Diseases of the Respiratory System


Structure and Function








Air enters Nasal Cavity, pharynx
Larynx to trachea
Bronchi – each lung then bronchioles,
alveoli
Exchange of oxygen for carbon dioxide,
expel carbondioxide, oxygen flows into
blood system.
Diaphragm and muscles between ribs help
air to enter and exit lungs.

Diagnostic Procedures








Sprirometer – tests vital capacity volume,
draw in as much air as possible then expel
as much as possible.
FEV – forced-expiratory volume. Maximum
air expelled in one second of time.
Oscillometry – Breathe normally for 20-30
seconds, then it shoots sound waves into

the air passages and measures echo.
Arterial blood gases – evaluate levels of
oxygen and carbon dioxide and blood pH

Lower Respiratory Disease
Signs and symptoms

COPD – includes bronchitis, asthma,
emphysema, cystic fibrosis, and pneumonia
 Bronchitis – chest pains, dyspnea, cough,
fever, chills, hypoxia
 Asthma – breathlessness or panting, wheezing,
 Emphysema – suffocating feeling, distressed
breathing, collapsed lung
 Cystic Fibrosis – inherited, dyspnea, wheezing,
persistent cough, thick sputum
 Pneumonia – dyspnea, fever, chest pain,
productive cough

Lower Respiratory Disease
Signs and symptoms







Pleurisy – Painful breathing – complication of
pneumonia
Legionnaire’s disease – fatigue, coughing,
sob, neuromuscular impairments, collapsed
lung
Primary atypical pneumonia (walking) – flu-like
symptoms, fatigue, fever, weakness, headache,
sore throat, GI disorders – can become worse,
but generally can function among others with
this disease
Primary TB – Cough with sputum, difficult to
diagnose without know contact
