Spirometers are apparatus used to measure the volume of air inspired and expired by lungs. This process of measuring and determining lung functions is referred to as spirometry. It tries to determine the volume and speed of the air that gets in and out of the lungs. The equipment makes a record of these figures over a given period of time.
Spirometer are among the devices used for basic PFTs pulmonary function tests. It is used in preliminary tests in patients with lung conditions. Spirometry is a tool used to generate pneumotachographs which help in the assessment of various lung conditions. Some of the conditions tested include asthma, cystic fibrosis, bronchitis, emphysema, COPD, and pulmonary fibrosis.
Functions of spirometry are many running from measurement to treatment of conditions. It helps in management of asthma and its diagnosis. Respiratory diseases in people who experience symptoms such as shortness in breath may be detected. Such illnesses can also be differentiated whether they are being caused by cardiac disease or not. It also determines natural history of a disease in respiratory conditions. Restrictive and obstructive lung disease can be distinguished with ease.
The device applied causes differences in forced volume vital capacities. The procedures for employing this equipment require individuals to breathe in and out as deep as they can manage. They then exhale into a sensor with a lot of force from lungs. The exhalation process needs to last as long a...
