Which of the following indicate that an adult patient is ready to be weaned from ventilatory support?
1) VC = 1.9 L
2) Spontaneous rate of 32/min
3) Q_s/Q_t = 8%
4) MIP = -45 cm H₂O

1) A vital capacity (VC) of 1.9 L is generally considered adequate for weaning, as it suggests sufficient respiratory muscle strength. 3) A low QS/QT (shunt fraction) of 8% indicates good lung function, suggesting the patient may not need as much support. 4) A maximal inspiratory pressure (MIP) of -45 cm H2O is strong, indicating good respiratory muscle strength, important for weaning.
