BACKGROUND This study determined actual utilization rates and outcomes of noninvasive positive pressure ventilation (NIV) at selected hospitals that had participated in a prior survey on NIV use. METHODS This observational cohort study, based at eight acute care hospitals in Massachusetts, focused on all adult patients requiring ventilatory support for(More)
This paper presents the design and implementation of a performance-optimized LNA circuit targeted for UWB receivers. The systematic design of a CMOS distributed LNA circuit comprising cascode cells is illustrated. Each cascode cell employs an inductor between the common-source and common-gate devices to enhance the bandwidth, while reducing the(More)
BACKGROUND The prevalence of chronic disease and do-not-intubate status increases with age. Thus, we aimed to determine characteristics and outcomes associated with noninvasive ventilation (NIV) use for acute respiratory failure (ARF) in different age groups. METHODS A database comprising prospective data collected on site on all adult patients with ARF(More)
PURPOSE Few studies have examined locations of noninvasive ventilation (NIV) application for acute respiratory failure (ARF). We aimed to track actual locations of NIV delivery and related outcomes. METHODS Observational cohort study based at 8 acute care hospitals in Massachusetts on adult patients admitted for ARF requiring ventilatory support during(More)
