Randomized Controlled Trial Comparative Study
Comparison between automatic tube compensation and continuous positive airway pressure during spontaneous breathing trials.
Various methods to perform spontaneous breathing trials (SBTs) exist, but no one method has been shown to be superior. Automatic tube compensation (ATC) is a new and potentially advantageous ventilation mode to use during SBT. We compared ATC to continuous positive airway pressure (CPAP) during SBTs, to determine their efficacy in identifying patients ready to be liberated from mechanical ventilation. ⋯ When applied as part of a respiratory-therapist-driven weaning protocol in a general intensive-care population, SBTs with ATC were safe but did not hasten liberation from mechanical ventilation, when compared to CPAP.

Diagnostic or therapeutic flexible bronchoscopy is often necessary in severely ill patients. These patients often have comorbidities that increase the risk of bronchoscopy-related complications. ⋯ Noninvasive ventilation may prevent hypoventilation in patients with obstructive sleep apnea and obesity hypoventilation syndrome who require bronchoscopy, and may assist in the bronchoscopic evaluation of patients with expiratory central-airway collapse. We describe the indications, contraindications, and technique of flexible bronchoscopy during noninvasive ventilation.

Comparative Study
Effects of imposed resistance on tidal volume with 5 neonatal nasal continuous positive airway pressure systems.
Neonates with respiratory distress syndrome are often treated with nasal continuous positive airway pressure (CPAP). Nasal CPAP methods include electronic feedback control, underwater seal, flow opposition, and flow opposition with fluidic flow reversal on expiration. Few studies have compared those modes, and the results have been contradictory. ⋯ The differences in these nasal CPAP systems correlate with the differences in unassisted V(T) due to loading effects. The ventilator imposed the least load, and the AirLife nasal CPAP system imposed the most.

Comparative Study
Prevalence of chronic obstructive pulmonary disease and tobacco use in veterans at Boise Veterans Affairs Medical Center.
Although its prevalence is still debated, chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in the United States, and smoking cessation remains the only intervention that can significantly improve the prognosis of COPD. ⋯ The prevalence of COPD in patients at the Boise Veterans Affairs Medical Center was consistent with that in other United States surveys, although the underutilization of screening spirometry in those at risk for COPD may have caused underestimation of the prevalence. Smoking, age, and male sex were identified as significant risk factors for COPD, and the prevalence of active smoking remains high in this population of veterans.

The American Association for Respiratory Care has established a task force to identify potential new roles and responsibilities of respiratory therapists (RTs) in 2015 and beyond. The first task force conference confirmed that the healthcare system in the United States is on the verge of dramatic change, driven by the need to decrease costs and improve quality. Use of evidence-based protocols that follow a nationally accepted standard of practice, and application of biomedical innovation continue to be important competency areas for RTs. ⋯ The education needed by the workforce to assume the new responsibilities emerging as the healthcare system changes starts with a close look at the competencies that will be needed by graduate RTs upon entry into practice. Future specialty practice areas for experienced RTs are identified without defining specific competencies. We present the findings of the task force on the competencies needed by graduate RTs upon entry into practice in 2015.
