  A spirometer is a diagnostic device that measures the amount of air you can breathe in and out and the time it takes you to breathe out completely after you take a deep breath. […] To find out if you have emphysema, your doctor or other healthcare professional asks about your medical and family history, smoking, and whether you’re often around other lung irritants. Your healthcare professional does a physical exam that includes listening to your lungs. You may have imaging tests, lung function tests and lab tests. […] Spirometry is the most common test to diagnose emphysema. During spirometry you blow into a large tube connected to a small machine. This measures how much air your lungs can hold and how fast you can blow the air out of your lungs. Spirometry tells how much airflow is limited.

  A diagnosis of emphysema will begin with a thorough medical history and physical exam. During the physical examination, patients with advanced cases of emphysema often have larger than average chests (due to abnormal lung expansion); rounded finger tips; faint breathing noises; low oxygen levels in the blood (hypoxia); and high levels of carbon dioxide in the blood (hypercarbia). […] If certain characteristics or symptoms are present, additional diagnostic tests will be ordered to confirm the diagnosis. To determine the health of ones lungs, a pulmonologist may recommend pulmonary functions tests (PFTs); a chest X-ray; a CT scan of the chest; and/or blood count testing to confirm the diagnosis. In a person with emphysema, pulmonary function tests will show lower than average air intake and circulation; the chest X-ray will reveal larger than average lungs; the CT scan will display images of damaged pockets of the lungs; and the blood count will indicate an elevated number of red blood cells.

  The symptoms of emphysema and other chronic obstructive pulmonary diseases (COPD) develop slowly. Most people don’t realize they have the condition until these symptoms worsen. […] Doctors use a variety of tests to diagnose emphysema. […] One of the best COPD diagnostic tools is a lung function test called spirometry. […] Your doctor may also: […] Order an arterial blood gas test to measure the amount of oxygen and other gases in your bloodstream. […] Use a stethoscope to listen to your lungs as you breathe, but sometimes lungs sound normal even in people who have emphysema. […] Order x-rays or a CT scan of your lungs. While these can prove helpful, lungs may look normal even with emphysema present, especially with an x-ray image. That’s why doctors consider spirometry the most reliable tool for diagnosing COPD.

  Spirometry documents the presence of chronic airflow obstruction. Forced vital capacity (FVC) measurement provides data for assessment of expiratory airflow. Measurements of FVC, forced expiratory volume in 1 second (FEV1/FVC), show the presence and degree of airflow obstruction. […] Carbon monoxide diffusing capacity (dlco) testing is performed in conjunction with spirometry to assist in differentiating emphysema from asthma and chronic bronchitis. In emphysema, the dlco is usually decreased because of the loss of surface area of the alveolar-capillary membrane. The combination of a decreased FVC, a decreased FEV1, a decreased dlco, and increased lung volumes and capacities is generally diagnostic of emphysema. […] High-resolution CT may be useful in the diagnosis of subclinical or mild emphysema. High-resolution CT scanners furnish images of low-attenuation lesions associated with emphysema.

  https://bestpractice.bmj.com/topics/en-gb/7/diagnosis-approach

  Spirometry is required to make the diagnosis of COPD and is also used for monitoring disease progress. […] It is the most reproducible and objective measure of airflow limitation. Spirometry should be performed after administering an adequate dose of at least one short-acting inhaled bronchodilator to minimise variability. […] Patients with COPD have a distinctive pattern seen on spirometry, with a reduced FEV and FEV/FVC ratio. The presence of airflow limitation is defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria as a post-bronchodilator FEV/FVC 0.7. […] Chest x-ray (CXR) is rarely diagnostic but should be performed to exclude other diagnoses and to assess for the presence of significant comorbidities. […] Pulse oximetry screens for hypoxia and should be performed in all patients presenting with signs of respiratory failure or right heart failure. If peripheral arterial oxygen saturation is 92%, then arterial blood gases should be measured.

