Spirometers And How They Work

By Debra Cooley


Patients afflicted with respiratory disorders frequently benefit from the use of a medical testing device called a spirometer. Spirometers are designed to measure a person's breathing function in a highly detailed manner. This is especially helpful to individuals suffering from respiratory problems such as asthma or emphysema. Devices of this type measure the volume of air one is able to inhale, as well as the force of his or her respirations.

In the use since the dawn of the 19th century, devices of this kind are essentially always used to assist doctors to make accurate diagnoses of lung problems. The science used to create such devices has been perfected resulting in the now commonly used digitized models. Although not all devices provide digital readings, most contemporary humans have this feature. Practitioners can choose from various models when performing the aforementioned tests.

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.

Such units are made from disposable tubing that is attached to a mouthpiece and a measuring device. The person must usually close his or her lips snugly around the mouthpiece and then proceed to breathe in and out in a normal pattern. His or her respiratory patterns are then recorded digitally and displayed on a graph.

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.

Additionally, spirometers are beneficial for those who have rare lung conditions, such as mesothelioma. This is due to the fact that they can monitor both the upper and lower function of the lungs, the latter of which is not something other diagnostic machines can do. This specific function lets doctors identify certain disorders with extreme 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.
