A patient develops acute hypercapnic respiratory failure due to muscle fatigue. Which of the following modes of ventilatory support would you consider for this patient?
I.assist-control ventilation with adequate backup
II.continuous positive airway pressure
III.synchronized intermittent mandatory ventilation with adequate backup rate
IV.bilevel pressure support by mask

All three modes of ventilatory support listed (assist-control ventilation, synchronized intermittent mandatory ventilation, and bilevel pressure support by mask) provide assistive ventilation which will help overcome the muscle fatigue causing hypercapnic respiratory failure. The adequate backup rate provided in options I and III will ensure that the patient is receiving adequate ventilation even if they cannot initiate their own breaths. Bilevel pressure support by mask in option IV will provide positive pressure during inspiration and a lower positive pressure during expiration, which can help optimize ventilation and oxygenation in patients with respiratory failure. Continuous positive airway pressure in option II may not be sufficient to overcome the patient's muscle fatigue, so it is not the best choice in this scenario.
