One-Year Functional Outcomes After Invasive Mechanical Ventilation for Older Adults With Preexisting Long-Term Care-Needs.
To examine 1-year functional outcomes after invasive mechanical ventilation for adults greater than or equal to 65 years with preexisting long-term care-needs. ⋯ Among patients in preexisting care-needs levels 2-5 who received invasive mechanical ventilation, 76.0-79.2% died or had worsened care-needs within 1 year. These findings may aid shared decision-making among patients, their families, and heath care professionals on the appropriateness of starting invasive mechanical ventilation for people with poor functional and cognitive status at baseline.

Randomized Controlled Trial
Lung-protective ventilation during Trendelenburg pneumoperitoneum surgery: A randomized clinical trial.
Study objective To assess the effects of a protective ventilation strategy during Trendelenburg pneumoperitoneum surgery on postoperative oxygenation. ⋯ In obese patients undergoing Trendelenburg pneumoperitoneum surgery, PV did not improve postoperative oxygenation nor day-2 respiratory function. PV was associated with intraoperative respiratory mechanics indicating less injurious ventilation. The high prevalence of complete airway closure may have affected study results.

The aim of this study was to assess the safety and efficacy of 2 protocols for automatic lung recruitment maneuvers (LRMs) using stepwise increases in PEEP in a neonatal ARDS model. These protocols were designed with lower maximum opening pressures than traditional methods and differ each one in the duration of the opening phases (short vs prolonged). We described hemodynamic changes through invasive monitoring, and we analyzed if the behavior of the variables depends on the duration of the opening phase of the LRM. ⋯ Our LRM protocols exceeded critical opening pressures to reverse alveolar collapse in our neonatal ARDS model. This range of pressures might involve less hemodynamic disturbance. Duration of the maximum opening pressure step is a determining factor for hemodynamic alterations.
