Editorial Randomized Controlled Trial Comparative Study
A Randomized Controlled Trial Comparing Two Lung Expansion Therapies After Upper Abdominal Surgery.
Lung expansion therapy is often ordered after surgery to improve alveolar ventilation and reduce risks of postoperative pulmonary complications. The impact of lung expansion therapy at altering ventilation in patients who are not intubated has not been described. The primary purpose of this study was to determine if there is a difference in dorsal redistribution of ventilation and incidences of postoperative pulmonary complications when comparing incentive spirometry (IS) with EzPAP lung expansion therapy after upper abdominal surgery. Our a priori null hypothesis was that there are no differences. ⋯ There was no significant post-lung expansion therapy dorsal ΔEELI% or postoperative pulmonary complications among the adults who received IS or EzPAP 3 times a day after upper abdominal surgery.

Randomized Controlled Trial Comparative Study
Short-Term Effects of an Active Heat-and-Moisture Exchanger During Invasive Ventilation.
Humidification is a standard of care during invasive mechanical ventilation. Two types of devices are used for this purpose: heated humidifiers and heat-and-moisture exchangers (HME). ⋯ This study indicated that, compared with the heated humidifiers, the use of the active HME or the HME increased inspiratory effort, PaCO2 , pH, and dyspnea in stable subjects who were tracheostomized and ventilator-dependent. (ClinicalTrials.gov registration NCT02499796.).

Randomized Controlled Trial
Impact of a Single Session of Inhalation Technique Training on Inhalation Skills and the Course of Asthma and COPD.
A significant percentage of patients with asthma and COPD do not use their inhalers properly. The aim of this study was to evaluate the impact of a single session of inhalation technique training on the frequency of inhalation errors and the course of asthma and COPD. ⋯ Although a single inhalation training leads to a reduction in the number of errors made during inhalation, it does not influence the course of asthma and COPD. The positive effect of a single inhalation technique training is temporary. (ClinicalTrials.gov registration NCT02131454.).
