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.
The 1900s saw the first of these structures. The dry-bellowed wedge model was the first of these devices developed by Brodie T G in 1902. Before this development, many others had attempted to measure the volume of the lungs to no avail. The device made by Brodie has evolved in many ways since original development and now is extremely effective. Others who played a role in creation of this machine: Woestiijine K P, Compton S D and Dubois A B.
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.
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.
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.
