Validation of a novel point-of-care ultrasound method to assess diaphragmatic excursion
Authors' conclusion
Our preliminary data from this exploratory study suggest that the evaluation of the excursion of the ZOA on the lateral aspect of the chest using a linear probe is consistently successful on both right and left sides.
Study context
- Population
- Elective surgical patients with normal diaphragmatic function, evaluated preoperatively
- Participants
- 75 patients
- Exposure
- Zone of apposition (ZOA) excursion vs dome of the diaphragm (DOD) excursion vs ZOA thickening fraction
- Outcome
- Successful evaluation of diaphragmatic excursion
Methodological detailssingle-centre, exploratory
