As background for the American Association for Respiratory Care (AARC) third 2015 and Beyond conference, we sought information and opinions on the ability of the current respiratory therapy education infrastructure to make changes that would assure competent respiratory therapists in the envisioned healthcare future. ⋯ There are important differences between the baccalaureate-degree and associate-degree programs.

Mycobacterium kansasii disease was diagnosed in an 85-year-old woman admitted to the hospital for cough and gradually worsening breathlessness. Transbronchial biopsy indicated either non-necrotizing granulomata or bronchiolitis obliterans organizing pneumonia (BOOP). She was cured with combined therapy of specific anti-mycobacterial medications and systemic steroids. To our knowledge, this is the first report of M. kansasii non-tuberculous mycobacterium disease with a BOOP-like pattern on lung biopsy.

Intubation and mechanical ventilation can impair mucociliary clearance and cause secretion retention, airway occlusion, atelectasis, and pneumonia. Animal and laboratory work has demonstrated that mechanical ventilator settings can generate a flow bias (inspiratory or expiratory) that may result in mucus movement either away from the ventilator (deeper into the lungs) or toward the ventilator (toward the mouth), respectively. An absolute difference of 17 L/min, and a relative difference of ≥ 10%, between the expiratory and inspiratory flow have been reported as thresholds for mucus movement. ⋯ Commonly used mechanical ventilator settings generate an inspiratory flow bias that may promote secretion retention.
