In addition, the current TLV levels for silica-containing dusts do not take into account any pulmonary ventilation normalization, therefore they are inadequate to protect exposed workers.
To conclude, there is strong relationship between VO2 and its other parameters (VCO/VO values, the duration of the test, the maximal pulmonary ventilation (VE), the maximal heart rate (HR), and the respiratory exchange ratio) of male soccer players who competed in regional soccer league.

A total of 18/21 (85.7%) patients required mechanical pulmonary ventilation during the PICU stay.

Changes in room size and ventilation rate affect risk more than changes in pulmonary ventilation in these scenarios.
To obtain quality images of the lungs, radiologic technologists must be familiar with thoracic anatomy, pulmonary ventilation, the types of ILD and the common radiologic findings associated with ILD.

In our study, the heterogeneity in the ventilation distribution correlated significantly with not only a decrease in pulmonary volumes but also a reduction in the strength of respiratory muscles, which suggests that extrapulmonary mechanisms are also implicated in the worsening of pulmonary ventilation in adults with SCA.
Nevertheless, her pulmonary ventilation and perfusion scanning [Figure 1]a and [Figure 1]b showed a defect in lower lobe of the left lung, which did not match the pulmonary ventilation imaging, led to the diagnosis of "pulmonary embolism." Her renal biopsy showed: 3/17 glomerular sclerosis, 7/17 coagulation necrosis, a portion of tubular epithelial necrosis, bare basement membrane formation, a large number of cellular pipe, particle of tube formation; a large number of lymph plasma cells and eosinophil granulocyte infiltration in interstitium, arteriolar wall thickening, and hyaline degeneration.
