The clinical approach to the critically ill patient has changed dramatically over the last several decades from one of deep sedation to that of mobilizing patients on mechanical ventilation and limiting sedation. The ABCDEF bundle is a multidisciplinary, evidence-based approach to the holistic management of critically ill patients that aims to optimize patient recovery, minimize iatrogenesis, and engage and empower the patient and family during their hospitalization. To achieve this goal, the bundle includes assessments for pain, delirium, and readiness to stop sedation and to start spontaneous breathing trials. ⋯ Performance of this bundle reduces mortality, ventilator days, intensive care readmissions, delirium, coma, restraint use, and discharge to facilities in a dose-dependent manner. The respiratory therapist, as a key member of the critical care team, is essential to the implementation, performance, and success of the ABCDEF bundle. This review aims to describe each component of the ABCDEF bundle, provide evidence for both the impact of individual interventions as well as the entire bundle, and detail the importance of this multidisciplinary approach to the care of the critically ill patient.

Randomized Controlled Trial
Targeted Lung Deposition From Nebulization Is Not Improved in the Lateral Decubitus Position in Healthy Volunteers.
Clinical benefits of inhaled therapies are related to the amount of drug deposited in the targeted area of the lung. Body positions that influence the distribution of lung ventilation should impact lung deposition of the nebulized drug. The aim of this study was to analyze the immediate effect of body position while the subject lies on his side (lateral decubitus) during nebulization on 3-dimensional total and regional lung deposition. ⋯ The total amount of drug delivered to the lungs during nebulization with an individual-controlled inhalation system tended to decrease when performed in the left lateral decubitus position. Moreover, contrary to the initial hypothesis, the deposition of particles in the dependent lung was not improved by the lateral decubitus position in this configuration.

New-generation ventilators display dynamic measures of respiratory mechanics, such as compliance, resistance, and auto-PEEP. Knowledge of the respiratory mechanics is paramount to clinicians at the bedside. These calculations are obtained automatically by using the least squares fitting method of the equation of motion. The accuracy of these calculations in static and dynamic conditions have not been fully validated or examined in different clinical conditions or various ventilator modes. ⋯ Automated displayed calculations of respiratory mechanics were not dependable or accurate in active breathing conditions. The calculations were clinically more reliable in passive conditions. We propose different methods of calculating Pmus, which, if incorporated into the calculations, would improve the accuracy of respiratory mechanics made via the least squares fitting method in actively breathing conditions.

There is limited knowledge of rapid-response (RR) events and code events for children receiving home mechanical ventilation (HMV) via a tracheostomy in a non-ICU respiratory care unit. The purpose of this study was to describe the demographic and clinical factors leading to deterioration among these children and to identify the incidence and outcomes following rapid-response and code events. ⋯ The overall incidence of RR/code events in children on HMV was higher than among non-HMV hospitalized children. Children on HMV preparing for their initial hospital discharge had the greatest number of RR/code events. The most prevalent interventions among children with RR events were ventilator setting adjustments, and among children with codes the most frequent actions were tracheostomy-related interventions. Developing strategies to predict risk factors for RR/code events may help decrease harm among children on HMV.
