Which scenario would trigger a high-pressure alarm on a ventilator?

A high-pressure alarm on a ventilator is typically triggered when there is an increase in resistance within the ventilation circuit or the patient's airways. In the scenario where the line is kinked or there is increased airway resistance, the ventilator experiences difficulty in delivering the set tidal volume to the patient. This increased resistance results in a rise in pressure, prompting the ventilator to activate the high-pressure alarm as a warning to the healthcare provider.

When clinicians understand that increased airway resistance or obstructions lead to this alarm, they can promptly investigate and resolve the issue, ensuring proper ventilation and patient safety.
