Point-of-Care Ultrasonography in Emergency and Critical Care Medicine

Chen, L., & Malek, T. (2018). Critical Care Nursing Quarterly, 41(2), 94-101. 10.1097/CNQ.0000000000000190
Abstract
To stabilize critically ill patients, emergency and critical care medicine providers often require rapid diagnosis and intervention. The demand for a safe, timely diagnostic device, alongside technological innovation, led to the advent of point-of-care ultrasonography (POCUS). POCUS allows the provider to gain invaluable clinical information with a high level of accuracy, leading to better clinical decision-making and improvements in patient safety. We have outlined the history of POCUS adaptation in emergency and critical care medicine and various clinical applications of POCUS described in literature.

Factors influencing weaning older adults from mechanical ventilation: An integrative review

Stieff, K. V., Lim, F., & Chen, L. (2017). Critical Care Nursing Quarterly, 40(2), 165-177. 10.1097/CNQ.0000000000000154
Abstract
This study aim was to describe the influences that affect weaning from mechanical ventilation among older adults in the intensive care unit (ICU). Adults older than 65 years comprised only 14.5% of the US population in 2014; however, they accounted up to 45% of all ICU admissions. As this population grows, the number of ICU admissions is expected to increase. One of the most common procedures for hospitalized adults 75 years and older is mechanical ventilation. An integrative review methodology was applied to analyze and synthesize primary research reports. A search for the articles was performed using the PubMed and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases; using the keywords and Boolean operators "older adults," "weaning," "mechanical ventilation," and intensive care unit. Although physiologic changes that occur with aging place older adults at higher risk for respiratory complications and mortality, there are many factors, other than chronological age, that can determine a patient's ability to be successfully weaned from mechanical ventilation. Of the 6 studies reviewed, all identified various predictors of weaning outcome, which included maximal inspiratory pressure, rapid shallow breathing index, fluid balance, comorbidity burden, severity of illness, emphysematous changes, and low serum albumin. Age, in and of itself, is not a predictor of weaning from mechanical ventilation. More studies are needed to describe the influences affecting weaning older adults from mechanical ventilation.
