Study Notes

Respiratory System Overview

The respiratory system provides oxygen to the body's cells while removing carbon dioxide.
The system consists of 3 major parts: the airway, the lungs, and the muscles of respiration.

Upper Respiratory Tract

The upper airway structures consist of the nose, sinuses, nasal passages, pharynx, tonsils and adenoids, larynx, and trachea.

Lower Respiratory Tract

The lower respiratory tract consists of the lungs, which contain bronchial and alveolar structures necessary for gas exchange.

Types of Breathing

Costal (thoracic) breathing involves the external intercostals muscles and is observed by the movement of the chest upward and outward.
Diaphragmatic (abdominal) breathing involves the contraction and relaxation of the diaphragm and is observed by the movement of the abdomen downward.

Physiology of Gas Exchange

Each alveolus is closely associated with a network of capillaries containing deoxygenated blood from the pulmonary artery.
The capillary and alveolar walls are thin, allowing rapid exchange of gases by passive diffusion.
CO2 moves into the alveolus and O2 moves out of the alveolus.

Bronchitis

Definition: Inflammation of the bronchi.
Types: Acute bronchitis and Chronic bronchitis.
Acute bronchitis is a serious lung disease that occurs for more than 2 months or recurs on 2 consecutive years.

Causes of Bronchitis

Lung infections (90% viral, 10% bacterial).
Chronic bronchitis can develop from repeated episodes of acute bronchitis or other repeated lung infections.
Irritants such as smoke, dusts, and air pollution.
Physical agents such as changes in temperature, humidity, and cold drafts.

Predisposing Factors for Chronic Bronchitis

Upper respiratory tract infection.
Pulmonary congestion such as in heart failure.
Bronchial obstruction due to excessive secretions.
Smoking.
Certain occupations (dusty jobs).
Allergy.

Clinical Manifestations of Chronic Bronchitis

Cough that is productive and lasts at least 3 months a year for 2 successive years.
Wheezing.
Dyspnea.
Haemoptysis.
Fever, which may or may not be present.
Lack of energy.
Malaise and headache.

Medical Diagnosis for Chronic Bronchitis

Medical history: ask about cough, breathing problems, and other symptoms.
Physical examination.
Chest x-ray.
Lung or pulmonary function tests (spirometry).
Laboratory tests: complete blood cell count (CBC).
Culture of sputum.
Arterial blood gases (ABG) test.
Alpha 1-antitrypsin (AAT) test.
Electrocardiogram (ECG) to determine if symptoms are caused by or worsened by a heart problem.

Nursing Management for Chronic Bronchitis

Adequate rest and no smoking.
Relieve body aches by taking aspirin.
Drink fluids regularly.
Follow doctor's instructions on ways to help clear mucus.
Note changes in sputum production and cough.
Facilitate removal of bronchial exudates (bronchodilators).
Antibiotics in bronchitis caused by a bacterial infection.
Provide for postural drainage and chest percussion.
Provide proper treatment for acute upper respiratory infections.
Reduce the risk of getting bronchitis by following preventive measures.
