Which term describes a patient's spontaneous breath that is both pressure limited and flow cycled?

• A. Unsupported breath
• B. Triggered breath
• C. Assisted breath
• D. Controlled breath

Answer: (B)

The correct term for a patient's spontaneous breath that is both pressure limited and flow cycled is a triggered breath. In this context, a triggered breath occurs when the patient initiates a breath on their own (spontaneously) but is supported by a ventilator that delivers pressure when the patient takes a breath. The term "pressure limited" indicates that during this spontaneous breath, the ventilator controls the maximum pressure that can be delivered, which helps protect the lungs while allowing the patient to breathe in a way that is natural for them. The "flow cycled" aspect means that the breath is terminated when the ventilator detects the flow of air has decreased to a certain level, allowing for a more natural end to the breathing cycle based on the patient's own needs. This combination allows patients to have some autonomy in their breathing while still receiving the benefits of ventilatory support. The other terms do not accurately capture the characteristics of this type of breath; for instance, unsupported and controlled breaths do not involve the same supportive features from the ventilator.
