What happens if the ventilator cannot deliver the target tidal volume in PRVC?

• A. The patient automatically receives oxygen
• B. An alarm will sound
• C. The ventilator reverts to manual mode
• D. The settings must be adjusted immediately

Answer: (B)

In Pressure Regulated Volume Control (PRVC) mode, the ventilator aims to deliver a set tidal volume while adjusting the pressure to achieve this goal. If the ventilator is unable to meet the target tidal volume, it triggers an alarm as a safety measure to alert clinicians that the desired volume is not being delivered. This alarm is critical for patient safety, as it informs the healthcare team of potential issues such as increased airway resistance, decreased lung compliance, or equipment malfunction. This alarm acts as an important feedback mechanism, prompting the medical team to assess the patient's status and the functioning of the ventilator. Proper monitoring and response to such alarms are essential in ensuring effective ventilation and preventing respiratory complications.
