In the health care field, a lot of physicians use spirometers. These are special machines that are designed to check air volume of lungs. Essentially, the devices test the total amount of air that is being inhaled and exhaled by way of the lungs. This unit is also made to record the rate and total of air that is breathed in a set amount of time. It offers information on the respiration rates and may be called a pressure transducer.
This type of device is employed for numerous medical tests, including PFTs, also called Pulmonary Function Tests. This preliminary exam is done to test the health of the lungs. There are numerous diseases of this organ that can be ruled out based on the results of this test, including bronchitis, asthma and emphysema. Spirometers are also used to identify the effects that prescriptions and disease care have on lungs.
The first of such structures was created during the 1900s. It was a dry-bellowed wedge version designed by Brodie TG. Prior to this development, unsuccessful attempts had been made to create a device that measure lung volume. Since this invention in 1902, the device has improved in many respects and is now highly effective. Other people who were involved in the development of this apparatus include DuBois AB, Woestijine JP and Compton SD.
A lot of spirometer models are available and used in modern times. Typically their differences are in results they produce. Peak flow, pneumotachometer, windmill, full electronic, incentive meter, whole body plethysmograph and tilt-compensated are just a few examples of the versions used.
When compared to other modern versions on the market, the whole body plethysmograph is known as the highest in accuracy of volume measurements. This type is used on people who are placed in a small space. The pneumotachometer is able to detect difference in pressure. This is possible via fine mesh. Pneumotachometers are also employed to measure the gas flow rates.
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.
Incentive models are mostly used to repair function of lungs. Peak flow versions are good for measuring ability of one to breath the air out, or exhale. Windmill, also called spiropet, meters are usually applied to measure forced vital capacity. Still, they do not use water. Tilt-compensated styles are more modern and can be in a horizontal position when measurements are being recorded.
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.
