TF—thickening fraction; Tdi—diaphragm thickness; PEEP—positive end-expiratory pressure; VIDD—ventilator-induced diaphragmatic dysfunction.
WebThe change in diaphragmatic thickness (ΔTdi) during spontaneous breathing from functional residual capacity (FRC) to tidal volume (Vt) is called diaphragmatic thickness fraction (DTF) [ 22 ]. It was calculated using the formula: (end-inspiratory DT – end expiratory DT)/end expiratory DT × 100.

WebDec 30, 2024 · Diaphragm thickening fraction was calculated as the ratio between diaphragm thickness at deep inspiration and end expiratory diaphragm thickness. Diaphragmatic mobility was measured with a 3.5-MHz ... WebApr 2, 2024 · The diaphragmatic thickening ratio reflects the diaphragm’s contractile capacity that is related to its strength [ 8 ]. Moreover the efficiency of diaphragm contractions can be assessed via DT and diaphragm thickness fraction (DTF) measurements, obtained during the expiratory and inspiratory phases of respiration [ 9 ].
WebMar 20, 2024 · Diaphragmatic thickness (Tdi) and diaphragm thickening fraction (dTF) are widely used parameters in ultrasound studies of the diaphragm in mechanically ventilated children, but normal values for healthy children are scarce.
