Which term describes a type of ventilator support where the machine partially assists breathing?

• A. Full support
• B. Partial support
• C. Spontaneous
• D. Intermittent weaning

Answer: (B)

Partial support describes a ventilator setup where the machine shares the work of breathing with the patient. The patient initiates each breath, and the ventilator provides a portion of inspiratory pressure or flow to augment that breath, making it easier to inhale while still allowing the patient to control rate and timing. This approach helps rest the respiratory muscles while maintaining their activity, which is useful during weaning or when the patient needs to work less hard to achieve adequate ventilation. An example is pressure support ventilation, where a preset inspiratory pressure boost is delivered during each inspiration. In contrast, full support means the machine does most or all of the work, spontaneous implies breaths occur with little or no assist from the ventilator, and intermittent weaning refers to alternating periods of support and unsupported breathing to test readiness, rather than describing a single partial augmentation.
