Spirometry equipment was designed for the purpose of measuring and evaluating an individual's breathing and lung function. Spirometers are used more often than any other type of pulmonary function testing device. Such equipment specifically measures the volume of air and the rate at which it flows when a person completes one full respiration. The latter refers to the entire cycle of inhaling and exhaling.

A spirometer plays a vital role in the diagnosis of numerous health issues, such as cystic fibrosis, emphysema, asthma, obstructive pulmonary disease, lung cancer, pulmonary fibrosis and a broad range of other lung disorders. There are several models from which a health care professional can choose, but most feature a graph that tracks the individual's spirograms, which is the medical term for respiration measurements.

Patients who have various types of respiratory conditions may benefit considerably from the use of a spirometer. The latter were first invented in the mid-1800s. However, contemporary tools of this kind are quite different from those utilized during the nineteenth century.

Such devices are also utilized to anticipate future health issues for which certain individuals are at risk. The determination of respiratory capacity and strength is imperative if a medical practitioner is to predict potential future problems in some patients. For this reason, equipment of this type is found in essentially every medical facility. In surgical hospitals, spirometers are frequently used to test patients' post surgery lung capacity.

Spirometry equipment can also help medical practitioners to track the progress of a certain disease or the effectiveness of a specific treatment. It can also be used to evaluate whether or not a lung condition is restricting or disrupting the person's flow of air. Essentially all pulmonologists use such equipment daily.

Disposable tubing, a mouthpiece, and a testing box are the three components that make up the device. The patient is instructed to inhale and exhale through the tube in a normal manner and his or her breathing patterns are tracked and displayed. It sometimes becomes necessary to administer multiple tests to acquire an accurate reading. The procedure itself may take as long as a full hour or it may last only several minutes.

The amount of time necessary to complete breathing evaluation with this type of equipment will depend on the kind of information the attending physician is seeking. The results of the completed test are forwarded to the patient's pulmonologist who can make the appropriate evaluations and recommend proper treatment. Such information is also highly helpful with regard to tracking the effectiveness of specific treatments or medications.

Doctors who specialize in disorders of the lung often suggest regular testing for their patients in order to efficiently monitor their progress. Such equipment is particularly helpful for individuals with rare illnesses, such as mesothelioma. This is because, unlike many other devices, a spirometer is able to measure lung function in both the upper and lower lobes, which allows the physician to pinpoint specific problem areas. Due to the many benefits they offer, spirometers will likely remain an integral part of the diagnosing process for lung patients throughout the world.
