Monitoring of pulse pressure variation using a new smartphone application (Capstesia) versus stroke volume variation using an uncalibrated pulse wave analysis Monitor: a clinical decision making study during major abdominal surgery
Journal of Clinical Monitoring and Computing, 2019Co-Authors: Alexandre Joosten, Alexandra Jacobs, Olivier Desebbe, Luc Van Obbergh, Saxena Sarah, Joseph Rinehart, Alexander Hapfelmeier, Jean Louis Vincent, Bernd SaugelAbstract:Pulse pressure variation (PPV) and stroke volume variation (SVV) can be used to assess fluid status in the operating room but usually require dedicated advanced hemodynamic Monitors. Recently, a smartphone application (Capstesia™), which automatically calculates PPV from a picture of the invasive arterial pressure waveform from any Monitor Screen (PPV_CAP), has been developed. The purpose of this study was to compare PPV_CAP with SVV from an uncalibrated pulse wave analysis Monitor (SVV_PC). In 40 patients undergoing major abdominal surgery, we compared PPV_CAP with SVV_PC at post-induction, pre-incision, post-incision, end of surgery, and during every hypotensive episode (mean arterial pressure

do we perceive a flattened world on the Monitor Screen
Acta Psychologica, 2011Co-Authors: Fulvio Domini, Rajesh Shah, Corrado CaudekAbstract:Abstract The current model of three-dimensional perception hypothesizes that the brain integrates the depth cues in a statistically optimal fashion through a weighted linear combination with weights proportional to the reliabilities obtained for each cue in isolation (Landy, Maloney, Johnston, & Young, 1995). Even though many investigations support such theoretical framework, some recent empirical findings are at odds with this view (e.g., Domini, Caudek, & Tassinari, 2006). Failures of linear cue integration have been attributed to cue-conflict and to unmodelled cues to flatness present in computer-generated displays. We describe two cue-combination experiments designed to test the integration of stereo and motion cues, in the presence of consistent or conflicting blur and accommodation information (i.e., when flatness cues are either absent, with physical stimuli, or present, with computer-generated displays). In both conditions, we replicated the results of Domini et al. (2006): The amount of perceived depth increased as more cues were available, also producing an over-estimation of depth in some conditions. These results can be explained by the Intrinsic Constraint model, but not by linear cue combination.

An Applied Method for Estimating the Volume Median Diameter (VMD) of Droplet Generator: Sizing of Particle Image on Monitor Screen - การประยุกต์วิธีตรวจหาค่าปริมาตรขนาดละอองสาร Volume Median Diameter (VMD) ของเครื่องพ่นสารเคมีกำจัดแมลง
2014Co-Authors: Pongsakron Mukkhun, Phubeth Ya-umphan, Kasin SuphapathomAbstract:The method for estimating the volume median diameter (VMD) of droplet generator, by sizing of particle image on Monitor Screen, has been applied and validated. The magnesium oxide-coated slide samples were analyzed by using eyepiece microscope camera to output a digital image to a Monitor. Hand-drawn graticule, which was drawn and calibrated by comparing the stage micrometer scale, was used for measuring size of droplets. Data of droplet size classification was organized as an input file of the statistics software (Excel, SPSS), to reach volume median diameter. This method gives similar results and offers several advantages over conventional visual microscopic method. It's a good tool, less time consuming, for the operators who work for public health pesticide applicators Key words: pesticide applicator, volume median diameter (VMD), droplet size, particle sizing
