Complication: Shock and respiratory failure Different types of pneumonia CAP-Community acquired pneumonia- 48 hrs after hospitalization. HCAP- Health care associated pneumonia- nursing home HAP-hospital acquired pneumonia- 48 hrs after admission. VAP- ventilator acquired pneumonia- 48 hours after intubated Plueral Effusion fluid build up in plueral space; secondary to other infections. Complications of HF, TB, Pneumonia. s/s: Absent breath sounds decreased fremitus Aspiration inhalation of foreign material into lungs. Can cause pneumonia, and result in tachycardia, dyspnea, htn, hypotension. Sever Acute Respiratory Syndrome (SARS) viral illness; TB infectious disease; can spread to kidneys, bones and lymph nodes. s/s: Low grade fever Cough Night sweats weight loss BCG vaccine PPD (Mantoux) determines if you have come into contact with Lung Abscess Necrosis of pulmonary parenchyma. S/S: Odor sputum Fever Cough Dyspnea Weakness Anorexia Weight loss Pleurisy Inflammation of both layers of the pleurae. Develops with other infections. Coughing/sneezing worsens pain.
