Die Rettungsflieger

When this series ran on GermanTV here in the US, both my husband and I liked it very much because we both loved anything to do with flying. So we found little to criticize. I liked it so much that, after the demise of GermanTV, I bought all 11 seasons of the series on DVD and have been watching most of them several times. I had noticed slight discrepancies in continuity when some things were done or said which were not compatible with events that had happened earlier. As I have no medical knowledge whatsoever, I cannot comment on the medical jargon used (for which I am glad), but in Episode 11 of the 10th season a really ridiculous mistake was made. According to police, rescuers and hospital personnel, a young couple who stayed overnight in their car was said to suffer from carbon dioxide poisoning. Carbon dioxide (CO2) is found in carbonated soft drinks as well as in beer, champagne and other alcoholic beverages. It is not poisonous. The toxic gas is carbon monoxide (CO) which becomes dangerous when an internal combustion engine or a stove is operated in an enclosed space with no ventilation. I find it difficult to imagine that neither the actors nor the staff noticed this mistake.
