Essential Facts About How Spirometers Work

By Debra Cooley


A medical diagnostic tool referred to as a spirometer frequently benefits patients suffering from respiratory conditions. Spirometers were created to measure the breathing function of humans in a very detailed way. This is particularly advantageous to those afflicted with asthma, emphysema, or other respiratory disorders. Device of this kind measure the force of one's respirations, and the volume of air he or she can inhale.

Used since the beginning of the nineteenth century, machines of this type are virtually always relied on to help diagnose lung problems. The technology behind them has been slowly perfected until a digital model was finally created. Although not all models offer digital readings, most modern devices of this type feature digital technology. Physicians can choose from a variety of spirometer units when performing tests of this type.

Isolating one's respiratory strength and lung capacity plays a vital role in prognosis accuracy. This is why machines of this kind are found in essentially all medical establishments, such as nursing homes and hospitals. In many cases, they are used post-surgery, even on those who do not suffer from respiratory disorders. They are frequently used by physicians who want to find out whether or not an individual's lung capacity has returned to normal following the administration of anesthesia.

Physicians also use such devices to evaluate the results of specific medical treatments or medications. Spirometers can also provide a way for doctors to discover whether or not and individual's disorder is worsening or getting better. If the person's air flow is disrupted or decreased, a spirometer can evaluate the severity of the obstruction. For this reason, virtually all pulmonologists and doctors use such equipment.

Units of this kind are usually made from tubing that is disposable. The latter is attached to the machine and its mouthpiece. The patient must typically tighten his or her lips around the mouthpiece and then simply breathe out and in normally. A digital graph will eventually display the person's respiratory patterns and lung function.

The results are printed and given to the person's pulmonologist or physician. Such professionals can then evaluate the results and create an appropriate plan of care for the patient. Devices of this type also help doctors to determine whether or not medication adjustments are necessary.

In addition, those afflicted with rare lung disorders, including mesothelioma, can benefit from testing completed with spirometers. This is because such devices can do certain things other diagnostic tools cannot, such as monitoring both the lower and upper pulmonary regions. This specific benefit allows the pulmonologist or physician to zero in on specific problems with precise accuracy.

Testing with spirometers can take anywhere from several minutes to an hour. This will depend on the type of data the doctor wishes to retrieve. However, it rarely takes longer than sixty minutes to evaluate lung function with such a device. Because of the multi benefits they offer, such machines will probably remain a popular diagnostic tools among pulmonologists, physicians and other professionals in the health care field.
