What To Know About A Spirometer

By Paula Barron


Spirometer refers to the device that is applied when checking the volume of air that is inspired and expired by way of the lungs. This apparatus is able to record the amount of air, as well as the rate at which the air is breathed out and in during a certain amount of time. It is capable of calculating respiration rates and because of this, is considered a pressure transducer.

This kind of machine is used in many different medical tests, such as Pulmonary Function Tests or PFTs. The preliminary test is done to check the health of the lungs of patients. There are certain lung disorders, such as bronchitis, emphysema and asthma, which can be ruled out based on the test results. Spirometers are also employed to identify any shortness of breath. This is done by evaluating the effects that contaminants can have on lung function, impact of prescriptions and advancement of disease care.

The original dry-bellowed wedge style of spirometer was first invented during the 1900s. This creation is attributed to a man known as Brodie T. G. Although many other people made unsuccessful attempts to measure the volume of lungs prior to this invention. Since this was developed in 1902, many changes have been made to make the device more effective. Compton S D, Woestijine K P and DuBois A B are just a few other influential figures in the development of this meter.

There is an assortment of spirometer types available. Usually they are different in the results they offer. Full electronic, peak flow, whole body plethysmograph, incentive, windmill and pneumotachometer are examples of this apparatus.

In comparison to other versions, the whole body plethysmograph is believed to offer the most accurate of a volume measurements. This model is used on patients that are placed in a small space. The pneumotachometer is able to detect the differences in pressure. It is mostly used for measuring the gas flow rates.

The fully electronic version, as well as other electronic spirometers, does not require any moving parts or fine meshes. They calculate airflow rates using channels, which renders these extra parts useless. They do not apply ultrasonic transducers and other techniques to track air flow speed.

Incentive models are made to repair function of the lungs. Peak flow styles are ideal for measuring ability to exhale or breath out the air from lungs. Wind-mill meters, also called spiropet spirometers, are primarily used when quantifying forced vital capacity. They cannot, however, use water and might include measurements that fall between 1000 mL to 7000 mL. Tilt-compensated styles are a new version that may be positioned in a horizontal way while the measurements are recorded.

The spirometer is a device used in the field of medicine to measure respiratory function. There are several models available, each one offering various functions and results. Overall, these devices are used to measure volume of air that is exhaled or inhaled by lungs. The apparatus is usually employed for PFTs, Pulmonary Function Tests. The devices were first invented during the nineteenth century, although attempts to create a device with this capability had been made for years prior to the invention.
