The aim of this study was to define the level of peak inspiratory pressure (PIP) and mean airway pressure ([Formula: see text]) at which a pneumothorax is produced in an in vivo ARDS neonate model. In addition, we analyzed the hemodynamic response and cerebral parameters during the progressive increase of intrathoracic pressure. ⋯ A progressive increase of PEEP at a constant driving pressure did not increase severe adverse events at the range of pressures that we routinely use in neonates with ARDS. Asystole, pneumothorax, and cerebral compromise appeared at high intrathoracic ranges of pressure. Hemodynamics must be strictly monitored in all patients during the performance of lung recruitment maneuvers because hemodynamic deflections emerge early, at a range of pressures commonly used in ventilated neonates with ARDS.

Effectiveness of mechanical assisted coughing with insufflation-exsufflation (MI-E) in amyotrophic lateral sclerosis (ALS) depends largely on severity of bulbar dysfunction, which can generate different upper-airway responses. The aim of the study was to evaluate the use of graphs generated by MI-E in ALS to detect airway obstruction and set parameters to achieve an effective mechanically assisted coughing. ⋯ Analysis of graphics generated by applying MI-E in ALS was an effective method to detect upper-airway responses and select optimal set parameters. Obstruction during insufflation is related to bulbar upper motor neuron dysfunction and collapse during exsufflation to bulbar lower motor neuron dysfunction.

The purpose of this study was to ascertain whether the COVID-19 pandemic and the instructional changes implemented in response to it affected student enrollment, retention, or success on the National Board for Respiratory Care credentialing examinations at an associate degree respiratory care program in the state of Texas. ⋯ The COVID-19 pandemic and the instructional changes implemented in response to it decreased students' first-time pass rate on the Therapist Multiple-Choice examination in the mid-pandemic group compared with the pre- and early-pandemic groups.

Unplanned extubation (UE) is associated with adverse outcomes. The aim of the study was to compare the clinical outcomes in preterm infants who experienced at least one UE to those who did not experience any UE. ⋯ Infants who experienced UE had higher odds of spending longer time on mechanical ventilation and spent significantly more days in the hospital.

Coronavirus disease 2019 (COVID-19) related chronic lung changes secondary to severe disease have become well known. The aim of this study was to determine the risk factors that affect the development of interstitial lung disease in subjects with COVID-19 pneumonia who were hospitalized. ⋯ Residual parenchymal disease was observed 3-6 months after discharge in one third of the subjects hospitalized with COVID-19 pneumonia. It was observed that interstitial lung disease developed more frequently in older men and in those subjects with more-severe disease parameters.
