Well, a friend of mine (who got me onto yahoo answers, actually) told me about how when she had surgery, they punctured her lung, so she had to keep measuring lung capacity to make sure she was healing. Men have slightly higher residual lung volumes because they tend to have larger bodies and lungs. Exercise capacity tests can be used to measure what people are able to do. If you have a lung disease, such as asthma, your doctor may test your peak inspiratory flow (PIF) and peak expiratory flow (PEF) to measure the amount of air you can inhale and exhale. Tidal volumes increase during deep sleep and with relaxation, but decrease with stress, nervousness and panic attacks. After you have done this, simply follow these eight simple steps to effectively perform the test.1 1.
