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.

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.

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.

When spirometers are used for the aforementioned testing, the length of time it takes to complete the test will vary from a few minutes to an hour. This depends on the data for which the doctor is looking. In most cases, the test does not exceed one hour. Because of the numerous advantages they provide, this kind of device will likely remain a popular diagnostic tool with many professionals in the medical field, such as doctors or pulmonologists.
