PNEUMONIA Flashcards
Types of microbes that can cause pneumonia
Bacteria
Virus
Fungi
CURB-65 score parameters
Confusion
Uremia >7mmol/l
Respiratory rate > 30 in adults and >50 in children
Blood pressure, systolic<90 or diastolic<60
Age <5yrs or >65yrs
Different approaches managing pneumonia patient based on their CURB65 scores
0-1 outpatient management
2-3 short inpatient hospitalisation
>3 admit and consider intensive care
Additional factors that warrant hospitalisation in pneumonia patients
Comorbidities such as chronic lung disease, heart failure or renal disease
Extensive disease, multiple lobes involved
Low oxygen saturation SpO2, < 92% on room air
Severe tachycardia
