What adjustment is necessary for the high pressure alarm before a fiberoptic bronchoscopy in a child receiving volume control ventilation?

Before performing a fiberoptic bronchoscopy in a child receiving volume control ventilation, it is essential to reset the high pressure alarm. This adjustment is necessary because the bronchoscopic procedure can lead to transient increases in airway resistance due to factors such as secretions, bronchospasm, or even the bronchoscope's presence in the airway. By resetting the high pressure alarm, the ventilator will be less likely to signal an alarm during these temporary conditions, allowing for smoother ventilation and management of the patient during the procedure.

This proactive step helps to avoid unnecessary interruptions or alarms that could detract from the care being provided, ensuring continuous monitoring without frequent disturbances that may arise due to the normal changes in airway dynamics occurring during bronchoscopy.
