*Look for the lowest O2 and highest CO2*
2. ARF: 2 Types: HypOxemic failure from LOW O2 (PaO2 < 60)
HyperCapnic failure from HIGH CO2 (PaCO2 over 50)
3. ARDS/ARF S/S:: ARF: Hypoxemia
-AMS: agitation, restless, confused
-tachy, tachy, sweating
-rapid, shallow breathing pattern
NURS
,ARDS: Refractory Hypoxemia
