Document Summary
Describe the respiratory pathophysiology of pneumonia using the clinical reasoning model: definition, an acute inflammatory condition of the lung parenchyma. Infective disorder: pathology, alveolar spaces are filled partially or completely with fluid and blood cells (infectious debris & exudate, aetiology, bacteria, fungal or viral. Infection only occurs when organisms overcome the normally effective lung defence mechanisms - as a result of either lungs" defences being defective or overwhelmed by the virulence or quantity of organisms: classification, site of infection. Immunocompromised individuals: chronic respiratory disease, alcoholism, altered level of consciousness, smoking, malnutrition. Irritant to airways -> increase mucus -> damages cilia: can change pattern of breathing -> shallow breaths -> cough not affective. List the respiratory signs and symptoms of a patient presenting with pneumonia: constitutional symptoms (acute infection, cough, changed pattern of breathing, sputum/haemoptysis, chest wall pain, auscultation wheeze, crackles, decreased/bronchial breath sounds, cxr infiltrate/opacity, abg.
