1) Potentially high work of breathing: In intermittent mandatory ventilation, patients have to initiate their own breaths during the weaning process. If the patient has a high work of breathing, they may struggle to initiate these breaths, leading to respiratory distress.
2) Weaning time possibly prolonged: Due to the patient having to initiate their own breaths, weaning may take longer as the patient's respiratory muscles may tire.
3) Patient-ventilator asynchrony: When the patient initiates a breath, it may not coincide with the ventilator's next mandatory breath, leading to asynchrony, which can cause patient discomfort and prolong weaning.
Therefore, options 1, 2, and 3 are all disadvantages of using intermittent mandatory ventilation for weaning, making option B the correct answer.
