Methodological and Clinimetric Evaluation of Inspiratory Respiratory Muscle Ultrasound in the Critical Care Setting: A Systematic Review and Meta-Analysis
Authors' conclusion
Diaphragm muscle ultrasound is reliable, valid, and responsive in ICU patients, but significant variation exists in the imaging acquisition and analysis methodologies.
Study context
- Population
- Adult ICU patients (studies enrolling at least 50) with respiratory muscle (diaphragm or intercostal) ultrasound
- Participants
- 5,025 patients · 60 studies
- Comparison
- Image acquisition and analysis methodologies of inspiratory respiratory muscle ultrasound
- Outcome
- Clinimetric properties of respiratory muscle ultrasound methodologies
