摘要
目的观察0.15 MPa高压氧干预下某省海军青少年航空学校学生的自主神经功能变化规律,为青少年群体的健康维护提供参考。方法选择自愿参加的42名海军青少年航空学校学生作为研究对象。高压氧干预采用空气加压5 min到0.15 MPa,停留60 min,持续面罩呼吸纯氧,5 min减至常压出舱。每周1次,连续7周。高压氧干预前后采集心电图,采用频域分析法获取心率变异性数据,分析干预前后自主神经功能的变化。结果0.15 MPa高压氧干预后,参试者最快心率由(89.81±15.40)次/min降至(84.44±15.36)次/min,最慢心率由(58.02±8.49)次/min降至(54.69±7.42)次/min(P<0.001)。低频功率(LF)无明显变化(P=0.4783);高频功率(HF)由(965.93±861.05)ms2升至(1282.43±1119.06)ms2;LF/HF由2.00±1.11降至1.65±0.85;总功率(TP)由(12046.91±14863.16)ms2升至(21161.84±22321.06)ms2;超低频功率(ULF)、极低频功率(VLF)明显升高;HFnorm、LFnorm明显降低,差异均有统计学意义(P<0.001)。HF和LF/HF的变化与干预次数无相关性。结论每周1次0.15 MPa的高压氧干预可提高海军青少年航空学校学生的副交感神经活性,增强自主神经功能的调节能力,进一步调节其自主神经平衡。
Objective To observe the changes in autonomic function in Naval Junior Aviation School(NJAS)students under 0.15 MPa hyperbaric oxygen(HBO)intervention,and to provide a reference for health maintenance in adolescents.Methods 42 NJAS students voluntarily signed up for the research.The HBO intervention was performed by pressurizing cabin air to 0.15 MPa(1.5 ATA)in 5 min,lasting for 60 min,during which period the students were continuously breathing pure oxygen by face masks,and then reducing cabin air pressure to normal in 5 min before the students exiting the cabin.The intervention was once a week and continued for seven weeks.Electrocardiograms were collected before and after the HBO intervention,and heart rate variability(HRV)data were obtained using frequency domain analysis to analyze the changes in autonomic function before and after the intervention.Results After 0.15 MPa HBO intervention,the participants’fastest heart rate decreased from(89.81±15.40)beats/min to(84.44±15.36)beats/min,and the slowest heart rate decreased from(58.02±8.49)beats/min to(54.69±7.42)beats/min(P<0.001);low frequency(LF)power did not change significantly(P=0.4783);high frequency(HF)power increased from(965.93±861.05)ms2 to(1282.43±1119.06)ms2;LF/HF decreased from(2.00±1.11)to(1.65±0.85);total power(TP)rose from(12046.91±14863.16)ms2 to(21161.84±22321.06)ms2;ultra-low frequency power and very low frequency power were significantly higher;HFnorm and LFnorm were significantly lower,and all the differences were statistically significant(P<0.001);the changes of HF and LF/HF did not correlate with the times of interventions.Conclusions The 0.15 MPa HBO intervention once a week can increase parasympathetic activity,enhance the ability of adjusting autonomic function,and regulate the balance in autonomic nervous system in NJAS students.
