Chap 4 - Respiratory Diseases part 1 Flashcards
Sudden onset of hyperreactivity of the bronchi and bronchioles with bronchospasm. Inflammation and swelling severely narrow the lumens. Attacks triggered by dust, mold, cigarette smoke, inhaled chemicals, exercise, cold air, or emotional stress. Or cockroaches in cities.
Asthma
Asthma that’s prolonged, extremely severe and life-threatening attack.
Status asthmaticus
Acute or chronic inflammation or infection of the bronchi. Inflammation due to pollution or smoking causes a constant cough, mucus production, and wheezing.
Bronchitis
Chronic, permanent enlargement and loss of elasticity of the bronchi and bronchioles. Chronic inflammation destroys the smooth muscle in the walls, and the bronchi become markedly dilated. Symptoms are lots of mucus and coughing. Common with cystic fibrosis.
Bronchiectasis
Creaking, grating, or rubbing sound when the two layers of the inflamed pleura rub against each other during respiration.
Pleural friction rub
Irregular cracking or bubbling sounds during inspiration. Wet ones are caused by obstruction of the alveoli by fluid or infection. Dry ones are caused by chronic irritation or fibrosis.
Rales
Humming, whistling, or snoring sounds during inspiration or expiration. They are caused by swelling, mucus, or a foreign body that partially obstructs the bronchi.
Rhonchi
A high-pitched, harsh, crowing sound due to obstruction in the trachea or larynx.
Stridor
High-pitched whistling or squeezing sounds during inspiration or expiration. They can often be heard without a stethoscope. They are caused by extreme narrowing of the bronchi due to bronchospasm.
Wheezes
Precipitated by a severe infection or burns that affect the entire body’s can also be caused by indirect injury to the lungs (inhale vomit or fumes). The alveoli are damaged because of lack of blood flow, are unable to make surfactant, and they collapse with each breath.
Acute Respiratory Distress Syndrome (ARDS)
Incomplete expansion or collapse of part or all of a lung due to mucus, tumor, trauma, or a foreign body that blocks the bronchus. Also known as collapsed lung.
Atelectasis (atelectatic lung)
Combination of chronic bronchitis and emphysema caused by chronic exposure to pollution or smoking. In emphysema, the alveoli rupture, creating large air spaces in the lungs. Air can be inhaled but not exhaled. Due to chronic over expansion of the lungs, the thorax becomes deformed (barrel chest).
Chronic Obstructive Pulmonary Disease (COPD)
Inherited, eventually fatal disease caused by a recessive gene. Cystic fibrosis affects all the exocrine cells (those that secrete mucus, digestive enzymes, and sweat), but the respiratory system is particularly affected. Mucus is extra think and blocks alveoli and bronchioles. The pancreas develops cysts that become fibrous tissue.
Cystic Fibrosis (CF)
Acute viral infection of the upper and lower respiratory tracts. Symptoms include fever, severe muscle aches, and cough.
Influenza (Flu)
Caused when aspirin is used to relieve flu symptoms in children. It causes very high levels of ammonia in the blood and brain, vomiting, seizures, and liver failure. Can be acute or fatal.
Reye’s Syndrome
