Spirometers are devices that are used to measure breathing functions within the lungs. This medical device is used to test the breathing capacity of the lungs. Patients are asked to breathe in a tube that is connected to this device. Patients that are receiving care for pulmonary conditions use this device to monitor their condition.

A variety of tests are conducted utilizing this tool. This is a device that can detect subtle changes of air pressure. The device is able to detect negative changes regarding breathing capacity. These devices are able to produce a chart that demonstrates the airflow of the patient. The graphical chart allows the doctor to see the amount of air the patient can inhale and exhale.

The original device was a cylinder that was suspended into water and moved up and down when the patient breathed. When the cylinder moved, a pen would graph the results on paper. A technician would read the results and determine the lung capacity. There are several kinds of pressure related devices that are used to measure breathing.

Technicians obtain specialized training to administer this test. When individuals take this test for the first time, they are assessed by a technician. After they are made to be familiar with the device, the test is given and then the technician collects the data. There are three breathing patterns that are tested to obtain a range of values in order to determine the patient's health.

This device does not measure total lung capacity. It measures the amount of air that comes in and out of the lungs. Individuals who have severe bronchial issues may still have a high lung volume but the test may not reflect this because only a small amount of air goes through the bronchial tubes. There are other devices that are used to test lung volume.

A doctor can determine if there is a problem with the airways that is causing certain breathing problems. They can determine what course of treatment to take. In most cases certain medication will be prescribed to help breathing become easier for the patient. This test can diagnose certain illnesses like asthma and other conditions. There are chronic diseases which can be detected with this device.

People with chronic lung disorders are often tested utilizing this test. This device is highly effective in diagnosing breathing ailments. Chronic diseases are monitored and treated using these tests. This test is performed over a series of intervals to treat chronic illnesses. The doctor will monitor changes in breathing and prescribed medication if symptoms worsen.

Spirometers are very important tests for people with breathing problems to have. Individuals having this test for the first time need to be prepared for the test. They will need to have comfortable, loose fitting clothes that do not make breathing uncomfortable. Patients are also instructed no to eat heavy meals right before the test. It is important for patients to follow certain instructions so the technician gets accurate results.
