Abstract:
Objective To investigate the changes of blood oxygen saturation and heart rate after urgently going to high‐alti‐tude area ,so as to provide a reference for medical rescue in high‐altitude area .Methods Subjects left from the plain area with an al‐titude of 400 m .Blood oxygen saturation and heart rate were measured before departure and after reaching 4 300 m altitude region . Then the subjects were taken to the destination with an altitude of 3 200 m ,at which they received a dynamic continuous monitoring of blood oxygen saturation /heart rate at the 1st day ,2nd day ,3rd day ,4th day ,5th day ,6th day ,7th day after arrival .After adapting to the environment in 3 200 m altitude area for 1 week ,subjects were taken to the 4 300 m altitude region ,at which they were re‐measured blood oxygen saturation and heart rate .Results After entering the areas of 4 300 m altitude and 3 200 m altitude ,the blood oxygen saturation was significantly decreased compared with that in plain area (P< 0 .05) .The blood oxygen saturation at the 6th and 7th day after entering 3 200 m altitude area was statistically different when compared with that at the 1st day(P< 0 .05) . The blood oxygen saturation had statistical difference between reaching at 4 300 m altitude area for the first time and re‐entering 4 300 m altitude area ,while the heart rate had no statistical difference (P> 0 .05) .Conclusion The arterial oxygen saturation was de‐creased with the increase of altitude ;the people living in plain areas can preliminarily adapt to the environment at 6th day after reaching 3 200 m altitude regions ;people can better adapt to the high‐altitude environment by shortly living in lower‐altitude areas before re‐entering high‐altitude areas .
