Understanding vital-sign abnormalities in critical care patients

چکیده
The number of avoidable cardiac arrests and unplanned admissions to ICU in step-down units (SDUs) remains too high. We have previously shown how a data fusion index, based on the integration of vital signs continuously monitored in SDUs, can identify the cardio-respiratory instability which often precedes these adverse events [1]. We show how the correlations between vital signs, captured in a data fusion index based on a probabilistic model of normality [2], change during times of cardiorespiratory instability.

INTRODUCTION Triage of patients is critical to patient safety, yet no clear information exists as to the utility of initial vital signs in identifying critically ill older emergency department (ED) patients. The objective of this study is to evaluate a set of initial vital sign thresholds as predictors of severe illness and injury among older adults presenting to the ED. METHODS We reviewed a...

INTRODUCTION The survival of patients admitted to an emergency department is determined by the severity of acute illness and the quality of care provided. The high number and the wide spectrum of severity of illness of admitted patients make an immediate assessment of all patients unrealistic. The aim of this study is to evaluate a scoring system based on readily available physiological paramet...
