Risk stratification systems are useful for determining hospital discharge policies and antimicrobial therapy in patients with pneumonia, and identifying patients at risk of adverse outcomes.
Many scoring systems exist:
- confusion, urea >7, RR >30 , BP <90/60, age>65
- scoring: 0-1 low risk, 2 mod risk, >3 high risk (30% 30 day mortality)
- confusion, O2 <90%, RR>30, BP<90/60
- scoring: severe pneumonia is 2 or more
|Causes of Respiratory Alkalosis|
|1. Central Causes (direct action via respiratory centre)|
|2. Hypoxaemia (act via peripheral chemoreceptors)|
|3. Pulmonary Causes (act via intrapulmonary receptors)|
|4. Iatrogenic (act directly on ventilation)|
