What is a spirometer?
Spirometer is a device used to measure the breath flow in and out of the lungs. This device is used in the medical testing procedure known as spirometry in which the patient inaches and out of the tube connected to the spirometer to assess the lung function. Many people who receive lung conditions have interact with a spirometer at some point in their lives. Several different methods can be used to create a spirometer. The aim is to create a device that is very sensitive to air pressure changes so that it can measure the fineness of air flow into AZ lungs. Spirometers produce a graphical output with a stream of air along one axis and time along the other. This allows the doctor not only to see how much air the patient breathes in and out, but also the time. The maximum flow value can also be obtained by searching for the highest point on the graph.
The original spirometer design was a roller suspension in water that could move up and down when the patient exhaled. When the roller moved, he pushedThe pen connected to graphic paper and created a graph that can be read after the test. A number of other pressure sensitive devices can be used for spirometry, although the water -based method is still used in some hospitals.
work with a spirometer has some practice. When patients first use devices, they are often given a test run to know what the experience is before the data assembly. At least three breathing cycles are completed on the spirometer to obtain the range of values that can be average to reflect the patient's condition. If the numbers differ wildly, it may be a sign that one or more tests were wrong and need to be repeated.
Spirometry is strongly dependent on the patient's cooperation and it is important to realize the total lung volume, but only the amount of air that can be pushed in and out of the lungs. Someone with a heavy bronchial obstruction can have a very high OBThe lungs, but this would not be reflected in the spirit of spirit, because only a limited amount of air could be forced during bronchial pipes. Other tests can be used to test the lung volume, and a full battery of lung function or PFT tests can be used to assess the lung function as a whole.
