What is a potential risk associated with Continuous Mandatory Ventilation (CMV)?

• A. Increased cooperation from the patient
• B. Results in decreased work of breathing
• C. Impairment of effective spontaneous breathing
• D. Encourages independent respiratory pattern

Answer: (C)

Continuous Mandatory Ventilation (CMV) is a mode of ventilation that provides a set number of mandatory breaths regardless of the patient's own efforts. This can lead to the potential risk of impairing effective spontaneous breathing. When patients rely heavily on the ventilator to provide the mandatory breaths, their own respiratory drive may diminish. As a result, they may not engage their respiratory muscles effectively, leading to muscle deconditioning and potentially compromising their ability to breathe spontaneously when the ventilator support is removed. This mode is beneficial in some circumstances, especially in patients who are unable to maintain adequate ventilation, but it may not promote the kind of respiratory muscle activity and independence needed for recovery. In contrast, modes that encourage or allow for spontaneous breathing can help maintain the patient's respiratory muscle strength and support better overall respiratory function.
