Restrictive lung diseases, such as pulmonary fibrosis, asbestosis and myasthenia gravis are characterized by reduced residual lung volumes. A Peak flow meter is a hand held device that helps doctors determine asthma and breathing problems accurately. Like the helium dilution technique, nitrogen washout can also underestimate residual lung volume in patients with severely restricted airflow. To combat these symptoms, Rogers and Naranjo suggest patients be sent home with an incentive spirometer device, which measures how deeply an individual can breathe in, and helps encourage taking slow, deep breaths to increase lung capacity. How do you measure your lung capacity? Measuring Lung Capacity 3 3. Having a big air capacity in your lungs means you can distribute oxygen around your body at a faster rate.
