Shortness of breath is one of the main complaints that sends people to the doctor's office. One of the tools used to help diagnose the cause of breathlessness is called a spirometer. This is a kind of pulmonary function monitor (PFM) and measures the volume of air inspired and expired through the lungs. The printed output from the device is a graph, and this can indicate whether the breathing dysfunction is restrictive or obstructive. Spirometers are constructed differently to enable different strategies for measuring the movement of air (pressure transducers, ultrasound, water gauge).
Various lung function tests are employed to eliminate serious lung conditions such as bronchitis, asthma and emphysema. They can determine the cause of breathlessness, investigate the effects of medication or airborne contaminants on the lungs and to watch the progress of treatment. They are conducted prior to surgery on the lungs to provide a benchmark of pulmonary function.
It was Claudius Galen, noted Roman physician, who devised the first PFM and conducted the first lung function tests. This took place in the late first or early second century AD. Later instruments were based on a bell jar turned upside down in water. Modern variants include the whole body plethysmograph, peak flow meter and the pneumotachometer.
According to the Mayo Clinic, shortness of breath may be defined as an intense chest tightening and a feeling of being suffocated. It may be confined to a single episode or it may become chronic. While it is important to rule out any serious problems underlying breathlessness, in most cases the root cause is harmless and easily curable.
There half a dozen or so red flag symptoms which, in conjunction with shortness of breath, may point to a serious problem. These red flags include being pale or tired all the time, a chronic cough or wheeze, swollen ankles, difficulty breathing when lying flat, a pain that worsens with exercise, a history of working around asbestos, industrial fumes, wood dust, or in a coal mine and any other persistent or unusual symptoms. If you experience any of the above, then you should consult your doctor.
Asthma is a chronic condition involving inflammation of the airways. It is potentially serious and may be fatal. According to the CDC in Georgia, at any one time in the United States there are 18.9 million non-institutionalized adults diagnosed with this condition. This amounts to 8.2% of the population.
Once all serious problems have been eliminated from consideration, many cases of shortness of breath can be attributed to one of two causes, muscle knots (aka trigger points) or dysfunctional breathing habits together with weak muscles. Treatment includes exercises to strengthen the muscles. For trigger points, therapy involves massage, which is almost always successful.
Invented shortly after Christ walked the Earth, the spirometer is a handy tool for diagnosing the cause of shortness of breath. It can determine the presence of abnormal ventilation, but further tests are often required to eliminate from consideration conditions like asthma, emphysema and bronchitis, among others. Most cases of breathlessness stem from an easily treatable condition, either trigger points, dysfunctional breathing patterns or a combination of the two.
