Spirometry: testing for assessing and measuring the breath
The Spirometry is the most widely used diagnostic test to detect, taking into account the amount of air that a person can inhale and exhale, pulmonary or respiratory quantities measurable parameters.
Spirometry is the first diagnostic level that allows the doctor to look into the possibility of further study.
The spirometry test is painless, cheap, is repeatable and is designed to detect all respiratory parameters: dynamic lung volumes, vital capacitylung capacity, etc.
Thespirometric examinationalso known as pulmonary function test, is a noninvasive test highly trusted and that allows to detect all the parameters related to lung function. Resorting to it especially restrictive or obstructive diseases patients airway. This examination is also particularly suitable for regular smokers with cardiovascular disease.
The 5 most important parameters that are detected during spirometry
Generally speaking we can say that the Spirometry reliably returns the conditions of lung function. In particular it is able to detect the following parameters:
1 – vital capacity (HP): indicates the volume of air that a person can issue in a slow exhalation and ceiling, starting from a complete inspiration. The average healthy adult vital capacity is 4.5 liters of air.
2 – forced vital capacity (FVC): indicates the maximum volume of air that can be ejected in a forced expiration, starting from a complete inspiration.
3 – maximum Expiratory Volume (FEV1): indicates the maximum volume of air that can be exhaled after an inhalation ceiling.
4 – relationship between maximum Expiratory Volume and forced vital capacity (FEV1/FVC): this report is very important to distinguish any obstructive problem from a restrictive.
5 – peak expiratory flow (PEF): indicates the maximum speed at which the airflow can be expelled from the respiratory tract starting from a full inspiration.
The FEV1/FVC ratio, described in section 4, in normal adult patients varies between 70% and 80%; a value lower than 70% means that the respiratory system has a obstructive deficit and that therefore there is a high probability that the individual submitted to spirometry test is affected by chronic obstructive pulmonary disease obstructive pulmonary disease (COPD).
Why is it important to spirometry
If the Spirometry to run as soon as the first symptoms appear related to a disorder of the respiratory system, it shall supply the doctor very important parameters both for the elaboration of a early diagnosis both in terms of therapeutic process the patient must observe. The use of this non-invasive diagnostic test It is also very important to monitor any ongoing respiratory illness and to verify the effectiveness of the therapeutic process undertaken.
The execution of spirometric examination your family doctor may be required if your patient has respiratory disorders (chest pain, production of sputum, persistent cough, etc.), or if the patient will be subjected to laboratory tests that have shown values outside the normal range.
It must be said in this regard that there are many diseases that can affect the respiratory system. Among the most popular include the following:
asthma: this is an inflammatory disease characterized by reversible airway obstruction usually underneath; It can either be allergic not allergic;
- chronic obstructive pulmonary diseaseDisease (COPD): it is a progressive lung disease characterized by bronchial obstruction not fully reversible;
- thechronic bronchitis: this is a chronic condition affecting the respiratory system; It is very debilitating and is characterized by persistent cough and excessive mucus production and pus. Acute bronchitis can occur as a complication of a common cold or a seasonal flu;
- Interstitial Pulmonary Fibrosis: this is a chronic disease characterized by the progressive transformation of the fabric of the lungs, which is the pulmonary parenchyma, inscar tissue. Fibrosis is a disease is not reversible, so the only possible therapeutic path aims to improve the patient's quality of life;
- pulmonary emphysema: this is a disease that affects the alveoli, which are small pouches that hold the air in your lungs. They reduce gradually its functionality, making the subject more and more short of breath. Emphysema, remember, fall under the category of obstructive lung diseases. One of the main causes which causes pulmonary emphysema is the smoking habit.
- pneumonia: this is ainflammatory disease hitting the end part of the lungs. It can be determined from pathogenic microorganisms (such as bacteria or viruses), or from an injury. When it contracts pneumonia lung tissue fills with pusand other liquids, causing difficulty breathing, cough and fever.
Spirometry, remember, no delivery exclusively to diagnose bronchopulmonary diseases suspected or to keep them under control in therapeutic phase, but also to check eligibility for the practice of athletic activities, to detect any risks before a surgery and for the screening individuals who have a high level of risk of contracting an illness of the respiratory system.
