What is the initial action for a high-pressure alarm on a ventilator?

• A. Check for kinks or obstructions in tubing
• B. Disconnect the patient from the ventilator
• C. Increase the tidal volume
• D. Administer a bronchodilator

Answer: (A)

When a high-pressure alarm sounds on a ventilator, the first action is to inspect the ventilator circuit for kinks or obstructions in the tubing and to verify all connections are patent. These issues are common and quickly reversible causes of elevated airway pressure. If you find a kink or blockage, clear it or replace the circuit and suction the patient if needed. If the circuit is clear and the alarm persists, reassess for other problems like bronchospasm or mucus plugging and address them accordingly. Increasing tidal volume or disconnecting the patient from the ventilator are not appropriate initial steps, and bronchodilators are considered after ruling out circuit obstruction.
