Introduction: The number of vertical artefacts (VAs) in lung ultrasound (LUS) impacts patients' clinical management. This study aimed to demonstrate the influence of ultrasound settings on the number of VAs in patients under invasive mechanical ventilation (IMV).

Methods: Patients under IMV were recruited for LUS, including three breathing cycles with a motionless curvilinear probe on the thoracic region with the most VAs.

Article Synopsis
  • Spirometry is a test used to evaluate lung function by comparing it to normal levels in healthy non-smokers, focusing on metrics like forced vital capacity (FVC) and the FEV/FVC ratio.
  • The study analyzed data from over 14,000 participants aged 40 and older across 41 sites, revealing regional differences in FVC tied to factors like age and height, categorized into four regions: Europe/richer countries, Near East, Africa, and Far East.
  • Findings showed significant regional variations in FVC values between men and women, particularly in Europe compared to the Far East, but minimal differences in the FEV/FVC ratio across regions.

Objective: The aim of the work described here was to analyze the relationship between the change in ultrasound (US) settings and the vertical artifacts' number, visual rating and signal intensity METHODS: An in vitro phantom consisting of a damp sponge and gelatin mix was created to simulate vertical artifacts. Furthermore, several US parameters were changed sequentially (i.e.
