Endotracheal intubation is a routinely performed procedure in the ICU. Whereas it is recognized that endotracheal intubation can result in laryngeal and tracheal injury, this study evaluated factors that may affect the incidence of posterior vocal cord ulcers (PVCUs). ⋯ Earlier tracheostomy placement was associated with reduced severity of vocal cord ulcer formation. The Kaplan-Meier model suggests that waiting for 14 d is likely too long and earlier placement of a tracheostomy, within a week, may decrease the morbidity of posterior vocal cord injury.

Respiratory therapists (RTs) provide many types of patient care in different clinical settings. Burnout can have an undesirable effect on RTs and their patients. Managing the COVID-19 pandemic, specifically in hospitals, could induce stress in RTs and increase the likelihood of burnout. Therefore, this study aimed to measure the level of burnout among RTs during the COVID-19 pandemic. ⋯ A high prevalence of burnout was observed among RTs in one Saudi tertiary hospital. Burnout is associated with several factors, and interventions should target all domains of burnout. RT management and staff are responsible for addressing their needs and collaboratively working together to overcome burnout. Further investigations focusing on techniques and strategies to alleviate burnout are required.

Driving pressure (ΔP) and mechanical power (MP) may be important mediators of lung injury in ARDS; however, there is little evidence for strategies directed at reducing these parameters. We applied predictive modeling to estimate the effects of modifying ventilator parameters on ΔP and MP. ⋯ This novel conditional modeling confirmed expected response patterns for ΔP, with the response to adjustments depending on subjects' lung mechanics. Furthermore, a VT-driven approach should be favored over a breathing frequency-driven approach when aiming to reduce MP.

Direct Extubation to High-Flow Nasal Cannula versus Noninvasive Ventilation in Obese Subjects.
Patients who are obese have a higher risk of acute respiratory failure after extubation in the ICU. This study aimed to compare the extubation of subjects who were critically ill and obese to high-flow nasal cannula (HFNC) versus noninvasive ventilation (NIV) to determine whether HFNC can aid in reducing postextubation respiratory failure and the re-intubation rate. ⋯ Postextubation application of HFNC may prevent respiratory failure in patients who are obese.
