The respiration functional screening is a series of tests used to evaluate the function of the respiratory system, and specifically the function of lungs and the respiratory tract. The goal is to measure various factors related to respiration, such as the air volume inhaled and exhaled, the respiration speed and the body's ability to carry oxygen and remove carbon dioxide.
The main tests included in the respiration functional screening are the following:
Spirometry: The most common and basic rest, measuring various indexes of respiratory function, such as the volume of air exhaled in 1 second (FEV1), the total volume that can be exhaled (FVC) and other parameters.
Oxymetry (oxygen saturation measurement): Measures the blood's oxygen saturation, that is, the percentage of oxygen carried in the blood via the lungs.
Air flow measurement: Tests how quickly and easily the person can breathe, often with the use of a strong and fast exhalation mechanism.
Test after administration of bronchodilators. Tests the reaction of the respiratory system to medication expanding the air ducts (bronchodilators), helping diagnose conditions such as asthma or COPD.
Measurement of exhaled air volume (Peak Flow): Measurement of the speed of air one can exhale with maximum effort, often used to monitor patients with asthma.
Spirometry
Spirometry is a test which is used to measure lung function. It is usually used to diagnose or monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD) and other respiratory disorders.
During spirometry, the patient is asked to breath strongly in a special tube (spirometer) which logs various parameters, such as the volume of air inhaled or exhaled and the speed at which it must be done. These results help doctors evaluate the lungs’ capacity to carry oxygen in the blood and remove carbon dioxide, as well as evaluate the extent of any respiratory issues.
Spirometry is one of the basic tools used to evaluate and monitor respiratory conditions.
