Spirometers And How They Work

By Debra Cooley


Individuals who are suffering from respiratory conditions often benefit greatly from a medical diagnostic machine referred to as a spirometer. The latter is designed to take a highly detailed reading of a patient's breathing function. This is particularly advantageous to those suffering from disorders of the lung, including emphysema or asthma. Spirometers measure how much air volume one is able to inhale, as well as the strength of his or her respirations.

Machines of this type were used since the early 1900s, and are frequently relied on to assist diagnosticians to evaluate lung problems. Digital models were eventually created as a result of perfected medical technology. Even though not all units provide digital readings, most contemporary models boast this technology. Healthcare practitioners can select from various barometer models when performing such tests.

Isolating a patient's lung capacity and respiratory strength plays an important role in the accuracy of the prognosis. This is why devices of this type are used in virtually all medical facilities, including acute care hospitals or long-term care establishments. They are also frequently utilized by doctors who want to discover if those who have recently been operated on and are awakening from anesthesia are returning to normal lung function.

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.

One's pulmonologist or physician then reads the printed results. Practitioners can then evaluate the readings and design a proper plan of care for the person. Machines of this kind also help physicians to discover whether or not drug adjustments are required.

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.

It can take anywhere from an hour to merely a few minutes to test a person's lung capacity with a spirometer. The amount of time necessary will depend on what kind of data the physician requires. However, it rarely takes longer than an hour to measure lung function with such a machine. Due to the numerous benefits they provide, spirometers will likely remain a favorite diagnostic tool among physicians, pulmonologists, and other medical practitioners.
