Why is controlled ventilation less frequently used in clinical settings?

• A. It requires more resources
• B. It can cause patient discomfort
• C. It does not allow patients to trigger breaths
• D. It leads to overventilation

Answer: (C)

Controlled ventilation is characterized by the ventilator providing all breaths, without allowing spontaneous breathing from the patient. This mode can be necessary in certain clinical scenarios where strict control of ventilation is needed, such as during surgical procedures or in patients who are unable to breathe adequately on their own. However, one key reason for its less frequent use is precisely because it does not allow patients to trigger breaths. This can be problematic in terms of patient comfort and autonomy. Patients may experience feelings of stress or discomfort as they cannot initiate breaths themselves, which can lead to anxiety. Moreover, the inability to trigger breaths may not meet the respiratory demands of patients who have any capacity to breathe independently, potentially leading to adverse effects. Due to the limitations in allowing patient involvement in their own ventilation, controlled ventilation is typically reserved for specific situations where complete mechanical control is required. More commonly used modes, like assist-control or pressure support, allow patients to participate in their own breathing by triggering additional breaths if they choose to, promoting both comfort and better synchronization with the ventilator.
