a. position the infant head down and rub its back to stimulate breathing. b. begin immediate ventilation with oxygen using the bag-valve mask. c. intubate the trachea and apply suction to the ET tube to remove any foreign material from the lower airway. d. give blow-by oxygen and transport immediately.
