➡️ Question
A 68-year-old female patient is receiving volume-controlled assist/control (A/C) ventilation. During your assessment, both the low tidal volume and high-pressure limit alarms sound with each inspiration. What should you do first?
A. Increase the preset tidal volume by 100 mL and reassess
B. Seek further instruction from the attending physician
C. Disconnect the patient and provide manual ventilation with an FiO₂ of 100%
D. Check the full patient-ventilator system for leaks and malfunctions

When faced with ventilator alarms, your first priority is to ensure that the patient is being adequately ventilated and oxygenated. Alarms indicating low tidal volume and high pressure suggest a problem with the ventilator circuit or the patient’s airway, such as an obstruction, increased resistance, or reduced lung compliance.

If the ventilator cannot deliver the set tidal volume, the patient is at risk of hypoventilation and hypoxemia. Immediate action must ensure adequate ventilation and oxygenation. When ventilator issues arise, disconnecting the patient and providing manual ventilation with 100% FiO₂ is the safest first step. This prevents delays in treatment while you troubleshoot the underlying issue. After ensuring the patient is stable, then you can examine the ventilator and circuit for possible causes, such as kinks, obstructions, or equipment malfunctions. Increasing the tidal volume is not appropriate because it does not address the root cause of the alarms and could worsen the situation if resistance or compliance issues exist.

While consulting with the physician is essential, it is not the immediate first step when alarms are sounding and the patient’s ventilation is compromised. Troubleshooting is necessary; however, it must occur after the patient is stabilized with manual ventilation. In cases where ventilator alarms are signaling potential patient compromise, your first action should always be to ensure that the patient is safely ventilated and along with adequate oxygenation. Manual ventilation with 100% FiO₂ is the safest and most effective initial response. Once the patient is stabilized, then you can proceed with identifying and resolving the cause of the ventilator alarms.
