Final answer:
Assisted ventilation may be discontinued when the patient's oxygen saturation levels are stable and within a normal range, and when the patient is able to maintain a consistent and adequate respiratory rate and volume of air per breath on their own.
Step-by-step explanation:
Assisted ventilation may be discontinued when:
- The patient's oxygen saturation levels are stable and within a normal range, indicating that their lungs are functioning adequately without the need for additional support.
- The patient is able to maintain a consistent and adequate respiratory rate and volume of air per breath on their own, demonstrating that their respiratory function has improved.
These are key indicators that the patient's respiratory function has improved sufficiently for assisted ventilation to be safely discontinued.
