6.1 Pneumonia II
Transcript of 6.1 Pneumonia II
Pneumonia IIPathophysiology Course
1. Pleural Effusion Fluid that fills the pleural space (space between the lung itself & the chest wall). This prevents full expansionof the lung, resulting in decreased gas exchange.
2. ARDS (acute respiratory distress syndrome) ARDS, think HARDS - hard stiff lungs
KEY SIGNS1. D - During inhalation = Chest pain 2. D - Dyspnea3. D - Diminished breath sounds4. D - Dull resonance on percussion
88
< 90 SystolicHypotension
Cap refill over 3 - 4 seconds Tachycardia
Early - Fever (Over 100.4)
Elevated WBC (norm: 10,000 or less) Decreased Urine Output
Systolic < 90 mm Hg MAP < 65 mm Hg
30 ml/hr or Less = Kidney Distress
Late - Hypothermia (Under 96.8ᴼF)

Priority Intervention
3. Septic Shock If the infection gets severe, the body releases chemicalsinto the bloodstream to fight the infection resulting in severe low blood pressure & total body inflammation which can damage multiple organs causing them to fail,known as MODS - multiple organ dysfunction syndrome.
S - Shock S - Severely Low BP & perfusion
MEMORY TRICK
- Thoracentesis: big needle in the lung space to drain the fluid! - 2 BIG complications: Pneumothorax (popped lung) Hemothorax (blood in the lung space) - PRIORITY to report: Asymmetrical chest expansion & Decreased breath sounds
