Article Snippet: Weekes et al . [ ] 2011 USA POS Comparison of Serial Qualitative and Quantitative Assessments of Caval Index and Left Ventricular Systolic Function During Early Fluid Resuscitation of Hypotensive Emergency Department Patients , Machine type: Index: Philips CX50 Floor-based US machine Transducer PA Reference: Recorded images and clips Windows: Not Described Method: Index: visual estimation and fractional shortening Reference: Not Described Categorization: increased function, normal function, reduced function, or severe dysfunction , Clinician sonographer: EPs number not Described Level of experience: not well described Emergency US division physicians Additional training: no standardized training. training on EPSS and the fractional shortening methods and on the details of image acquisition, technique, details of scoring criteria, and the sequence of measurements to standardize the protocol. , Convenience sample, n = 24 ED adult patients Inclusion: symptomatic hypotension systolic Blood pressure ≤100 mm Hg, sinus rhythm, the EP had intent to administer IV fluid challenges. Exclusion: unstable arrhythmia or CPR, suspected CHF, inability to obtain adequate quality US images, pregnancy, trauma, inability to tolerate the positioning, predictable ED stay of <45min. , Intervention: POC echocardiography by clinician sonographer Expert sonographer: videoclips. US EP fellowship Interval: N/A , Agreement between clinician sonographer and expert sonographer scan for visual estimation, n = 24 patients (72 scans): •κ = 0.46 (0.29–0.63) •κ w = 0.57 (0.41–0.72) •Overall agreement = 65.3% US scoring and measurements were performed at three defined points per enrolment. Time 0 was defined as the start of the fluid challenges. Time 1 was defined as immediately after the first fluid challenge. Time 2 was defined as 15–20 minutes after Time 1. Seventy-two videos of LVSF and caval index were obtained..
