A physical examination may show wheezing, decreased breath sounds, or prolonged exhalation (exhalation takes more than twice as long as inspiration. The chest may be barrel-shaped. There may be signs of chronically insufficient oxygen levels in th...

A diagnosis of emphysema will not be made on the basis of the above symptoms alone. A detailed medical history will be taken along with x rays and pathology examinations. Peak flow tests will also be conducted.
|
 |
In addition, patients with advanced emphysema may show a smaller or vertical heart. Abnormal findings on the chest x ray include over-inflation of the lungs and an abnormally increased chest diameter.
|
 |
Other tests that may be performed include peak flow measurements, arterial.

Blood gases measure the pH (acidity), oxygen content, and carbon dioxide content of the blood. Usually, blood gases are used to analyze the arterial blood. In rarer cases, venous blood may be used.
|
 |
Blood gas analysis, also called arterial blood gas (ABG) analysis, is a procedure to measure the partial pressure of oxygen (O 2 ) and carbon dioxide (CO 2 ) gases and the pH (hydrogen ion concentration) in arterial blood. Purpose Blood gas analysis is used to diagnose and evaluate respiratory diseases and conditions that influence how effectively the lungs deliver oxygen to and eliminate carbon dioxide from the blood.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a test which measures the amounts of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood. Purpose An ABG analysis evaluates how effectively the lungs are delivering oxygen to the blood and how efficiently they are eliminating carbon dioxide from it.
|
 |
Blood gases are defined as the mixture of gases, including oxygen (O 2 ), carbon dioxide (CO 2 ), and nitrogen (N 2 ), dissolved in the fluid fraction of blood. Oxygen from the air is transported from the lungs to all tissues of the body, where it is needed for metabolism ; and carbon dioxide, a by-product of metabolism, is taken from the tissues to the lungs to be eliminated.

A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.
|
 |
A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest area.

A tomogram refers to a slice, or section, which is imaged by moving the X-ray tube and recording film simultaneously and in opposite directions. This method serves to blur out structures in front of and behind the area of interest.

Computed Tomography (CT)Computed tomography(CT) is a test that combines x-rays and computer scans. The result is a detailed picture that can show problems with soft tissues (such as the lining of your sinuses), organs (such as your kidneys or lung...

Computed tomography (CT) of the chest is performed to diagnose a variety of symptoms, including vascular, cardiac, airway disease as well as cancers that can occur in the thoracic region of the body. Purpose The purpose of the CT scan is to noninvasively and quickly visualize internal organs which may be damaged by disease or trauma.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body) Palpation (feeling the body with hands) Auscultation (listening to sounds) Percussion (producing sounds)
|
|
A physical examination is an evaluation of the body and its functions using inspection, palpation (feeling with the hands), percussion (tapping with the fingers), and auscultation (listening). A complete health assessment also includes gathering information about a person ' s medical history and lifestyle, doing laboratory tests, and screening for disease.
|
 |
The health history is a current collection of organized information unique to the individual patient. Relevant aspects of the history include biographical, demographic, physical, mental, emotional, sociocultural, sexual, and spiritual data.

Lung plethysmography is a test used to measure how much air you can hold in your lungs. See also: Limb plethysmography; Plethysmography.

Pulmonary function tests are a broad range of tests that are usually done in a health care provider's office or a specialized facility. They measure how well the lungs take in and exhale air and how efficiently they transfer oxygen into the blood. Spirometry measures how well the lungs exhale. The information gathered during this test is useful in diagnosing certain types of lung disorders, but is most useful when assessing for obstructive lung diseases (especially asthma and chronic obstructive pulmonary disease, COPD). Lung volume measurement detects restrictive lung diseases. In this set of diseases, a person cannot inhale a normal volume of air. Restrictive lung diseases may be caused by inflammation or scarring of the lung tissue (interstitial lung disease) or by abnormalities of the muscles or skeleton of the chest wall. Testing the diffusion capacity (also called the DLCO) permits an estimate of how efficiently the lungs transfer oxygen from the air into the bloodstream.

Pulmonary function tests are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthma , bronchitis or emphysema .

Pulmonary function tests are a group of procedures that measure how well the lungs are functioning. Purpose Pulmonary function tests help a doctor to diagnose respiratory diseases and disorders such as asthma , chronic obstructive pulmonary disease (COPD), and emphysema, and mechanical injury by measuring the degree of lung impairment.

A pulmonary function test shows how well your lungs are working. A complete test has three parts. You may be given the entire test or only certain parts. The entire test is painless and lasts 45–90 minutes.
|
|
Normal individuals have a large reserve in lung function that allows breathing capacity to increase at least twenty to thirty times during periods of vigorous physical activity. It is not the ability to breathe that normally limits maximum exercise capability, nor does physical activity normally change lung function, either in the short-term or over time with training.
|
 |
A pulmonary ventilation/perfusion scan is a pair of nuclear scan tests that use inhaled and injected radioactive material (radioisotopes) to measure breathing (ventilation) and circulation (perfusion) in all areas of the lungs.
|
|
A lung perfusion scan is a nuclear medicine test that produces a picture of blood flow to the lungs. A lung ventilation scan measures the ability of the lungs to take in air and uses radiopharmaceuticals to produce a picture of how air is distributed in the lungs.
|
|
A lung perfusion scan and ventilation study are two diagnostic imaging studies. A lung perfusion scan assesses blood flow to the lungs .
