Study Notes
Respiratory Disorders
- Respiratory structures such as the airways, alveoli, and pleural membranes can be affected by various disease processes.
- Infections, obstructive disorders, restrictive disorders, and cancers can alter pulmonary function.
Infections
- Respiratory infections can occur in the upper or lower respiratory tract, or both.
- Organisms capable of infecting respiratory structures include bacteria, viruses, and fungi.
- Infections can range from mild to severe and even life-threatening.
Upper Respiratory Tract Infections
- The common cold is caused by viral pathogens such as rhinovirus, parainfluenza virus, respiratory syncytial virus, adenovirus, and coronavirus.
- These viruses tend to have seasonal variations in their peak incidence.
- Manifestations of the common cold include rhinitis, sinusitis, pharyngitis, headache, and nasal discharge and congestion.
Influenza
- Influenza is a viral infection that can affect the upper or lower respiratory tract.
- Three distinct forms of influenza virus have been identified: A, B, and C, with type A being the most common and causing the most serious illness.
- Influenza virus is highly transmissible and has a high tendency for genetic mutation, resulting in new variants arising around the world.
Lower Respiratory Tract Infections
- Pneumonia is a condition that involves inflammation of lower lung structures such as the alveoli or interstitial spaces.
- Pneumonia can be caused by bacteria or viruses such as pneumocystis carinii.
- Individuals most at risk for pneumonia include the elderly, those with viral infections, chronically ill, AIDS or immunosuppressed patients, smokers, and patients with chronic respiratory disease.
Treatment of Pneumonia
- Antibiotics are used if the infection is bacterial in origin.
- Oxygen therapy is used to treat hypoxemia.
- A vaccine for pneumococcal pneumonia is available and highly effective.
Respiratory Tract Drugs
- Drugs are used to treat acute and minor conditions, as well as chronic and serious conditions.
- Examples of respiratory tract drugs include those used to treat bronchial asthma, chronic bronchitis, cystic fibrosis, and emphysema.
Drugs Used to Treat Respiratory Tract Irritation and Control Secretion
- These drugs are used to treat symptoms of cough and irritation that result from common cold, seasonal allergies, and upper respiratory tract infections.
- Examples include antitussives, decongestants, antihistamines, and leukotriene inhibitors.
Chronic Obstructive Pulmonary Disease (COPD)
- COPD is a persistent obstruction of the airways.
- Chronic bronchitis is a long-standing inflammation of the bronchial tree, characterized by production of sputum on most days for 3 months of 2 successive years.
- Emphysema is a pathological condition in which there is dilatation of the air spaces by destruction of the alveolar walls, resulting in obstruction from the decrease of the lungs' elasticity.
