Question

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
a.II and IV
b.III and IV
c.I, II, and III
d.I, III, and IV

Answer 1

For a patient with acute hypercapnic respiratory failure due to muscle fatigue, options II (continuous positive airway pressure) and IV (bilevel pressure support by mask) would be appropriate.

Step-by-step explanation:

A patient who develops acute hypercapnic respiratory failure due to muscle fatigue may require ventilatory support. In this case, options II (continuous positive airway pressure) and IV (bilevel pressure support by mask) would be considered. Continuous positive airway pressure (CPAP) provides a constant level of pressure throughout the respiratory cycle, which helps keep the patient's airways open and improves oxygenation. Bilevel pressure support provides two levels of pressure, higher during inspiration and lower during expiration, to assist with breathing in patients experiencing respiratory failure.
