Treatment of nitric oxide (NO) is becoming increasingly important in intensive transport flights Especially in the treatment of severe lung diseases, such as Covid-19, nitric oxide is now increasingly being used in intensive care units. The ÖAMTC air rescue has now reacted to this fact and equipped the intensive-care transport helicopter Christophorus 33 which is stationed in Wiener Neustadt, with a modern nitrogen monoxide breathing gas system. The mobile system from Messer Medical Austria GmbH and the company friema enables the rapid and precise addition of NO in the course of artificial ventilation during the intensive care transport flight. In this way, an uninterrupted NO therapy can be guaranteed for highly complex interhospital transfers of seriously ill patients. Just a few days after installation, the new system was used on a transfer flight of a patient with lung failure after a Covid-19 infection.
