Sputum induction is a straightforward and non-invasive procedure designed for patients who struggle to produce sputum naturally. The patient inhales a nebulized hypertonic saline solution(i.e hyperconcentrated normal saline), which helps to liquefy the secretions in the airways.
This process facilitates coughing, making it easier to expel respiratory secretions. If successful, sputum induction often eliminates the need for a more invasive procedure like bronchoscopy.
