Observational StudyAssessment of different computing methods of inspiratory transpulmonary pressure in patients with multiple mechanical problems.
While plateau airway pressure alone is an unreliable estimate of lung overdistension inspiratory transpulmonary pressure (PL) is an important parameter to reflect it in patients with ARDS and there is no concensus about which computation method should be used to calculate it. Recent studies suggest that different formulas may lead to different tidal volume and PEEP settings. The aim of this study is to compare 3 different inspiratory PL measurement method; direct measurement (PLD), elastance derived (PLE) and release derived (PLR) methods in patients with multiple mechanical abnormalities. 34 patients were included in this prospective observational study. ⋯ There was a good aggreement and there was no bias between the measurements in Bland-Altman analysis. The estimated bias was similar between the PLD and PLE (- 3.12 ± 11 cmH2O) and PLE and PLR (3.9 ± 10.9 cmH2O) measurements. Our results suggest that standardization of calculation method of inspiratory PL is necessary before using it routinely to estimate alveolar overdistension.

Recent observational studies of nebulizers placed on the wet side of the humidifier suggest that, after some time, considerable condensation can form, which triggers an occlusion alarm. In the current study, an inline breath-enhanced jet nebulizer was tested and compared in vitro with a vibrating mesh nebulizer on the humidifier dry-inlet side of the ventilator circuit. ⋯ Aerosol delivery during continuous infusion and bolus delivery was comparable between the inline breath-enhanced jet nebulizer and the vibrating mesh nebulizer, and was determined by pump flow and initial ventilator settings. Further adjustments in ventilator settings did not significantly affect drug delivery. Expiratory losses predicted by the duty cycle were reduced with placement of the nebulizer near the ventilator outlet.

Acute respiratory failure requiring invasive mechanical ventilation is a common presentation in the emergency department. Providers can further improve care for these patients by understanding common modes of mechanical ventilation, recognizing changes in respiratory mechanics, and tailoring ventilator settings and therapies accordingly.

Case ReportsImpact of COVID-19 on Patient-Provider Communication in Critical Care: Case Reports.
Communication impairment during mechanical ventilation and prolonged critical illness is extremely frustrating and frightening for patients and increases the risk for miscommunication, misinterpretation, and poor outcomes. The COVID-19 pandemic amplified patient communication impairment in intensive care units. This article presents 3 case examples from the experience of a team of hospital-based speech-language pathologists providing augmentative and alternative communication support resources and services to intensive care unit patients treated for COVID-19 during the first wave of the pandemic. Cases were selected to illustrate the protracted and complex in-hospital and rehabilitative recovery of critically ill patients with COVID-19, necessitating creative problem-solving and nursing collaborations with speech-language pathologists to support patient-provider communication. ⋯ Evaluation by augmentative and alternative communication specialists and progressive intervention from speech-language pathologists in collaboration with intensive care unit nurses can greatly improve patient-provider communication during treatment for and recovery from COVID-19 and other prolonged critical illnesses.
