An inhalant consisting of hyperoxic gas (95%-98% oxygen and 2%-5% carbon dioxide) with radiosensitizing properties. Inhaled carbogen reduces diffusion-limited tumor hypoxia, increasing tumor radiosensitivity due to the increased availability of molecular oxygen for cytotoxic radiation-induced oxygen free radical production. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
