1) Patent airway
2) Functional mucociliary escalator
3) Effective cough
4) Normal pulmonary compliance

All four options are important for proper airway clearance, but only options 1, 2, and 3 are necessary. A patent airway prevents obstruction that can impair airway clearance. The functional mucociliary escalator sweeps mucus and other debris out of the airway. An effective cough helps to expel mucus and debris. While normal pulmonary compliance can aid in airway clearance, it is not necessary for normal airway clearance.
