- Abstract: Diaphragmatic function is central to respiration, and its evaluation is critical in intensive care unit (ICU) settings. Ultrasonography is a reliable bedside tool to assess diaphragmatic excursion (DE).[1,2] The conventional M-mode (MM) offers high-resolution imaging but requires precise alignment, which can be difficult in ICU patients.[3-5] Anatomical M-mode (AMM) allows flexible line adjustment, enabling accurate DE measurements despite poor acoustic windows.[6] However, comparative data between MM and AMM are limited. This retrospective study evaluated the concordance between MM and AMM for assessing right DE.
