Tachypnea is a sign that the patient's work of breathing is too high to allow weaning to proceed. The patient's heart rate is within normal limits, although the nurse should continue to monitor it. An oxygen saturation of 91% is acceptable for a patient with COPD. A spontaneous tidal volume of 500 ml is within the acceptable range.
