This review will provide a guide to ventilator management to aid the ED physician. Pulmonary physiology and adverse effects of artificial ventilation on the pulmonary system will be discussed. Assist control ventilation is the most common mode of ventilation and should be used initially for patients in the ED. Pitfalls of therapy and troubleshooting the ventilator will be reviewed, recognizing that the respiratory therapist is a valuable reference and capable of handling the majority of mechanical ventilation issues.
