Table 1 Ventilatory parameters, mechanical power, and lung ultrasound score over time, mean ± SD

Parameter (unit)	0 hours	24 hours	48 hours	72 hours
FiO₂ (%)	85.23 ± 16.56	78.18 ± 20.29	76.93 ± 21.89	73.63 ± 26.46
Tidal volume (mL)	355.34 ± 37.10	354.00 ± 31.80	350.68 ± 28.89	354.43 ± 34.05
Respiratory rate (per minute)	25.34 ± 4.30	26.05 ± 3.69	26.43 ± 4.66	26.91 ± 6.54
Minute ventilation (L/minute)	9.11 ± 1.94	9.22 ± 1.39	9.37 ± 1.53	9.99 ± 4.30
PEEP (cm H₂O)	10.27 ± 2.30	11.08 ± 2.56	11.38 ± 3.44	11.89 ± 4.50
Peak inspiratory pressure (cm H₂O)	30.09 ± 6.00	29.64 ± 6.90	30.05 ± 8.64	29.43 ± 10.86
Plateau pressure (cm H₂O)	26.77 ± 6.19	26.34 ± 6.72	26.68 ± 8.16	26.39 ± 10.49
Respiratory system compliance (mL/cm H₂O)	23.93 ± 8.08	26.53 ± 9.47	26.45 ± 10.41	28.93 ± 13.97
Driving pressure (cm H₂O)	16.63 ± 5.83	15.15 ± 5.06	15.28 ± 5.72	15.13 ± 6.67
Mechanical power (J/minute)	19.20 ± 4.84	19.99 ± 6.07	20.70 ± 7.92	21.76 ± 10.95
Lung ultrasound score	18.18 ± 4.40	19.18 ± 5.91	20.00 ± 7.91	20.43 ± 9.57

All values represent measurements from the entire study cohort (n = 44) at each time point. Values are presented descriptively to demonstrate temporal trends; no formal statistical comparisons across time points were performed, consistent with the exploratory study design. FiO₂: Fraction of inspired oxygen; PEEP: Positive end-expiratory pressure.