• #1 Emphysema – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK482217/

  Emphysema is a pathological diagnosis, and routine laboratory and radiographic studies are not typically indicated. The mainstay of diagnosis is pulmonary function testing (PFT), particularly spirometry. In cases of abnormal values, a postbronchodilator test may be performed. COPD is either partially reversible or irreversible with a bronchodilator, and postbronchodilator forced expiratory volume in the first second over forced vital capacity (FEV1/FVC) of less than 0.07 is diagnostic.[10][11][12][13] […] Young individuals presenting with symptoms of emphysema should be tested for alpha-1 antitrypsin deficiency. Early detection can guide treatment and help prevent further lung damage.

  Pulmonary emphysema is defined as the „abnormal permanent enlargement of the airspaces distal to the terminal bronchioles accompanied by destruction of the alveolar wall. Emphysema is best evaluated on CT, although indirect signs may be noticed on conventional radiography in a proportion of cases. […] CT is the modality of choice for detecting emphysema; HRCT chest is particularly effective. It should be noted, however, that there is a relatively poor correlation between autopsy-proven emphysema, pulmonary function test abnormalities and CT with 20% of pathology-proven cases not being evident on CT and 40% of patients with abnormal CT having normal pulmonary function tests. […] CT is able to discriminate between centrilobular, panlobular, and paraseptal emphysema. In all three subtypes, the emphysematous spaces are not bounded by any visible wall.

  All individuals with COPD regardless of age or ethnicity should be tested for AATD. Of the approximately 75 different alleles for alpha1-antitrypsin (AAT) deficiency variants, 10-15 are associated with serum levels below the protective threshold of 11 mmol/L. The diagnosis of severe AAT deficiency is confirmed when the serum level falls below the protective threshold value (ie, 3-7 mmol/L). […] High-resolution CT (HRCT) scanning is more sensitive than standard chest radiography. HRCT scanning is highly specific for diagnosing emphysema and outlines bullae that are not always observed on radiographs. […] These measurements are necessary for the diagnosis of obstructive airway disease and for assessment of its severity. In addition, spirometry is helpful for assessing response to treatment and disease progression. […] The FEV1 is used to stage the severity of COPD. It is normalized as a percentage of predicted for healthy controls. The following Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging system is widely used (note that the postbronchodilator FEV1 is used).

  Spirometry documents the presence of chronic airflow obstruction. Forced vital capacity (FVC) measurement provides data for assessment of expiratory airflow. Measurements of FVC, forced expiratory volume in 1 second (FEV1/FVC), show the presence and degree of airflow obstruction. […] Carbon monoxide diffusing capacity (dlco) testing is performed in conjunction with spirometry to assist in differentiating emphysema from asthma and chronic bronchitis. In emphysema, the dlco is usually decreased because of the loss of surface area of the alveolar-capillary membrane. The combination of a decreased FVC, a decreased FEV1, a decreased dlco, and increased lung volumes and capacities is generally diagnostic of emphysema. […] High-resolution CT may be useful in the diagnosis of subclinical or mild emphysema. High-resolution CT scanners furnish images of low-attenuation lesions associated with emphysema.

  Pulmonary emphysema is defined, in pathological terms, as the permanent enlargement of air spaces distal to the terminal bronchioles and the destruction of the alveolar walls (without fibrosis). […] Emphysema often exists in conjunction with chronic bronchitis in the COPD population; nonetheless, emphysema and chronic bronchitis are two distinct diseases. Although a diagnosis of emphysema can, technically speaking, be made only upon postmortem examination, enough evidence can be accumulated from medical history, physical assessment, and diagnostic procedures to make the correct clinical diagnosis. […] A chest radiograph generally cannot establish the diagnosis of mild emphysema. No remarkable findings appear when mild emphysema exists; however, when emphysema is fully established, classic radiographic findings on an anteroposterior view are typically observed. These findings include bilaterally hyperlucent lungs, flattened hemidiaphragms with widened costophrenic angles, and horizontal ribs.
