Pulmonary function test (PFT) impairments are common after allogeneic hematopoietic stem cell transplantation. The prognostic significance of these declines on outcomes is not well understood.The objectives were to determine the frequency of declines in pulmonary function (FVC, FEV1, and diffusing capacity for carbon monoxide [DLCO]) in the early post-transplantation period; and to determine the prognostic significance of these declines on mortality or development of bronchiolitis obliterans syndrome. ⋯ An absolute decline of ≥20% in FEV1, FVC, or DLCO were associated with reduced survival independent of pre-transplantation pulmonary function or relapse status. In contrast to previous work, early declines in PFT measures were not associated with future development of bronchiolitis obliterans syndrome.

Observational Study
Effects of the First Spontaneous Breathing Trial in Children With Tracheostomy and Long-Term Mechanical Ventilation.
Weaning and liberation from mechanical ventilation in pediatric patients with tracheostomy and long-term mechanical ventilation constitute a challenging process due to diagnosis heterogeneity and significant variability in the clinical condition. We aimed to evaluate the physiological response during the first attempt of a spontaneous breathing trial (SBT) and to compare variables in subjects who failed or passed the SBT. ⋯ Conducting an SBT to evaluate the tolerance and cardiorespiratory response in tracheostomized children with long-term mechanical ventilation is feasible. Time on mechanical ventilation before the first attempt and type of SBT (with or without positive pressure) could be associated with SBT failure.

Most ventilators measure airway occlusion pressure (occlusion P0.1) by occluding the breathing circuit; however, some ventilators can predict P0.1 for each breath without occlusion. Nevertheless, few studies have verified the accuracy of continuous P0.1 measurement. The aim of this study was to evaluate the accuracy of continuous P0.1 measurement compared with that of occlusion methods for various ventilators using a lung simulator. ⋯ The accuracy of continuous P0.1 measurements varies based on the characteristics of the ventilator and should be interpreted by considering the characteristics of each system. Moreover, measurements obtained with an occluded circuit could be desirable for determining the true P0.1.

Essential skills for respiratory therapists extend beyond the traditional scope of therapy. Respiratory therapists are expected to communicate effectively, deliver bedside education, and practice within interprofessional teams. Respiratory therapy entry-to-practice program accreditation standards require evaluation of student competence in communication and interprofessional practice. This study aimed to determine if entry into practice programs include curriculum and competency evaluation for oral communication, patient education, telehealth, and interprofessional activities. ⋯ Differences exist among program types for curriculum and competency evaluation. Telehealth was rarely included or evaluated at any degree level. Programs should evaluate the need for enhanced patient education and telehealth instruction.
