1) Periodic oropharyngeal suctioning can help prevent the accumulation of secretions in the oropharynx, reducing the risk of aspiration.
2) Spontaneously breathing patients are less likely to aspirate compared to mechanically ventilated patients because the cough reflex is intact and the airway clearance mechanisms are more functional. 
3) Methylene blue test involves injecting methylene blue dye through the tracheal tube cuff to detect any leaks into the subglottic space, which can increase the risk of aspiration. 
4) Tracheostomy tubes have a higher risk of aspiration compared to endotracheal tubes because of the longer length, increased dead space, and deviation from the natural tracheal anatomy, which can impair airway clearance mechanisms.
