1. Explain which measurements can be taken to assess the lung capacity of an individual. Which conclusions can be drawn from knowing the inspiratory reserve volume and the expiratory reservevolume?

6) Spirometry is a technique for quantifying the factors involved in the respiratory process. It is based on volume, time, and airflow measurements. The measurement of how quickly you breathe at a given time interval provides information about a wide range of lung diseases. Tidal volume, inspiration reserve volume, and expiration reserve volume are used to calculate lung capacity. The amount of air forcedly inhaled after the quiet inspiration is referred to as the inspiration reserve volume. 3000 mL is the typical inspiration rate. The lower the IRV, the more likely asthma and diaphragmatic impairment are to occur. The amount of air forcedly exhaled is referred to as the expiration reserve volume. A higher ERV indicates that the lungs are stiff and unable to properly expand or contract.
