Brief summary

his study evaluates the diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement in intensive care unit patients, using chest radiography as the reference standard. Sensitivity and specificity of bedside ultrasonography will be calculated to assess its performance in this clinical setting.
