		50 years old or younger: respiratory rate 25 breaths/minute or more (1 point)
		Over 50 years old: respiratory rate 30 breaths/minute or more (1 point)
Cardiovascular factor
		Tachycardia of 125 beats/minute or more (1 point)
Mental status factor
		Confusion (acute) (1 point)
Oxygenation/Age factors
