Spirometer is a medical device that is used to measure the air capacity of the lungs by measuring the volume of air inhaled and exhaled by the lungs. Spirometer generates pneumotachograph which helps to measure lung performance to diagnose and monitor patients with respiratory diseases. Spirometer required for the diagnosis of asthma, chronic obstructive diseases, tuberculosis, cystic fibrosis, silicosis, black lung and other respiratory diseases. Spirometer is used by physicians, payors, research and development industry and patients for personal use. On the basis of types of monitor, spirometer market can be segmented into table-top and handheld. Technological advancement and rise in incidence of chronic disorders are some of the main factors that are driving the spirometer market. Spirometers market can be divided into two categories include volume-measurement devices and flow-measurement devices. Volume-measurement devices include wet spirometer and dry spirometer. Flow-measurement devices include pneumo-tachograph systems and mass flow meter. Some types of spirometer are whole body plethysmograph, fully electronic spirometer, peak flow meter, pneumotachometer, incentive spirometer, tilt-compensated spirometer and windmill-type spirometer. On the basis of application, spirometers market can be segmented into two classes include diagnostic devices and monitoring devices. These devices can be used for different specification and purpose. Spirometers market includes three type of products such as monitoring device for home use, clinical trials device and diagnostic device.
