What could cause a patient to trigger the ventilator in PAug mode?

• A. A decrease in oxygen levels
• B. Patient effort during inhalation
• C. Unexpected power outage
• D. Adjusting the ventilator settings

Answer: (B)

In pressure assist/control ventilation (PAug mode), the ventilator is responsive to both preset settings and patient triggers. The patient can initiate a breath through their own efforts during inhalation, which is the primary mechanism that allows them to trigger the ventilator. When a patient takes a breath that generates negative pressure, the ventilator recognizes this effort and initiates the assisted breath, delivering air to the patient to support their breathing needs. This mode combines the patient's spontaneous effort with the ventilator's controlled support, making it ideal for patients who are able to initiate breaths but require assistance to ensure adequate ventilation. Conditions like a decrease in oxygen levels, unexpected power outages, or adjustments to ventilator settings do not directly cause a patient to trigger the ventilator. Instead, they may influence overall patient management and may require different interventions. Thus, patient effort during inhalation is the key factor that enables triggering in this mode.
