Distribution of patients in the mechanical ventilation process according to the mode of ventilation at enrollment

Study algorithm Group	Mechanical ventilation phase	Patients with ACV n (%)	Patients with PSV n (%)	p value
Not ready for weaning group	Recovery	19 (46)	118 (36)	0.211
ZERO CPAP tolerance and SBT failure groups	Weaning	11 (27)	128 (40)	0.119
SNR Group	Liberation	11 (27)	79 (24)	0.724

ACV: assist control ventilation, CPAP: continuous positive airway pressure, PSV: pressure support ventilation, SBT: spontaneous breathing trial, SNR: screened and non-randomized
