- Pneumococcus / Diplococcus pneumonia
- Streptococcus / staphylococcus – less frequently
Frequent in winter and spring.
3
Q
RISK FACTORS

- COPD, chronic heart failure
- Immunosuppression
4
Q
CLINICAL FEATURES
A
Onset Begins suddenly with rigor and fever ( 39-40) Consolidation Inflammation progress Febrile symptoms and tachypnea continue Resolution Patient improves. No dyspnea Lung begins to function Fever decrease as crisis. Collapse occurs during crisis
5
Q
COMPLAINS
A
Onset • Pleuritic pain- worsen by deep breathing / cough • Dyspnea • Cough • Fever • Severe weakness • Fatigue • Headache Consolidation • Cough w/ sharp pain in affected side • Sputum – rusty red , mucous-purulent
6
Q
PHYSICAL EXAMINATION
A
Onset • State – severe • Cyanotic lips • Tachypnea • Dusky flushed face • Tactile fremitus increased • Herpetic lesions on lips, neck , ears. • Pleural friction rub • Forced position – lie on affected side Consolidation• Still severe • Diffuse cyanosis • Tachypnea ( 35- 40/min) • Tactile fremitus increased • Diminished repiratory excursion. • Pleural friction rub
7
Q
PERCUSSION
A
Onset
• Decreased resonance
Consolidation
• Dull – affected side
8
