Founded in 1980 and based in Rome, Italy, COSMED started manufacturing portable spirometers and pulmonary function testing equipment. In the nineties, the company introduced new systems for gas exchange measurements and patented the first portable system with telemetric data transmission for the measurement of metabolic parameters during field-testing.
A spirometer is the main piece of equipment used for basic Pulmonary Function Tests (PFTs). Lung diseases such as asthma, bronchitis, and emphysema may be ruled out from the tests. In addition, a spirometer often is used for finding the cause of shortness of breath, assessing the effect of contaminants on lung function, the effect of medication ...
The basic forced volume vital capacity (FVC) test varies slightly depending on the equipment used. It can be in the form of either closed or open circuit. Regardless of differences in testing procedure providers are recommended to follow the ATS/ERS Standardisation of Spirometry. The standard procedure ensures an accurate and objectively ...
Pulmonary function testing is a safe procedure; however, there is cause for concern regarding untoward reactions and the value of the test data should be weighed against potential hazards. Some complications include dizziness, shortness of breath, coughing, pneumothorax, and inducing an asthma attack. [13] [14]
Handheld devices displaying the measurement achieved in centimetres of water pressure (cmH 2 O) and the pressure trace created, allow quick patient testing away from the traditional pulmonary laboratory and are useful for ward-based, out-patient and preoperative assessment, as well as for use by pulmonologists and physiotherapists.
Impulse oscillometry (IOS), also known as respiratory oscillometry, forced oscillatory technique (FOT), or just oscillometry, is a non-invasive lung function test that measures the mechanical properties of the respiratory system, particularly the upper and intrathoracic airways, lung tissue and chest wall, usually during the patient's tidal breathing (the way someone breathes when they are ...
The measurement of peak expiratory flow was pioneered by Martin Wright, who produced the first meter specifically designed to measure this index of lung function. Since the original design of instrument was introduced in the late 1950s, and the subsequent development of a more portable, lower cost version (the "Mini-Wright" peak flow meter ...
