Case Description
Oxygen Toxicity and Conservative Oxygen Therapy in Critical Illness highlights the risks of excessive oxygen administration in critically ill patients. While oxygen is essential for life, high concentrations over prolonged periods can lead to oxidative stress, lung injury, and worsened outcomes,...
Case Summary
- Oxygen, though vital for life, can be toxic at higher concentrations. Oxygen therapy, defined as administering oxygen above the normal 21% room air concentration, can lead to hyperoxia and subsequent oxygen toxicity or poisoning. While mitochondria are adapted to lower oxygen levels, other cellular systems are sensitive to hypoxemia, necessitating external oxygen supply in cases of illness-induced oxygen reduction.
