ABSTRACT
Objective To evaluate the effect of type WIYIS-6/90 plateau oxygen generating vehicle on the high altitude spot. Methods Totally 20 male soldiers during field training at 4 280 m altitude were involved in this trial. They were given administration of oxygen inhalation at 2 L/min by nasal cannula. Blood pressure, heart rate, blood oxygen saturation, vital capacity, left and right hand strength, digit span and discriminative reaction time were detected before and after oxygen inhalation for 20 minutes and finished for 10 minutes. Results After oxygen inhalation for 20 minutes, blood oxygen saturation, vital capacity, left and right hand strength, digit span and correct times increased and heart rate decreased compared with before oxygen inhalation (P<0.05,or P<0.01).Stopping oxygen inhalation for 10 minutes,vital capacity and right hand strength increased and response time decreased(P<0.05,or P<0.01).Conclusion Using type WIYIS-6/90 plateau oxygen generating vehicle for oxygen supply at high altitude can improve brain-body function and promote work ability.
ABSTRACT
OBJECTIVE@#To investigate the prevalence of chronic mountain sickness (CMS) and its predisposing factors in Pamirs plateau and analysis clinical feature and risk factors.@*METHODS@#Eight hundred and twenty-four individuals in Pamirs plateau were surveyed used Qinghai CMS scoring system. Demographics, BP, SaO, heart rate and specified symptoms of CMS were recorded, Hb level was estimated.@*RESULTS@#Overall CMS prevalence was 22.08%, including 21.84% mild and 0.24% moderate without severe patient. Gender, nation, age, immigration time, altitude, occupation and accommodation mode were risk factors for CMS (<0.05 or <0.01), CMS prevalence was higher than HAPC rate both in male and female (χ=90.59 and 44.13, <0.01). Multiple linear regression analysis showed age, BMI, SaO and systolic pressure correlated with CMS (<0.01).@*CONCLUSIONS@#Chronic mountain sickness prevalence in Pamirs plateau is rather high but high altitude polycythemia prevalence is low, so the disease type is high altitude deterioration. Work and exercise more reasonable to avoid overtiredness, oxygen inhalation to raise blood oxygen saturation, control blood pressure and resting therapy can improve CMS symptom and decrease prevalence.

<p><b>OBJECTIVE</b>To analysis deacclimatization symptom scores of 159 youth from Karakoram and Tibet Ali area, and provide the basis for the development of relevant prevention and control measures.</p><p><b>METHODS</b>Using the method of epidemiological symptoms questionnaire, 18 symptoms of 190 youth who returned to the plain area from the different plateau were investigated. The symptom scores of different altitude, age, the time of staying, different units, continuous or intermittent stage and education were surveyed.</p><p><b>RESULTS</b>Deacclimatization symptom scores among 5,000 meter groups were significantly higher than those of 4,300 meter and 3,700 meter group (P < 0.05, P < 0.01). There was no significant difference between the 4,300 meter group and the 3,700 meter group (P > 0.05). There were significant differences among the stayed personnel (different age, position, unit, education, time, continuous or intermittent) (P < 0.01). There was significant difference between the continuous defended the group and intermittent group (P < 0.01).</p><p><b>CONCLUSION</b>Deacclimatization symptom scores were related to the plateau exposure time, altitude, workload, plateau continued exposure. The older, the longer exposure, the higher altitude, the greater workload at plateau were showed higher deacclimatization symptom score.</p>

The incidence of deacclimatization to high altitude syndrome (DAHAS) prevailed up to 80% in highland troops, and 100% in manual workers, and severe DAHAS could significantly affects patients' health, work and life. So it is imperative to develop effective prevention and treatment measures for DAHAS. The present review analyzes effective prophylactic and therapeutic measures against DAHAS, implemented at our hospital.
