Difficulty breathing is a common complaint and a conundrum for the diagnostician. A spirometer is a type of pulmonary function monitor PFM), a device that measures the volume of air breathed in and out by the lungs. The printed output from the device will detect two different kinds of atypical ventilation patterns, restrictive and obstructive. There are several types of spirometers that use different approaches for measuring air movement (ultrasound, water gauge, pressure transducers). Today, there are also standalone and computer-based devices.
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.
Along with instrumentation, there are a half dozen or more so-called "red flag" symptoms and signs that may herald a serious lung condition. These include persistent pallor and fatigue, swollen ankles, a chronic wheeze or cough, having a hard time breathing when lying flat, pain worsening with activity, or any other persistent or strange symptoms. A history of working in an environment where there is asbestos, wood dust, hazardous chemical fumes or in a coal mine might also contribute to a lung disorder.
Asthma, a chronic disease of the airways, is somewhat more serious. According to the Centers for Disease Control in Atlanta, Georgia, 18.9 million non-institutionalized adults have asthma at any one time. This represents 8.2 percent of that population.
Once serious causes of breathlessness have been eliminated from the differential diagnosis, many cases can be traced to one of two simple and easily remedied causes, either trigger points, also known as muscle knots, or dysfunctional respiratory habits and weak muscles. The treatment for both is safe, cost-free and easily performed by the patient. It involves a program of exercise and trigger point massage.
The spirometer is a device that has been in use for nearly two thousand years for the detection of breathlessness. It can identify whether breathlessness is present, but further investigations are required to rule out serious conditions like asthma. Once sinister problems have been ruled out, the cause of shortness of breath is most likely a combination of trigger points and dysfunctional breathing technique. This can be easily remedied with a regime of trigger point massage and breathing exercises.
