decline in MVV in obesity may be due to increased tissue resistance, increased intra-abdominal pressure in obese persons, exaggeration of the normal spinal curvature due to forward displacement of the center of gravity of the body thus causing profound thoracic kyphosis. It leads to elevation of the lower sternum and relative fixation of the chest in a position of moderate inspiration and consequently reduced expiratory reserve volume.…”

BACKGROUND:We investigated the role of mechanical ventilatory constraints in obese class III subjects during incremental exercise. METHODS: We examined 14 control subjects (body mass index [BMI], 23.6 ؎ 3.2 kg/m 2 ), 15 obese class II subjects (BMI, 37.2 ؎ 4.5 kg/m 2 ), and 17 obese class III subjects (BMI, 53.4 ؎ 6.8 kg/m 2 ). All subjects performed pulmonary function tests and maximal inspiratory pressure at rest, ventilatory parameters, flow-volume loops, and rated perceived exertion and breathlessness during exercise. RESULTS: All subjects had normal pulmonary function. Obesity resulted in increased minute ventilation for a given submaximal work rate, although minute ventilation during peak exercise was lowest in the obese class III subjects. Endexpiratory lung volume was significantly lower in the obese subjects at rest and during exercise at the ventilatory threshold but not during peak exercise. During heavy-to-peak exercise, the obese subjects increased their end-expiratory lung volume, whereas the control group continued to decrease this parameter. Compared with controls, end-inspiratory lung volume was significantly lower in obese class II subjects and obese class III subjects at rest and at the ventilatory threshold but not during peak exercise. At maximal exercise, obese class III subjects had a greater endinspiratory lung volume than obese class II subjects and controls. Obese class III subjects displayed a greater expiratory air flow limitation at rest, at the ventilatory threshold, and during peak exercise than both controls and obese class II subjects. CONCLUSIONS: Mechanical ventilatory constraints increase progressively with degrees of obesity, contributing to exercise limitation in obese subjects. Key words: end-expiratory lung volumes; end-inspiratory lung volume; expiratory air flow limitation; breathing strategy; work of breathing; dyspnea. [Respir Care 2015;60(4):549 -560.
