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...

Emphysema is a progressive, incurable chronic lung condition. The air sacs (alveoli) are destroyed and oxygen uptake is restricted due to the loss of elasticity of lung tissue.
|
 |
Emphysema is a chronic respiratory disease where there is over-inflation of the air sacs (alveoli) in the lungs, causing a decrease in lung function, and often, breathlessness.

 |
Emphysema is a chronic respiratory disease in which overinflation of the alveoli or air sacs causes a decrease in respiratory function and often dyspnea.

Blood gases is a test done to measure how much oxygen and carbon dioxide is in your blood. It also looks at the acidity (pH) of the blood. Usually, blood gases look at blood from an artery. In rarer cases, blood from a vein 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 chest tomogram is a picture of the chest area created by moving the x-ray machine in one direction while moving the recording film the other way. This method blurs structures in front of and behind the area of the chest being studied.

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.

Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move oxygen into the blood.
|
 |
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 .
|
|
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.

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

Pulmonary Exercise Stress TestRisks and ComplicationsLike many tests, this test involves some risks. They may include:Shortness of breath or wheezingRise or fall in blood pressureFainting, dizziness, or fatigueAbnormal heartbeat or heart rateHeart...
|
|
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.

The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of the blood . A pulse oximeter uses infrared light and a photo sensor to detect the amount of oxygen in a patient's blood.
|
|
The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of blood. Purpose A pulse oximeter measures the amount of oxygen present in blood by registering pulsations within an arteriolar bed (an area between arteries and capillaries).

Detailed information on peak flow meters, including how to obtain one, how to measure personal best peak flow, peak flow zones, and how a peak flow meter should be used, and information on oximeters and spirometer
|
|
|
The peak expiratory flow rate measures how fast a person can breathe out (exhale) air. It is one of many tests that measure how well your airways work.
|
|
Spirometry is the measurement of airflow into and out of the lungs . The patient is given instructions on how to perform the breathing maneuvers.
|
|
Spirometry is the measurement of air flow into and out of the lungs. Spirometry requires that the nose is pinched off as the patient breathes through a mouthpiece attached to the spirometer.
|
 |
A pulmonary ventilation/perfusion scan is a pair of nuclear scan tests. These tests 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 .
