The structure of the hyperbaric oxygen chamber was introduced, and the application of automatic control system to the chamber was discussed from the aspects of the function and information system. The automatic control system can be used for monitoring and control of equipment condition, operation flow and performance data during hyperbaric oxygen therapy, which enhances the efficiency and safety of hyperbaric oxygen chamber.

Objective To observe the clinical effect of combining hyperbaric oxygen (HBO) with repeated transcranial magnetic stimulation (rTMS) in the treatment of vascular cognitive impairment (VCI).Methods A total of 56 hospitalized VCI patients were randomly divided into an HBO+rTMS group (n =25) and an rTMS group (n =27).The patients of both groups were given routine medication,rehabilitation and rTMS treatment,while the HBO+rTMS group was additionally provided with HBO.The mini mental state examination (MMSE),the Montreal cognitive assessment (MoCA),the Lo Winston occupational therapy cognitive assessment (LOTCA) and the modified Barthel index (MBI) were used to evaluate the cognitive function of both groups before and after 4 weeks of treatment.Results Before the treatment there were no significant differences between the two groups in any of the average measurements.After the treatment,significant improvement was observed in the average MMSE and MBI scores in both groups,with significantly greater improvement in the HBO+rTMS group.After the treatment,all the average subscores except that of naming and the total MMSE score of the rTMS group had improved significantly,together with all the average sub-scores and total scores of the HBO+rTMS group.After the treatment the average visual space and execution,abstraction,delayed recall,orientation and the total MoCA score of the HBO+rTMS group were all significantly higher than those of the control group.Conclusion HBO combined with rTMS can improve cognitive function and the life quality of VCI patients.

Objective To explore the effect and safety of radiotherapy post operation combined with hyperbaric oxygen in treatment of keloid .Methods From Jan .1st 2015 to Dec .30th 2016 ,pa-tients with keloid in Plastic Surgery Hospital of Beijing Union Medical College and Navy General Hos -pital were selected and randomly divided into the radiotherapy post operation group and radiotherapy post operation combined with hyperbaric oxygen group .Adverse reactions of both groups of patients during treatment were recorded and calculated .The Vancouver scar scale was used to evaluate treat -ment effect of both groups of patients ;The clinical effect and the recurrence rate of both groups were observed .Results Compared with before treatment ,the Vancouver scar scale scores of both groups of patients after treatment was decreased significantly ,but patients in radiotherapy post operation com-bined with hyperbaric oxygen gorup decreased more significantly (P < 0 .05) .Compared with postoper-ative radiotherapy group ,the total efficiency of patients in radiotherapy post operation combined with hyperbaric oxygen gorup improved more significantly ( P < 0 .05) ,and the recurrence rate after 12 months and 18 months was significantly lower (P < 0 .05) ,and the adverse reaction rate had no signif-icant difference (P > 0 .05) .Conclusions Radiotherapy post operative combined with hyperbaric oxy-gen in the treatment of keloids is better than postoperative radiotherapy alone ,with low recurrence rate and good safety .It may become a new choice for keloid treatment .
