Measuring Breathlessness With A Spirometer

By Serena Price


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.

Lung function tests are utilized to eliminate the presence of serious pulmonary conditions such as asthma, emphysema and bronchitis. They are also performed to assess the influence on the lungs of medications or ambient contaminants, to help determine the cause of breathlessness and to evaluate the progress of treatments. Lung function tests are also performed before surgery on the lungs to take benchmark measurements of lung activity.

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.

Most causes of shortness of breath are benign and easily reversible. First, it is essential to rule out more sinister causes. The Mayo Clinic defines shortness of breath as a severe tightening of the chest and a sensation of being suffocated. There may be a single episode or there may be a pattern of episodes.

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 any serious cause has been ruled out, most cases of breathlessness are related to one of two causes, bad respiratory habits and weak muscles; or trigger points, or muscle knots. These are both minor and easily treatable. The treatment is safe, free and almost fun. It consists of identifying and massaging trigger points.

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.
