Mobile Pulmonary Function is a kind of examination for the lungs and thoracic area. Examined breathing sounds for specifically any signs of chronic obstructive pulmonary disease, congestive heart failure and history of lung disease like bronchitis or asthma. Pulmonary function testing results are calibrated in prediction equations. Some diseases associated with abnormal signs may be findings including: asthma, chronic bronchitis and emphysema. Restrictive diseases like pleural thickening, pulmonary fibrosis and congestive heart failure are associated with other abnormalities found in pulmonary function testing. If respirators worn by any employees, examinations and pulmonary function tests then must be performed once a year.
