In which mode of ventilation does the patient receive a set number of mandatory breaths each minute while still being able to breathe spontaneously?

• A. Assist-controlled ventilation
• B. Continuous mandatory ventilation
• C. Continuous spontaneous ventilation
• D. Intermittent mechanical ventilation

Answer: (D)

The mode of ventilation that provides a set number of mandatory breaths each minute while allowing the patient to breathe spontaneously is known as Intermittent Mechanical Ventilation. This mode allows for a combination of both assisted and controlled breaths. In this setup, the ventilator delivers a predetermined number of breaths, ensuring a baseline level of support for the patient. However, it also permits the patient to initiate additional breaths on their own, which allows for spontaneous breathing efforts in between mandatory breaths.

This flexibility is beneficial for patients who may be recovering from respiratory issues but still require some mechanical support. It promotes better ventilatory drive and minimizes the risks associated with complete mechanical dependency, making it particularly useful in transitional phases of weaning from mechanical ventilation.

The other options do not accurately describe this combination of mandatory breaths and spontaneous breathing.
