Multicenter StudyTargeting occult heart failure in intensive care unit patients with acute chronic obstructive pulmonary disease exacerbation: Effect on outcome and quality of life.
To estimate the prevalence of previously undiagnosed heart failure in mechanically ventilated patients with severe exacerbation of chronic obstructive pulmonary disease (COPD) and to evaluate the impact of specific heart failure treatment on patients' outcome. ⋯ In mechanically ventilated patients with severe exacerbation of COPD, unrecognized left or right ventricular failure is common. Among patients with isolated left ventricular failure, the early detection and appropriate treatment improves long-term quality of life and may decrease the short- and 6-month morbidity and mortality.

Fundamental to respiratory care practice are airway management, noninvasive monitoring, and invasive mechanical ventilation. The purpose of this paper is to review the recent literature related to these topics in a manner that is most likely to have interest to the readers of Respiratory Care.

Observational Study
Long Term Acute Care Patients Weaning From Prolonged Mechanical Ventilation Maintain Circadian Rhythm.
Circadian rhythm regulates many physiologic and immunologic processes. Disruption of these processes has been demonstrated in acutely ill, mechanically ventilated patients in the ICU setting. Light has not been studied as an entraining stimulus in the chronically mechanically ventilated patient. The purpose of this study was to determine the association of naturally occurring ambient light levels in a long-term acute care (LTAC) hospital with circadian rhythm in patients recovering from critical illness and requiring prolonged mechanical ventilation (PMV). ⋯ Despite requiring continued high-level care and a prolonged stay in a medical facility, patients recovering from critical illness and actively weaning from PMV maintain their circadian rhythm in phase with normal diurnal variations of light.

Simple bedside predictors of mechanical ventilation in patients with Guillain-Barre syndrome.
The objective of the study is to develop and validate a predictor score for assessing the requirement of mechanical ventilation (MV) in patients with Guillain-Barre syndrome (GBS). ⋯ Several independent risk factors were found to predict the requirement for MV in patients with GBS at admission. However, after scoring and analyzing them, it was found that combining a few of them was more useful to predict the need for MV. A model using NSB score, developed using clinical variables, accurately predicted the requirement of MV. In addition, among the NSB score parameters, simple bedside SBC could adequately assess the adequacy of vital capacity.

Proportional assist ventilation plus (PAV+) applies pressure depending on the patient's inspiratory effort, automatically adjusting flow and volume assist to changes in respiratory mechanics. We aimed to assess the clinical factors associated with the success of PAV+ as first-line support in the acute phase of critical illness. ⋯ PAV+ proved feasible as first-line ventilatory support in 63% of the patients, mostly in individuals without extreme derangements in WOBTOT. Tachypnea and hypercapnia were the clinical factors associated with failure, though statistical significance was not reached.
