What would cause a high pressure alarm in a tracheostomy tube situation?

In a tracheostomy tube situation, a high pressure alarm is primarily triggered when there is a restriction in airflow due to obstruction. When a tracheostomy tube becomes lodged against the tracheal wall, it creates a significant barrier to airflow, leading to increased resistance in the system. This increased resistance causes the ventilatory pressure to rise, which will trigger the high pressure alarm on the ventilator or assisting device.

Proper troubleshooting would involve assessing the positioning of the tracheostomy tube to ensure that it is not kinked, occluded, or improperly placed. Identifying and correcting the cause of the obstruction can help restore normal airflow and eliminate the high pressure alarm.
