Which mode represents a combination of mechanical breaths with spontaneous breaths?

• A. Controller Mode
• B. Assisted control
• C. Synchronized Intermittent Mandatory Ventilation (SIMV)
• D. Constant Support Ventilation (CSV)

Answer: (C)

The choice that represents a combination of mechanical breaths with spontaneous breaths is Synchronized Intermittent Mandatory Ventilation (SIMV). In SIMV, the ventilator provides a set number of breaths, termed mandatory breaths, which are delivered at a preset tidal volume or pressure. In addition to these mandatory breaths, the patient can spontaneously breathe at their own rate and volume between or in addition to the mechanical breaths. This mode is particularly beneficial as it allows for patient-ventilator synchrony and can promote natural breathing effort, making it ideal for weaning patients off mechanical ventilation while still providing support. It helps to reduce the work of breathing for patients who may not be ready to sustain their respiratory needs completely on their own. Other modes listed do not convey the same blend of mandatory and spontaneous breathing. For instance, Assisted Control primarily delivers mandatory breaths triggered by the patient's effort but does not allow for independent, unassisted breaths in the same way. Understanding the distinction and functionality of these modes is crucial when managing patients who may need varying levels of respiratory support.
