Guidelines for an Extubation Trial

Infant	with spontaneous respiratory effort above set ventilator rate
	without evidence of respiratory failure (such as intercostals retractions, poor chest wall movement) and respiratory rate <80 breaths/minute
	with apneic or bradycardic events that decreased in severity and frequency following initiation of methylxanthine therapy
Ventilator rate	≤20 breaths/minute
FiO2 requirement	<40%
Blood gas parameters in the normal range	for arterial blood gas determinations: pH ≥ 7.25 pCO2 <60–64
	for capillary blood gas determinations: pH ≥7.2 pCO2 <70
Saturation (SaO2)	consistently >90%
