Protocol for incentive spirometry?

IS is part of our post-op order sets. Implementing IS have always been a nursing responsibility as part of bedside patient education but requires a provider order. In our post-extubation patients, we've devised a protocol that allows the RT to decide on which lung expansion or airway clearance modality would work for specific patients since IS isn't the only device out there. We write an order for RT to assess and determine whether IS, EZ-Pap, Acapella Valve, Aerobika OPEP is more appropriate. The same order can apply to medical patients who are not post-extubation but can benefit from lung expansion or airway clearance strategies that requires an expertise of an RT to determine.
