 Increased oxygen at low levels can also be delivered using a nasal cannula, which additionally may provide some stimulation due to the tactile stimulation of the cannula.CPAP (continuous positive airway pressure) is sometimes used for apnea when medications and supplemental oxygen are not sufficient.Usually as a last resort, mechanical ventilation is used to support infants whose apnea cannot be controlled sufficiently by other methods and where the potential risk of harm from recurrent hypoxia is felt to outweigh the risks of injury from ventilation.
