Which method is NOT typically used for clearing respiratory secretions?

Incentive spirometry is designed primarily for encouraging deep breathing and lung expansion rather than clearing respiratory secretions. It is commonly used to prevent atelectasis, improve lung function, and enhance overall ventilation but does not actively remove mucus or secretions from the airways.

Huffing or forced expiration techniques, vibrations, and suctioning are all methods directly associated with clearing secretions. Huffing techniques help mobilize secretions by creating a forceful expulsion of air, vibrations assist in loosening mucus from airway walls, and suctioning is a procedure employed to physically remove secretions from the airways.

Thus, understanding the distinct purposes of these methods emphasizes why incentive spirometry stands out as the option not typically employed for the direct removal of respiratory secretions.
