Spirometer is the name given to the device that is used in order to check the volume of air expired and inspired via the human lungs. The apparatus records the air amount and the rate at which it is breathed in and out within a certain period of time. Spirometers also calculates respiration rates and is therefore referred to as a pressure transducer.
This kind of device is used for different purposes, including tests such as the Pulmonary Function Tests or PFTs. This exam is done as a preliminary step and is helpful in checking the overall health of the lungs. Certain diseases of the lungs can be ruled out through the results of the tests, including bronchitis, emphysema and asthma. Spirometers may also be applied to evaluate the effects of prescriptions and contaminants on this organ, as well as the effectiveness of various treatments.
It was during the 1900s that the first of these devices was developed. This initial device was a dry-bellowed wedge model. It was made by Brodie T G. Prior to this, many other people made unsuccessful attempts at measuring volume of the lungs. Since the 1902 invention by Brodie, the device has improved in many respects. It is now more effective than ever. Other people who were influential in the development of this apparatus: Dubois A B, Compton S D and Woestiijine K P.
The spirometer comes in more than one model. The variation among the different versions is mostly in results. Incentive meter, peak flow, tilt-compensated, pneumotachometers, full electronic, windmill and whole-body plethysmograph are examples of different versions available on the market today.
A whole-body plethysmograph, when compared to other models, is known to provide results that are most accurate when it comes to capacity of lungs. The pneumotachometers are applied to assess the differences of air pressure by way of fine mesh. These structures can also measure the gas flow rates.
Full electronic types, and other electronic spirometers, do not require moving parts or any fine meshes. Instead, they compute airflow rates through channels, rendering the extra moving parts and meshes useless. Furthermore, they do not use ultrasonic transducers or similar methods to measure the speed of airflow.
When it comes to measuring the ability of lungs to inhale and exhale, peak flow devices are employed. Incentive styles can be used to help repair certain functions of the lungs. Wind-mill models, also referred to as spiropet, are mostly used when measuring forced vital capacity. They do not utilize water and may take measurements between 1000 mL and 7000 mL. The tilt-compensated kind is more modern and can be used in a horizontal position while measurements are being taken.
Spirometers is the name given to devices that are commonly used in the field of medicine to assess function of respiratory systems, including the lungs. There are an assortment of models available that provide varying functions and results. The structures are typically used when calculating air volume of lungs. PFTs also involve these structures. The first meter was developed in 1900s, many years after others had attempted to calculate volume of this human organ. Units employed in modern day are quite effective.
