It is unknown whether lung mechanics differ between patients with pediatric ARDS and at risk for ARDS. We aimed to examine the hypothesis that, compared to ARDS, subjects at risk of ARDS are characterized by higher end-expiratory lung volume (EELV) or respiratory system compliance (CRS) and lower distending pressure (stress) applied on the lung or parenchymal deformation (strain) during mechanical ventilation. ⋯ Longitudinally, CRS and EELV were lower and strain and stress were higher in subjects with ARDS compared to subjects at risk for ARDS. These parameters behaved differently over time at PEEP values of 4 or 10 cm H2O. At these PEEP levels, strain and stress remained within safe limits in both groups.

Music therapy, as a non-drug therapy, is widely used in patients with COPD. However, the effects of music therapy on dyspnea, anxiety, depression and other physiological parameters has not been elucidated. Therefore, we sought to investigate the effects of passive music therapy (listening to music) and mixed music (combination of listening and singing) in adults with COPD. ⋯ Music therapy is effective in reducing dyspnea and anxiety in subjects with COPD. Additionally, music therapy may also improve sleep quality and physiological parameters of subjects with COPD. However, our conclusions need to be supported further by larger and longer well-designed trials.

Electronic Medical Record-Based Pager Notification Reduces Excess Oxygen Exposure in Mechanically Ventilated Subjects.
Liberal oxygenation during mechanical ventilation is harmful in critically ill patients and in certain subsets of patients, including those with stroke, acute myocardial infarction, and cardiac arrest. Surveillance through electronic medical records improves safety of mechanical ventilation in the ICU. To date, this practice has not been used for oxygen titration ([Formula: see text]) in adults. We hypothesize that a surveillance system based on the electronic medical record to alert respiratory therapists to titrate [Formula: see text] is feasible, safe, and efficacious. ⋯ Use of an electronic surveillance system to titrate [Formula: see text] was safe and feasible and showed preliminary efficacy in reducing hyperoxemia. Our study serves to justify larger randomized controlled trials for [Formula: see text] titration.
