Pediatric Age-Specific SIRS Criteria

Age	HR (high)	HR (low)	Resp Rate	Min Systolic
Birth – 1wk	>180	<100	>60	60
1wk – 1mo	>180	<100	>50	75
1mo – 2yrs	>180	<90	>35	75
2 – 5yrs	>140	N/A	>30	75
6 – 12yrs	>130	N/A	>20	83
>12yrs	>110	N/A	>20	90

Severe Pediatric Sepsis

Includes SIRS and two or more of the following signs of hypo-perfusion or organ dysfunction that is new and not explained by other known etiology of organ dysfunction:

• Proven need for >50% FiO₂ to maintain saturation ≥ 92%
• Need for non-elective invasive or noninvasive mechanical ventilation
• Glasgow Coma Score ≤11 
• Acute change in mental status with a decrease in Glasgow Coma Score ≥3 points from abnormal baseline

In Hospital Criteria

• Unexplained metabolic acidosis: base deficit > 5.0 mEq/L
• Increased arterial lactate > times upper limit of normal
• Oliguric: urine output <0.5 mL/kg/hr
• Core to peripheral temperature gap > 3°C
• PAO₂/FIO₂ <300 in absence of cyanotic heart disease or preexisting lung disease
• PaCO₂ >65 torr or 20 mmHg over baseline PaCO₂
