Inclusion Criteria for Critical Care Admission

Variable	Inclusion Criteria for Critical Care Admission
Requirement for invasive ventilatory support	Refractory hypoxemia (Spo2 < 90% on nonrebreather mask Fio2 > 0.85) Respiratory acidosis with pH < 7.2 Clinical evidence of respiratory failure Inability to protect or maintain airway
Hypotension	SBP < 90 mm Hg for adults (see BP parameters for all age-groups in Table 3) or relative hypotension with clinical evidence of shock for all ages (altered level of consciousness, decreased urine output, other end-organ failure) refractory to volume resuscitation requiring vasopressor/inotrope support that cannot be managed on the ward

SBP = systolic BP; Spo₂ = oxygen saturation as measured by pulse oximetry.
