A 7 year old is being cared for at home with a ventilator. When you arrive, the ventilator alarm is going off. Your partner reports her pulse rate is 40. You should:

• A. Troubleshoot the settings
• B. Increase the volume of ventilations given by her machine
• C. Assist her ventilations with a BVM
• D. Increase the number of ventilations on machine

Answer: (C)

When a child on a ventilator has an alarm and a very slow pulse, the immediate priority is ensuring adequate ventilation. A bradycardic pulse in kids is often a sign of hypoxia, so you want to actively ventilate first to improve oxygen delivery. Use a bag-valve-mask attached to oxygen to provide breaths and assess chest rise while you quickly check the ventilator circuit for problems. This approach stabilizes breathing and buys time to troubleshoot the machine (checking connections, tubing, battery, and settings) without delaying ventilation. Increasing the machine’s volume or the number of breaths isn’t the best first move because it can cause overventilation or fail to address the underlying issue; manual ventilation allows immediate, controlled support and better assessment. If the patient’s condition worsens or there’s no pulse, escalate to CPR per protocol.
