目的 评价自行设计的立位耐力监测系统的稳定性和重复性。方法 应用自行设计的立位耐力监测系统对28例健康歼击机飞行员进行立位耐力监测,间隔一周时间分别在相同条件下做相同的试验。结果 在两次立位耐力试验中平卧位、立位即刻、1 min、2 min、3 min、4 min、5 min、10 min、15 min和20 min各时间心率、收缩压、舒张压和平均动脉压比较差异均无显著性意义(P>0.05)。结论 自行设计的立位耐力监测系统稳定、可靠。
Objective To evaluate the stability and repeatability of a self-designed standing endurance monitoring system. Methods The standing endurance monitoring system designed by ourselves was used to monitor the standing endurance of 28 healthy fighter pilots in the same condition with one week apart. Results The heart rate, systolic pressure, diastolic pressure and diastolic blood pressure at supine position, stand immediately, 1 min, 2 min, 3 min, 4 min, 5 min, 10 min, 15 min and 20 min Mean arterial pressure was no significant difference (P> 0.05). Conclusion The self-designed standing endurance monitoring system is stable and reliable.
