Spirometers is the name of a special devices that are applied to check the air volume inhaled and exhaled via the human lungs. This device also records the amount of air and the rate at which this air is breathed within a certain time. It handles calculations of respiration rates and as a result of this, is referred to as a pressure transducer.
The machine is employed for many different medical exams, including PFTs or Pulmonary Function Tests. The PFT is a preliminary test that is done in order to check overall lung health. There are many diseases that can be ruled out just by looking at the PFT results, such as: bronchitis, asthma and emphysema. Spirometers can be used when checking the effectiveness of prescriptions and treatments too.
The first unit of this type was developed in the 1900s. The creator of this dry-bellowed wedge device was Brodie TG. Before this invention by Brodie, other attempts had been made to develop a structure that was able to check the volume of lungs. Since the wedge model invented in 1902, this type of machine has evolved and improved in many ways. It is now more effective than ever. Others who contributed to the development of this structure: Compton SD, Woestijine JP and DuBois AB.
