The ICU therapist responds to an alarm on the ventilator. What is the most appropriate immediate action?

• A. Document the Alarm in the Chart
• B. Ensure the Patient Is Being Ventilated
• C. Reprogram the Ventilator Settings
• D. Call the Supervisor

Answer: (B)

The immediate priority when a ventilator alarm sounds is to confirm the patient is still being ventilated. An alarm can signal something as simple as a circuit disconnection or obstruction, and the first action is to verify airflow to the patient.

Quickly assess by checking the patient and the circuit: observe chest movement, listen for breath sounds, feel for air at the endotracheal tube, and look at the ventilator’s status display. If ventilation isn’t occurring, provide manual ventilation with a bag–valve mask and fix the circuit or source of the problem right away. If the patient is still being ventilated but the alarm continues, begin troubleshooting the circuit and settings after ensuring ongoing ventilation.

Documenting the alarm, reprogramming settings, or calling a supervisor are important steps, but they come after establishing that the patient is being ventilated and securing ventilation.
