▎ LCD color display: artificial respiration and chest compression, simulated heart beat display, simulated electrocardiogram display;
▎ Simulate standard airway opening;
▎ When artificial hand position chest compression:
1. The dynamic bar code indicator shows the pressing depth: the correct pressing depth (5-6cm area) is displayed by the green light of the bar code, the pressing depth is not enough (less than 5cm) is caused by the yellow bar code, and the pressing depth is too deep (greater than 6cm) by the red bar code indicator. Dynamic feedback shows the depth of CPR compression;
2. LCD count display; detailed records of the specific reasons for pressing errors (excessive pressing force, too small pressing force, incorrect pressing position and correct number of times);
3. Language prompts: Chinese voice prompts, detailed reasons for pressing errors, so that the trainer can correct them in time;
▎ When breathing (blowing) with artificial mouth:
1. The dynamic bar code indicator shows the tidal volume: the correct tidal volume (500ml~600ml-1000ml) is displayed by the green light of the bar code, and the tidal volume blown in is too small or too large, respectively, moved by the bar code yellow or bar code red indicator light. Feedback display tidal measurement;
2. Counting display: record the specific reasons of blowing errors in detail (according to the number of times that the blowing volume is too large, the blowing force is too small, and the blowing is correct);
3. Language prompts: Chinese voice prompts, detailed reasons for blowing errors, so that the trainer can correct them in time;
▎ The ratio of compression to artificial respiration: 30:2 (single or double);
▎ Operation cycle: effective 30 times of pressing and 2 times of manual air blowing, 30:2 CPR operation in five cycles;
▎ Operating frequency: 2020 international standard: at least 100~120 times/min;
▎ Mode of operation: training operation; assessment operation (popular assessment, custom assessment);
▎ Operation time: time in seconds;
▎ Language setting: You can set the language prompt setting and prompt volume adjustment setting; or turn off the language prompt setting;
▎Score printing: The operation result can be thermally printed with long and short transcripts;
▎ Check pupil response: before the assessment operation and after the completion of the assessment procedure, it simulates the true manifestation of the automatic dynamic change process of pupil dilation and shrinkage;
▎ Check the carotid artery response: touch and check by hand to simulate the automatic carotid artery pulsation response during the pressing operation; and the true manifestation of the carotid artery automatic pulsation response after the completion of the assessment program.
