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.
This type of machine is employed for several different tests, including PFTs or Pulmonary Function Tests. The PFT is done as a preliminary exam to check lung health of patients. There are some diseases of this organ, such as asthma, emphysema and bronchitis, that can be ruled out based on these test results. Spirometers may be used as a way to help evaluate effects of contaminants and prescriptions on the lungs and impact of treatment for medical conditions.
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.
Spirometers are available in different models. Most variation between the versions lies in results. Whole-body plethysmograph, full electronic, incentive meter, peak flow, windmill, tilt-compensated and pneumotachometers are some examples of available models.
In comparison to other modern versions, whole-body plethysmographs are known to provide the most accurate measurements of lung volume. The pneumotachometer is able to detect the difference in air pressure by utilizing a fine mesh. This is why the device is primarily used when measuring the gas flow rates.
The full electronic kinds, as well as other electronic versions, do not include fine meshes or moving parts. However, they are able to compute the rate of airflow by way of channels. Extra moving parts, included meshes, are not needed. Likewise, they do not need to apply ultrasonic transducers or other techniques to measure airflow speed.
Peak flow kinds are good for use at measuring ability to inhale or exhale using via the lungs. Incentive models are used to do repair work on lung functions. Wind mill styles, or spiropet spirometers, are often used to measure the forced vital capacity. They do not use water and may include measurements between 7000 and 1000 mL. Tilt-compensated models are more modern kinds that allow for horizontal positioning during the measurement process.
Spirometers are units mostly employed in the medical field to measure function of human lungs and respiratory systems. Numerous models can be used and each one offers its own functions and results. Generally, structures are used to calculate the volume of air that lungs take in and let out. They are used for PFTs as well. Meters were first made in the early 1900s, but many attempts at testing lung capacity were made prior to development of this apparatus. The units used in modern times are very effective.
