About this trial
Using mechanical ventilation for more than 18 hours can affect respiratory muscle and postural muscle control, making it difficult to wean off the ventilator and reducing mobility. The aim of this study is to:
1. Compare the effects of respiratory muscle strength training and early mobilization on dynamic lung compliance and maximum inspiratory pressure before and after a 7-day training period. 2. Compare the success rate of weaning and the duration of weaning between the respiratory muscle strength training and the early mobilization program.
Eligibility criteria
Qualifiers
Patients with respiratory diseases who have been on mechanical ventilation for more than 48 hours and are ready to be weaned off or undergoing weaning trials with continuous positive airway pressure (CPAP) or synchronized intermittent mandatory ventilation (SIMV).
The PaO2/FiO2 ratio is ≥ 150-200, with FiO2 ≤ 0.4-0.5 and PEEP ≤ 5-8 cmH2O, and a pH > 7.3 in blood plasma.
The age range is between 40 and 80 years old.
Patients exhibit good self-awareness and cooperation in training (Riker score of 4).
Disqualifiers
Clinical instability (HR > 120 beats/minute, RR > 30 breaths/minute, SatO2 < 90%, SBP > 140 mmHg or < 90 mmHg)
Patients who can be extubated and use non-invasive ventilation only or successfully extubated within the first 24 hours.
Patients with altered mental status (Glasgow Coma Score < 10) and inability to cooperate with training (Riker score < 4 or > 4)
Patients with limitations or contraindications such as inability to adjust the bed to a 45-degree angle or sit on the side of the bed, such as those with spinal cord injuries or recent head surgeries.
