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.

Giving an accurate prognosis can only be accomplished when the doctor can isolate one's lung capacity and respiratory strength. For this reason, devices of this type are found in virtually all medical facilities, such as hospitals and nursing homes. In numerous instances, they are used on post surgery patients, even if the latter do not have lung conditions. Physicians may still use them to discover whether or not a person's lung capacity has returned to normal after having been placed under anesthesia.

To evaluate the result of a specific medication or medical treatment, doctors often use the aforementioned devices. Spirometers can also indicate whether or not a person's condition is getting better or progressing. If the individual's airflow is decreased or disrupted, the severity of the obstruction can be determined through the use of a spirometer. Therefore, essentially all lung doctors and pulmonologists use equipment of this type.

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 printed on the graph are forwarded to the patient's physician or pulmonologist. The latter can then evaluate the readings and use them to design an appropriate care plan for each individual being treated. The device can also help physicians to determine whether or not drug adjustments may be indicated.

In addition, spirometers are helpful for individuals who have rare disorders of the lung, such as mesothelioma. This is because they can monitor function in both the upper and lower regions of the lung, which is not something other testing devices can do. This particular function allows physicians to zero in on specific issues with ideal 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.
