To the Editor:
Following publication of our article “Variability in mechanical ventilation: what's all the noise about?”1 an oversight has been brought to our attention. We erroneously stated that “There are no commercially available ventilators capable of performing variable ventilation.” However, the Evita Infinity V500 (Dräger, Lubeck, Germany) has a variable pressure support option. The percentage of desired variation (0–100%) is chosen with the pressure support range varying between pressure support + 100% and the set CPAP for the upper and lower limits, respectively.
