Management of Chronic Neuromuscular Respiratory Failure in the Intensive Care Unit.
In this seminar we describe the critical care management of patients with chronic neuromuscular diseases (cNMD). Determination of the acuity of the critical illness and trajectory of illness in the setting of cNMD is necessary to guide decision making. ⋯ Mechanical ventilatory support, whether noninvasive or invasive, requires redefinition of the goals of ventilation on a patient-by-patient basis. Mode and approach to invasive ventilation and liberation to noninvasive ventilation versus tracheostomy have limited evidence, but potential clinical approaches are reviewed.

Bronchoscopic lung volume reduction (BLVR) is an established treatment modality for the management of advanced chronic obstructive pulmonary disease complicated by severe emphysema and hyperinflation refractory to other therapies. BLVR aims to reduce hyperinflation and residual volume, thereby improving pulmonary function, symptom control, and quality of life. Multiple distinct devices and technologies, including endobronchial coils, thermal vapor ablation, bio-lung volume reduction, and airway bypass stenting, have been developed to achieve lung volume reduction with varying degrees of accessibility and evidence. ⋯ Additional new technologies may be able to improve the identification and evaluation of candidates as well as increase the portion of evaluated patients who ultimately qualify for BLVR. In this review, we aim to provide historical context to BLVR, summarize the available evidence regarding its use, discuss potential complications, and provide readers with a clear guide to patient selection and referral for BLVR, with a focus on EBV placement. In addition, we will highlight potential future directions for the field.

ReviewNavigating COPD in Aging Populations: Insights Into Pathophysiology and Comprehensive Care.
Chronic obstructive pulmonary disease (COPD) poses a significant and growing health burden among aging populations, marked by increasing prevalence and complex management challenges specific to elderly patients. This review explores the multifaceted interplay between COPD and aging, highlighting overlapping pathophysiological processes and comorbidities that complicate diagnosis and treatment. We examine age-specific management strategies, emphasizing the need for tailored approaches that account for the unique physical, cognitive, and health-related quality of life impacts on older adults. ⋯ The importance of integrative approaches to enhancing health care delivery is also underscored. Finally, we outline future directions, focusing on novel treatment pathways and the identification of biomarkers for early detection. Addressing these elements is essential for optimizing care in this vulnerable population and alleviating the significant societal and economic impacts of COPD among aging patients.

ReviewFuture Considerations and Areas for Innovation for Pulmonary Rehabilitation in Chronic Obstructive Lung Disease Patients.
Pulmonary rehabilitation is an effective therapy that improves day-to-day symptoms and quality of life in patients with chronic obstructive pulmonary disease. In this review, we look at the role of virtual programs, implementation of artificial intelligence, emerging areas of improvement within the educational components of programs, and the benefit of advanced practice providers in directorship roles.

ReviewPulmonary Vascular Disease in Chronic Obstructive Pulmonary Disease.
Pulmonary hypertension (PH) is a vascular disease characterized by pulmonary artery remodeling and right heart failure. PH related to COPD is a precapillary form of the disease, with hemodynamic measurements including a mean pulmonary artery pressure of greater than 20 mm Hg, a wedge pressure of less than 15 mm Hg, and a pulmonary vascular resistance of greater than 3 WU (Woods units), categorized under the World Health Organization classification as group 3. The presence of PH in COPD has been known to increase morbidity and mortality. Limited studies have evaluated treatment options for PH related to COPD.
