The healthcare team is determining if a patient can be weaned from mechanical ventilation. Which of the following would determine that the patient could be weaned at this time?
1. hemoglobin level 8 mg/dL
2. urine output 500 cc/24 hours
3. oxygen saturation 89%
4. breathing rate less than 35 spontaneous breaths per minute
4
Rationale: One of the bedside weaning parameters is assessment of the patient's breathing rate. A breathing rate of less than 35 spontaneous breaths per minute would mean that the patient falls within the target range for weaning from the ventilator. The hemoglobin level needs to be 10 mg/dL or greater to fulfill successful weaning criteria. The urine output needs to be 620 cc/24 hours or greater to fulfill successful weaning criteria. The oxygen saturation needs to be 90% or greater to fulfill successful weaning criteria.
