The dynamic occlusion test is used to guide balloon catheter placement during esophageal pressure (Pes) monitoring. We introduced a cardiac cycle locating method to attenuate the influence of cardiac artifacts on Pes measurement. The aim was to provide a reliable analytic algorithm for the occlusion test. ⋯ The cardiac cycle locating method provided reliable and precise measurement for the occlusion test. This method can accurately detect non-optimal balloon position during catheter adjustment.

Development and Feasibility of a Home Pulmonary Rehabilitation Program With Health Coaching.
Pulmonary rehabilitation (PR) is an effective intervention for COPD. However, traditional center-based PR programs suffer from low uptake. Home-based PR is a viable solution, but few studies have shown the effectiveness of remote PR, as there is a scarcity of systems that can be easily adopted in clinical practice. The aim of this report is to communicate the development and feasibility of a home PR program that includes commercially available technology that allows the PR health coach to follow the patient through his or her PR process and to present the design of a prospective clinical trial. ⋯ A home PR program was developed that integrated health coaching and a home PR system that facilitated remote monitoring. Pilot testing indicated that the program is well-developed and feasible in a population of individuals with COPD. (ClinicalTrials.gov registration NCT02999685.).

Randomized Controlled Trial
Mechanical Insufflation-Exsufflation Versus Conventional Chest Physiotherapy in Children With Cerebral Palsy.
The cough mechanism is often impaired in children with quadriplegic spastic cerebral palsy, accounting for the high prevalence of pneumonia and atelectasis requiring prolonged hospitalization. Conventional chest physiotherapy (CPT) is a current technique recommended at the onset of lower-respiratory infections in cerebral palsy. Previous studies have demonstrated the usefulness of mechanical insufflation-exsufflation (MI-E) in children with neuromuscular disease. To date, there has been no study of MI-E in children with quadriplegic spastic cerebral palsy. The objective of the study is to compare the efficacy in reducing hospital stay and improvement of atelectasis between MI-E and CPT in children with quadriplegic spastic cerebral palsy with lower-respiratory infections. ⋯ MI-E is proven to be beneficial in shortening the duration of airway clearance in children with quadriplegic spastic cerebral palsy presenting with lower-respiratory infections and atelectasis. MI-E is a safe and efficient intervention for airway clearance.

Extracorporeal membrane oxygenation (ECMO) is used as a rescue therapy before and after lung transplantation, but little is known about functional recovery or complications after ECMO in this cohort. This study aimed to describe early physical function and leg complications in subjects who received ECMO before or after lung transplantation, and to compare functional outcomes to a matched cohort of subjects who did not require ECMO. ⋯ In subjects requiring ECMO before or after lung transplantation, 82% survived to hospital discharge, but leg complications were common and physical function was poor at ICU discharge. Physical function improved over time, however subjects who required ECMO had a longer period of hospitalization and worse physical function at ICU and hospital discharge than those who did not require ECMO.

Esophageal balloon inflation volume may affect the accuracy of transpulmo-nary pressure estimates in adults, but the effect is unknown in pediatrics. Using a combination bench and human study, we sought to determine a range of optimal filling volumes for esophageal balloon catheters and to derive a technique to inflate catheters to yield the most accurate estimates of pleural pressure. ⋯ Manufacturer-recommended esophageal balloon inflation ranges do not assure accuracy. Individual titration of esophageal balloon volume may improve accuracy. Better esophageal catheters are needed to provide reliable esophageal pressure measurements in children.
