Inclusion criteria

Inclusion criteria: 1. age 90%, positive end-expiratory pressure (PEEP) = 3 days and length of hospital stay >= 5 days as assessed by the attending physician; 7. informed consent from patient’s family members.

Exclusion criteria

Exclusion criteria: 1. receiving mechanical ventilation before ICU admission; 2. use of muscle relaxants during mechanical ventilation; 3. after cardiopulmonary resuscitation; 4. need for extracorporeal life support; 5. for children with severe acute respiratory distress syndrome, intervention should be implemented only when permitted by dynamic assessment of the attending physician; otherwise, exclusion applies; 6. presence of life-threatening organ failure such as liver or kidney failure requiring extracorporeal circulation.

Design outcomes

Primary

MeasureTime frame
Respiratory mechanics parameters of (pediatric patients) before intervention and at 1 min, 5 min, 15 min, and 30 min after intervention: ventilation mode, endotracheal tube inner diameter (cm), intubation depth (cm), airway resistance (Paw), dynamic lung compliance (Cydn), airway occlusion pressure (P0.1), P-V loop, tidal volume (Vt), total positive end-expiratory pressure (PEEPtot), peak airway pressure (Ppeak), plateau pressure (Pplat), intrinsic PEEP (PEEPi), and driving pressure (Pdriv =;Blood gas analysis parameters before and after intervention: arterial partial pressure of oxygen (PaO?), arterial partial pressure of carbon dioxide (PaCO?).;Sputum viscosity and sputum volume after expectoration.;Other indicators: duration of mechanical ventilation (h), PICU length of stay and total hospital length of stay (d), APACHE? score, CPIS score, PELOD-2 score.;
