The Key Features Of Spirometers

By Tonia Merritt


In the medical field, many professionals utilize spirometers. These special machines are primarily employed for the purpose of checking air volume. That is, the total volume of air that is exhaled and inhaled through the lungs of a person. The apparatus is also designed to record the total of air, and the rate, breathed in a specific duration of time. It provides respiration rates and is also known as a pressure transducer.

This machine is applied for a variety of different tests in the medical world, including Pulmonary Function Tests or PFTs. This is a preliminary exam that is used to check overall health of lungs. There are various diseases of the organ that are ruled out solely based on test results, such as asthma, emphysema and bronchitis. Spirometers can also be utilized to check the impact of disease treatments and prescriptions.

The 1900s saw the first of these devices. It was made by Brodie TG and known as a dry-bellowed wedge model. Prior to this, other attempts were made to create a unit that could check lung volume. Since this wedge model in 1902, the machine has undergone much improvement. It is not very effective. DuBois AB, Compton SD and Woestijine JP are just some of the other individuals who had a role in the development of this apparatus.

There are multiple versions of spirometers available for use. Often they differ the most in the results that they offer. Full electronic, peak flow, windmill, whole body plethysmograph, pneumotachometer, incentive meter and tilt-compensated are just some examples of the different models used in modern times.

The whole body plethysmograph, in comparison to other modern kinds, is deemed the most precise in terms of volume measurements. This particular kind is used on individuals while they are placed in small rooms. The pneumotachometer is capable of detecting any difference in pressure. This is done over fine mesh and the reason why it is also used to measure gas flow rates as well.

The full electronic types, and other electronic versions, do not need or having moving parts or fine meshes. Instead, they work by computing airflow rates based on channels. This technique renders the added parts useless. Furthermore, no equipment or techniques are applied to measure airflow speed.

The incentive models are used to repair lung function. Peak flow kinds are best for measuring the ability of a person to exhale, breath air out of their lungs. Windmill meters, also known as spiropet, are typically employed to calculate the forced vital capacity. However, they do not utilize water and may feature measurements from one to several mL. Tilt-compensated versions are considered newer and can be used horizontally while measurements are taken.

Spirometers are used in the health care industry as a way to test the respiratory function of the human lungs. There are a variety of versions that can be used and each one has its own components and results. Overall, the apparatus is effective when it comes to measuring the air volume that is inhaled or exhaled. This device is often employed during Pulmonary Function Tests. The first meter of this type was developed in the nineteenth century after many unsuccessful attempts were made to create a machine that tests lung function.
