Basic Information Related To Spirometers

By Myrtle Cash


Spirometers are devices designed for the purpose of tracking the activity of the lung. More specifically, these structures are capable of tracking how much hair is taken in and let out. Typically this information is recorded. The units can also be used for calculating respiration rates, which is why they are often described as pressure transducers.

These units are employed for many different purposes. They are often used as part of Pulmonary Functions Tests, also known as PFTs. This preliminary test is done to assess the overall health of the human lungs. There are specific diseases that can be ruled out based solely on the results of these tests, such as: asthma, emphysema and bronchitis. Spirometers are often used to evaluate the impact of certain treatments and effects of contaminants and prescription drugs.

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.

There are several different versions of these machines available for use. Typically their variation is in the results that they offer. Full electronic, peak flow, windmill, pneumotachometers, incentive meter, tilt-compensated and whole-body plethysmograph are just some examples of the numerous models.

Whole-body plethysmographs, compared to other such devices, are known for providing highly accurate results related to lung volume capacity. Pneumotachometers can detect differences in air pressure through use of fine mesh. The device is often used to measure flow rates of gas.

Full electronic styles, and other electronic kinds, do not feature moving parts or fine meshes. This is because they can compute rat of airflow through channels. The meshes and moving parts are not necessary. Additionally, they do not need ultrasonic transducers or other methods in order to measure airflow speed.

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.
