A 62-year-old ventilated ICU client with pneumonia is anxious and restless. The high-pressure alarm sounds, SpO2 falls from 95% to 90% and HR is 118. What are possible causes? (Select all that apply)

1. A kink in the ventilator tubing
2. The client biting the tube
3. Secretions needing suction
4. Disconnection from the ventilator
5. A leak around the cuff

Answer: A) A kink in the ventilator tubing, B) The client biting the tube, C) Secretions needing suction. High-pressure alarms mean increased resistance: secretions, biting, kinks, bronchospasm or fighting the ventilator. Disconnection and leaks cause low-pressure alarms.
