Shen et al identified factors predictive of the duration of mechanical ventilation in a patient with carbon monoxide poisoning. The authors are from National Defense Medical Center in Taipei.
Patient selection: acute respiratory failure associated with severe carbon monoxide poisoning
Initial management: endotracheal intubation and mechanical ventilation
Parameters for of early extubation (less than 72 hours):
(1) toxicologic drug screen
(2) serum troponin I level on admission to ED

= SUM(points for the 2 parameters)
Interpretation:
• minimum score: 0
• maximum score: 2
• A patient with a score of 2 was more likely to have an early extubation.
