Transcript of Obstructive Pulmonary Disorders

Lower Repiratory Tract Issues Obstructive Pulmonary Disorder air doesn't flow freely in the airways
the time it takes to inhale or exhale is greatly increased Chronic Obstructive pulmonary disorders (copd) chronic obstruction of the flow of air through the airways and out of lungs
generally permanent
may be progressive overtime What causes COpD? cigarette smoking and second-hand smoke
air pollution
occupational pollutants
alpha-1 antitrypsin deficiency (AAT) Chronic Bronchitis inflammation and swelling of the lining of the airways that leads to narrowing and obstruction of the airways
produces mucous (sputum) which also obstruct airways
increases possibility of bacterial lung infections
symptoms: daily cough with production of mucous for 3 months chronic asthma inflammation of the airways as well as spasm of muscles surrounding the airways in asthma--the results from spasm in the muscles is called bronchospasm
inflammation of the airways also cause the thickening of the walls Bronchiectasis serious and repeated infections of the lung as well as abnormal development of the lungs results in permanent damage to the airways
airways become enlarged tubes or large sacs
the damaged, mucus-filled airways become infected--this causes further inflammation and damage to the airways
people with this often have vigorous cough producing large amounts of infected mucus
Emphysema permanent enlargement of the alveoli
Often preceded by chronic bronchitis
the destruction of the alveolar walls reduces the elastic tissue of the lung—leads to collapse of the bronchioles obstructing airflow out
air is trapped in the alveoli and reduces the ability of the lung to shrink when you try to exhale
This prevents the exchange of gasses and prevents oxygen from getting to the brain and heart causing depression, sluggishness and irritable
Exercise, drug therapy, supplemental oxygen and surgery may relieve symptoms and possibly slow progression emphysema
Restrictive Pulmonary Disorders vital capacity is reduced because the lungs have lost their elasticity Lower respiratory infections bronchitis
tuberculosis . Pulmonary fibrosis is a condition in which fibrousous tissue builds up in the lungs. Acute Bronchitis an infection of the primary and secondary bronchi
Usually it is caused by a viral URI that has led to a secondary bacterial infection
commonly results in a deep cough that coughs up mucus and sometimes pus
Pneumonia viral or bacterial infection in which the bronchi and alveoli sacs (the alveoli sacs are the air sacs in the bronchi)fills with a thick fluid
most common in elderly people and to them can also be fatal
You have a better chance of getting pneumonia from a weakened immune system, smoking, and being immobilized
symptoms on Pneumonia are high fever, productive cough, difficulty in breathing, headache, and chest pain
can be localized in specific lobules of the lungs
Aids patients are subjected to a rare form of pneumonia due to there weakened immune system
Pulmonary Tuberculosis by the tubercle bacillus, which is a type of bacterium
When the tubercle bacilli invade the lung tissue, the cells build a protective capsule around them to keep them from spreading to the rest of the body
capsule in which they are enclosed is called a tubercle
