3. VAP- 48-72 hours after endotracheal intubation patient is diagnosed
What are the signs and symptoms of pneumonia?
1. fever / chills
2. SOB / hypoxemia
3. cough / sputum production / purulent sputum
4. leukocytosis or leukopenia
5. pleuritic chest pain
6. tachypnea
7. uremia
8. hypotension
9. confusion
What criteria does the CURB-65 use?
1. confusion
2. uremia ( BUN >20 mg / dL )
3. increased respiratory rate (>30 / min)
4. low blood pressure (< 90 SBP or <60 DBP)
5. age 65 years or greater
What criteria does the Pneumonia Severity Index use?
1. age
2. mental status
3. pulse
4. respiratory rate
5. fever
6. past medical history
7. sex
8. glucose
9. hematocrit

How does the CURB-65 scoring work?
-1 point per each category
0-1 points then treat outpatient
2 points requires short hospital stay
3-5 points requires hospital stay and possibly ICU
What are the physical exam findings for pneumonia?
1. auscultatory findings

-egophony
, -increased tactile remits
-whisper pepctoriloquy
2. tachypnea and tachycardia
3. chest wall retractions and grunting respirations
4. diminished breath sounds over affected area
5. inspiratory crackles during lung expansion
