patients under mechanical ventilation.
Conditions
Interventions
Intervention 1: Intervention group: In this group, pressure support is adjusted to the extent that the patient's rapid shallow breathing index is less than 105 breaths per minute per liter, because wh
this means that the patient's pressure support is set correctly.
