Endotracheal suctioning is mandatory to prevent complications caused by the retention of tracheal secretions. Endotracheal suctioning is often performed late, when patients show signs of respiratory and hemodynamic alterations. We conceived a prototype device that, when synchronized with the ventilator, automatically removes secretions collected below the endotracheal tube (ETT) cuff, thus avoiding endotracheal suctioning. The aim of our investigation was to assess the performance of this novel prototype in vitro. ⋯ We conceived an system capable of automatically expelling fluid from below the ETT cuff outside an experimental trachea by generating an artificial cough maneuver. This system may decrease the use of endotracheal suctioning and its complications. Future in vivo studies are needed to confirm this first in vitro evaluation.

Single-step tests have been proposed as simple and inexpensive challenges to diagnose exercise-induced bronchoconstriction (EIB) in the pediatric population. Work performed and the resulting ventilation, however, might be substantially lower in stepping than running. This might decrease the diagnostic yield of step-based challenges. ⋯ Lower prevalence of EIB in stepping compared to treadmill running is not related to less ventilation demand in the former modality. Although stepping might be useful as a screening EIB test due its portability and low cost, a negative test should be confirmed with a running-based test in symptomatic children.

The modified early warning score (MEWS) is used to detect early clinical deterioration and to escalate care as needed. Respiratory therapists (RTs) usually do not use the MEWS even when it is implemented as a default in the electronic health record system. This study explored whether the technology acceptance model could predict the intentions of RTs to use the MEWS. ⋯ Numerous studies have demonstrated that a change in behavioral intention is a good predictor of change in behavior. The increase in the RTs' knowledge, attitude, and behavioral intention scores after MEWS education indicated that these RTs may be more inclined to use the MEWS if they were educated about its clinical relevance and if their attitude toward using it were favorable. Analysis of the study results also indicated that the technology acceptance model could serve as a framework to guide respiratory care managers in the development of strategies to successfully implement new systems or processes that are intended to be used by RTs.
