Summary

There are many important principles related to ventilators, alarms, and safety features in the operating room and intensive care unit that are relevant to preparation for the American Board of Anesthesiology BASIX exam and anesthesiology training in general. The first part of this chapter is focused on ventilator management and begins with an overview of phase variables (trigger, limit, cycle). An introduction to non-invasive, controlled mechanical, and assisted mechanical modes of ventilation follows, along with relevant high-yield principles. The final section of the chapter provides an overview of alarm design and commonly tested safety features.
