Which assessment findings indicate a patient is ready to be weaned off mechanical ventilation? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply
1. Unstable hemodynamics
2. Rapid shallow breathing index of 40
3. A spontaneous tidal volume of 600 cc
4. An SaO2 of 95%
5. A respiratory rate of 18 on CPAP
3,4,5
Rationale 1: The patient must be hemodynamically stable before being weaned from mechanical ventilation.
Rationale 2: A rapid shallow breathing index of less than 105 indicates a readiness to wean from mechanical ventilation.
Rationale 3: A tidal volume of greater than 5 mL/kg indicates a readiness to wean from mechanical ventilation.
Rationale 4: An oxygen saturation of greater than 90% indicates a readiness to wean from mechanical ventilation.
Rationale 5: A respiratory rate of less than 35 indicates a readiness to wean from mechanical ventilation.
