US as early tool to detect diaphragmatic dysfunction
- @drmarcogarrone at #HRreloaded

POCUS is the most accessible way to investigate the diaphragm in critical care (patients may not be excited about swallowing an esophageal balloon)

apposition zone - diaphragm thickens with contraction
diaphragmatic zone - downward translational motion
- @drmarcogarrone at #HRreloaded

POCUS assessment of two components of diaphragm:
(1) thickness of diaphragm: linear probe on zone of apposition
(2) translational motion of diaphragm: convex probe to evaluate downward motion

diaphragm US is similar to cardiac US. nothing too special about the heart, really. 😉

numerous potential confounders to diaphragmatic ultrasonography (including positioning, effort, abdominal pressure, and lack of normative values in sick patients)
- @drmarcogarrone at #HRreloaded

could diaphragmatic US predict SILI? diaphragmatic ultrasound could provide a variety of physiologic parameters that are otherwise unavailable in non-intubated patients.

Marco is currently investigating the use of diaphragm ultrasound
