A Confused Patient with a Tracheostomy Tube Is Breathing Shallowly

A confused patient with a tracheostomy tube is breathing shallowly at 8 times per minute. He is nonverbal because of the tracheostomy and has an SpO₂ at 81% on room air. Your immediate action would be to:

A) attach a bag-valve device to the trachea and start ventilation.
B) place a trach mask over the tube and administer high-concentration oxygen.
C) deflate the cuff on the trach tube and begin positive pressure ventilation.
D) use the bag-valve device with a pediatric mask and ventilate by sealing it over the tube.
