Point of Care Ultrasound (POCUS) - Basics Nomenclature: - Echogenicity = brightness - Hyperechoic = more echogenic (brighter) than surrounding tissue - Isoechoic = equal echo brightness to surrounding tissues - Hypoechoic = less echogenic (darker) than surrounding tissue - Anechoic = devoid of echoes (iet black) Knobology - DAG: - DEPTH- can increase or decrease viewing depth. Always limit depth to center image if interest on screen - AXIS- moving the probe to center the image in the Y axis - GAIN- Contrast/Resolution/Brightness of image #pocus #ultrasound #knobology #basics
