of the two antihistamines reduced the blood flow that occurs during recovery by 80 percent. The study, funded by the American Heart Association, was posted online ahead of regular publication in the Journal of Applied Physiology. While fainting aft...
'Sewer gas' induces suspended animation without decreasing blood pressure
...something they did not expect. Normally, as oxygen consumption
goes down and heart rate decreases, blood pressure decreases also. Since the heart rate of the mice fell by more than 50%, the researchers expected blood pressure to fall, but it didn't, Ichinose said. Surprisingly, blood pressure stays normal ...
