Continuous high-frequency oscillation (CHFO) is a therapeutic mode for the mobilization of secretions. The Metaneb CHFO device also incorporates aerosol administration using an integrated jet nebulizer. However, the effectiveness of aerosol delivery and influential factors remain largely unreported. ⋯ Inhaled dose with a jet nebulizer via the Metaneb CHFO device was lower than with a jet nebulizer alone. Placement of a vibrating mesh nebulizer at the airway and distressed breathing increased inhaled dose.

Clinical preceptors in respiratory therapy (RT) are expected to possess effective teaching skills and qualities that signify their knowledge, expertise, and professionalism. Thus, it is important to determine which teaching characteristics are effective among RT clinical preceptors from the administrators' perspective as well as the predictors for the administrators' decisions. ⋯ This study indicates that the professional competence of clinical preceptors is believed by RT administrators to be the most important behavioral characteristic. The results also indicate that role modeling and showing genuine interest in patients and their care are the most effective teaching characteristics of clinical preceptors.

Diffuse cystic lung diseases (DCLDs) are a group of diverse pulmonary disorders with varying pathophysiology that are characterized by the presence of thin-walled, air-filled spaces within lung parenchyma. High-resolution computed tomography plays a crucial role in the evaluation of DCLDs, and cyst characteristics such as morphology, distribution, and the presence of other associated radiologic findings can help distinguish between different DCLDs. DCLDs can be classified according to their underlying pathophysiology as neoplastic, genetic, lymphoproliferative, infectious, associated with other forms of interstitial lung disease, or related to smoking. In this review we will provide a clinical overview on the most common DCLDs that are encountered in clinical practice: lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis, Birt-Hogg-Dubé syndrome, and lymphoid interstitial pneumonia/follicular bronchiolitis, with a focus on practical aspects that can help clinicians in the optimal diagnosis and management of patients with DCLDs.
