WebDec 29, 2024 · The diaphragm and lung ultrasound variables are described in Table 2. Inspiratory diaphragmatic thickness and diaphragmatic thickening fraction increased moving from supine to prone position (inspiratory diaphragmatic thickness, p = 0.018; diaphragmatic thickening fraction p = 0.025). WebApr 24, 2024 · The diaphragm thickening fraction (TF) has been proposed as a surrogate criterion to estimate the breathing workload [ 16, 18 ], and was found as a predictor of weaning success in the ICU settings [ 19 ]. It has been recently shown to be correlated with diaphragm strength, independently of peripheral muscular strength [ 20, 21 ]. fluke 9141 dry well calibrator
