Dr. Leon Chen is a board certified Adult/Gerontology Acute Care Nurse Practitioner with background in emergency and critical care medicine. He holds specialty board certifications in both emergency and critical care nursing. With extensive experience in invasive procedures and advanced resuscitation methods, he is also a strong proponent of utilizing point of care ultrasonography to rapidly delineate differential diagnoses and to guide resuscitation. Having earned a certificate of completion in critical care ultrasonography from the American College of Chest Physicians, Dr. Chen is active in critical care ultrasonography education and aside from teaching NP/PA, resident physicians and critical care fellows at the bedside, he has also been a course planner/faculty for the annual critical care ultrasound workshop for NP/PA and MDs held at Memorial Sloan Kettering Cancer Center since 2016. He has also created an ultrasound training curriculum for critical care NP and PAs at Memorial Sloan Kettering Cancer Center and serves as a liaison between Cardiology and Critical Care Medicine Service to streamline critical cardiac diagnosis and management. Dr. Chen has numerous publications in peer reviewed journals on the topics of sedation, delirium, sepsis, resuscitation and critical care ultrasonography and is currently an Editorial Board Member of the journal Critical Care Nursing Quarterly. Finally, Dr. Chen has been an adjunct clinical instructor/ACNP preceptor for NYU since 2013 and is a frequent speaker at institutional critical care forums and professional organizations’ educational symposiums and conferences. Dr. Chen hopes to bring his clinical experience to NYU Rory Meyers College of Nursing and incorporate point of care ultrasonography teaching into the ACNP program.

Point-of-Care Ultrasonography in Emergency and Critical Care MedicineAbstractTo 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 reviewAbstractThis 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.

Don't go chasing waterfalls excessive fluid resuscitation in severe sepsis and septic shockAbstractAggressive fluid resuscitation is the mainstay therapy in modern sepsis management. Its efficacy was demonstrated in the landmark study by Emmanuel Rivers in 2001. However, more recent evidence largely shows that a positive fluid balance increases mortality in critically ill patients with sepsis. This article examines the theoretical benefits of fluid resuscitation and physiological responses to it that may negatively affect patients' outcome.
