Abstract:
Objective To observe the influence of different altitudes on the basic vital signs of cardiopulmonary resuscitation (CPR) rescuers before and after CPR.Methods The experiment was completed in the Simulated Cabin for Special Environment of Northwest of China. Ninety healthy adult medical staff in General Hospital of Xinjiang Command were randomly and equally divided into 3 groups: plain (normal oxygen), 3700-meter high altitude and 4300-meter high altitude. According to the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, the values of heart rate (HR), mean arterial pressure (MAP), respiration rate (RR), arterial oxygen saturation (SpO2), before and after 1 CPR cycle were recorded for statistical analysis and their changes were compared.Results The HR and RR significantly increased (P<0.05), but MAP and SpO2 did not change significantly (P>0.05) in the three groups. The HR and RR was faster in 4300 meter high-altitude than in 3700 meter high-altitude (P<0.05), and was faster in 3700 meter high-altitude than in the plain (P<0.05). But there was no significant difference between the three groups in MAP and SpO2 (P>0.05).Conclusions With the elevation of the altitude, HR and RR may significantly increase in CPR rescuers, but there is no significant influence on MAP and SpO2.
