A patient with ARDS who is receiving mechanical ventilation using synchronized intermittent mandatory ventilation (SIMV) has settings of fraction of inspired oxygen (FIO₂) 80%, tidal volume 500, rate 18, and positive end-expiratory pressure (PEEP) 5 cm. Which assessment finding is most important for the nurse to report to the health care provider?

The FIO₂of 80% increases the risk for oxygen toxicity. Since the patient's O₂saturation is 99%, a decrease in FIO₂ is indicated to avoid toxicity. The other patient data would be typical for a patient with ARDS and would not need to be urgently reported to the health care provider.
