The device uses a comprehensive suite of alarms to alert the operator and guide their actions to resolve the alarm condition and assure patient safety.

At the onset of an alarm, the screen displays the alarm name and then a series of context-sensitive help messages. These messages serve to guide the operator by presenting suggestions as to the cause and the resolution of a particular alarm. When multiple alarms occur they are prioritized and displayed based on the risk to the patient. Should the operator not be able to correct the problem, the ventilator should be taken out of use and sent to an authorized Impact repair facility.
