What characterizes a high pressure alarm?

A high pressure alarm on a ventilator is characterized by an obstruction in the airway. This alarm typically indicates that the ventilator is encountering more resistance than normal while attempting to deliver breaths to the patient. This increased pressure can result from various factors such as secretions in the airway, bronchospasm, kinking of the tubing, or even patient-ventilator synchrony issues.

When this alarm activates, it prompts the healthcare provider to assess the patient for potential obstructions or complications. Addressing these issues is crucial to ensure that the patient receives adequate ventilation. Monitoring the high pressure alarm closely helps prevent patient harm and ensures optimal ventilator function.
