CPAP benefits preterm infants with respiratory distress, including reduced bronchopulmonary dysplasia (BPD) incidence, surfactant use, and extubation failure. Successful CPAP weaning also promotes oral feeding. However, there is no consensus on the optimal weaning of CPAP in neonates. This study aimed to determine the effects of CPAP weaning guideline implementation on neonatal outcomes. ⋯ The implementation of the bubble CPAP weaning guideline improved the successful weaning of CPAP and promoted oral feeding in preterm infants.

Transnasal fiberoptic laryngoscopy (TFL) has revealed that laryngeal obstruction can hamper assisted ventilation. TFL may be considered invasive, and laryngeal ultrasound (US) could be a noninvasive alternative. The objective of this study was to investigate the feasibility of using laryngeal US to study laryngeal movements in healthy adult volunteers undergoing noninvasive ventilation (NIV) and to compare the observations with those of simultaneous TFL. ⋯ Laryngeal US emerged as a feasible method to describe laryngeal movements during NIV, providing high-quality observations and high concordance with TFL.

The global population is aging, and the proportion of elderly patients admitted to Intensive Care Units (ICUs) is increasing. In this scenario, achieving a balance between judicious utilization of a limited and high-cost resource and providing optimal intensity of care presents a challenge, given that in very elderly patients, the value of ICU care is uncertain. The aim of our study is to evaluate the survival of older patients admitted to ICU who require mechanical ventilation (MV) at different levels of treatment intensity. ⋯ Our data indicate that in older subjects using MV, higher intensity of treatment does not seem to translate into a survival benefit. This finding highlights the importance of considering individualized treatment plans for elderly patients in the ICU.

Assessing respiratory mechanics in patients with acute hypoxemic respiratory failure who are not intubated could provide useful information about illness trajectory. Oscillometry is a respiratory function test used to measure total respiratory impedance during tidal breathing, which reveals resistive and elastic properties of the lung. This study assessed the feasibility of oscillometry in patients with acute hypoxemic respiratory failure and described their respiratory mechanics. ⋯ Respiratory mechanics in the participants with acute hypoxemic respiratory failure who were not intubated could be assessed by oscillometry in carefully selected cases.

The understanding of how pharyngeal pressure is transmitted to the trachea with high-flow nasal cannula (HFNC) implementation and the behavior of tracheal pressure in the presence of mouth leaks remains limited. This study aimed to assess the impact of HFNC administration on tracheal pressure by comparing measurements taken with open and closed mouth with varying flows. ⋯ The implementation of HFNC changes airway pressures with values that impact at a tracheal level as the flow used increases. Our data contribute to the difficult interpretation of the existing interrelation between the programmed flow and its effects on the respiratory system.
