Priority 2		Patients requiring intensive monitoring and may potentially need immediate intervention.
Priority 3		Unstable critically ill patients but have a reduced likelihood of recovery because of underlying disease or nature of their acute illness.
Priority 4	A	Little or no anticipated benefit from ICU care based on low risk of active intervention that could not safely be administered in a non-ICU setting (too well to benefit from ICU care).
	B	Patients with terminal and irreversible illness facing imminent death (too sick to benefit from ICU care).
