Which type of ventilation means all breaths are controlled and cannot be triggered by the patient?

• A. Spontaneous only
• B. Assist control ventilation
• C. Controlled ventilation
• D. Pressure control ventilation

Answer: (C)

Controlled ventilation refers to a mode in which all the breaths are delivered by the ventilator and cannot be initiated by the patient. In this mode, the ventilator is set to provide a specific number of breaths per minute, and if the patient attempts to initiate a breath, the ventilator does not respond. This makes it particularly suitable for patients who are unable to initiate breathing on their own due to sedation, neuromuscular diseases, or during surgical procedures. The primary focus in controlled ventilation is to ensure that the patient's breathing is fully managed by the ventilator, allowing for precise control over minute ventilation and overall respiratory support.
