Open Access Abstract Introduction Critically ill patients suffer from oxidative stress caused by reactive oxygen species ROS and reactive nitrogen species RNS . Although ROS RNS are constantly produced under normal circumstances critical illness can drastically increase their production.

The pro-oxidant antioxidant balance is of functional relevance during .
