  • Is the airway patent?
  • Is there evidence of respiratory distress?
  • Hemodynamic status, hypotension, tachycardia, evidence of shock?

• Does the patient have any electrolyte abnormalities that require immediate attention?
  • K < 2.5 or > 6; Na < 120 or > 150; ECG abnormalities
  • Severe metabolic acidosis (pH < 7.2)
  • Assess volume status: hypervolemic, euvolemic or hypovolemic
