1. Spirometer is one of the equipment's used for basic Pulmonary Function Tests (PFTs). It is useful as a preliminary test of the health condition for patient's lung. Lung diseases such as asthma, bronchitis, and emphysema can be ruled out from the tests. In addition, it is often used for finding the cause for shortness of breath, assessing the effects of contaminants on lung functions, effect of medication, and progress for disease treatment.asthmabronchitis emphysema

6. How much air can my lungs hold? If the "inspiratory reserve" and the "expiratory reserve" and the "tidal volume" are added together, then you get the "vital capacity," or the functional capacity of the lungs. The vital capacity is the greatest change in volume that can occur in the lungs. This is not the total volume of air that fits in the lungs, but it is a good approximation
