Final answer:
Assist-control, Synchronized intermittent mandatory ventilation, and Pressure support ventilation can increase the client's work of breathing due to their varying levels of assistance provided during breathing cycles.
Step-by-step explanation:
Among the given modes of ventilation, Assist-control, Synchronized intermittent mandatory ventilation, and Pressure support ventilation can increase the client's work of breathing due to their varying levels of assistance provided during breathing cycles.
In Assist-control mode, the ventilator delivers a set number of breaths per minute and provides full assistance with each breath, both in terms of triggering the breath and delivering the tidal volume. This mode can increase the work of breathing as the ventilator is controlling the entire breathing cycle, and the patient may need to work harder to overcome the pressure and flow delivered by the ventilator.
In Synchronized intermittent mandatory ventilation (SIMV), the ventilator delivers a set number of breaths per minute, but the patient can trigger additional breaths. The assistance provided by the ventilator during the patient-triggered breaths may differ from the set breaths. This mode can also increase the work of breathing, as the patient needs to work harder during the patient-triggered breaths to overcome the resistance of the ventilator.
In Pressure support ventilation (PSV), the patient triggers each breath, and the ventilator provides assistance by delivering a preset pressure to support inspiration. However, the assistance provided during expiration varies. This mode can increase the work of breathing as the patient needs to generate sufficient force to overcome the resistance during expiration.
