A spirometer is a device used for measuring respiration flow rates. It measures the volume of expired and inspired air by the lungs. The device records both the rate and amount of air that is inhaled and exhaled over a given period of time. They are used in hospitals to improve the functioning of lungs of patients especially the incentive spirometer.
Some spirometers function on similar principles as gas meters. Normally, a soda cylinder is attached on the device to absorb carbon monoxide gas. Kymograph traces are generated for recording changes in the entire gas volumes. From these records, vital capacities, ventilation rates, breathing rates, and the tidal volumes may be calculated. General declines on the graphs can be used to calculate oxygen uptakes.
Primary forced volume vital capacity tests are different depending on the equipment employed. During the operation, patients are asked to take the deepest breaths they can afford and then exhale as forcefully as possible into the detector. Patients are also needed to exhale into the devices as long as they can. The most preferable period is at least 6 seconds. Nose clips could be utilized to prevent air from getting out through the noses whereas filter mouthpieces stop the possibility of microorganisms spreading.
Spirometers play fundamental roles in the PFTs mostly abbreviated as pulmonary function tests. These tests act as preliminary tests for the health status of the lungs of patients. Lung conditions like emphysema, asthma, and bronchitis can be diagnosed using these devices. Medical experts can use spirometers for many applications, including determining the existence of diseases and analyzing the effects of contaminant materials on the activities of the lungs.
Some tests done using spirometers demand both the efforts and cooperation of the persons under test. This is to ensure accurate results and that the patients can do the necessary maneuvers that come with the tests. The patients are likewise expected to follow necessary instructions, hence because of this, some devices are not suitable for use on persons who are unconscious or heavily sedated. It is advisable that lung functionality test for such individuals be done using other techniques.
There are several kinds of spirometers like incentive, wind mill type, body pneumotachometer, and fully electronic spirometers. Pneumotachometer spirometers are employed in measurement of the rate of gas flow by detecting changes in pressure across fine lattices. The key advantage here is the ability of a subject to breath in fresh air during operation.
The benefit with some spirometers is their portability and presence of sensors which gauge the air speed. They are disposable hence preventing possible spreading of ailments. Additional electronic parts may assist the spirometers generate loops and volume curves. Absence of real time measurements and difficulty in calibration of results are the main disadvantages of spirometers. If the interior surfaces are kept unclean, bacteria may thrive there.
Getting a spirometer of commendable quality is not the greatest issue. This is so because there are numerous stores that specialize in them. In case local stores are hard to come by, online stores could be of help. Doing some research before purchasing is advisable.
