▎ 3.5-inch LCD screen display.
▎ The simulated human has obvious anatomical features, real hand feeling, uniform skin color, realistic shape and beautiful appearance.
▎ Simulated vital signs:
.In the initial state, the simulated human pupils are dilated, and the carotid artery is not pulsating.
During the compression process, the passive pulsation of the human carotid artery is simulated, and the pulsation frequency is consistent with the compression frequency.
After the rescue is successful, the simulated human pupil returns to normal, and the carotid artery pulsates spontaneously.
.Pupillary zoom and carotid artery pulsation can be turned on and off by a switch.
▎ Artificial respiration and extracardiac compression can be performed. Standard airway opening can be performed, and the airway indicator light turns on.
▎ Three operation modes: CPR training, mode assessment and actual combat assessment can be carried out.
.Method 1: CPR training, which can be used for compression and blowing training.
.Method 2: Mode assessment, within the set time, according to the 2020 International Cardiopulmonary Resuscitation Standard, the correct number of presses and blows are 30:2, and 5 cycles are completed.
.Method 3: actual combat assessment, the teacher can set the operating time range, operating standards, cycle times, operating frequency, and the ratio of pressing and blowing.

【Controller display function】

▎ Electronic monitoring: The electronic indicator shows and monitors the airway opening and compression parts. Counting the correct number of times of artificial respiration and chest compressions and counting the wrong number of times.
▎ Voice prompt: Chinese voice prompt during training and assessment, you can turn on and off the voice and adjust the volume.
▎ Text prompts: Chinese text prompts throughout the training and assessment.
▎ Bar code shows the blowing volume: the correct blowing volume is 500~600ml-1000ml:
.When the air volume is too small, the bar code is yellow.
.When the blowing volume is right, the bar code is green.
.When the blowing volume is too large, the bar code is red.
.The tidal volume blown in is too fast or too large, causing the gas to enter the stomach. The indicator light shows; the digital count display; the wrong language prompt;
▎ The bar code shows the pressing depth, the correct pressing depth is 5-6cm:
.When the pressing depth is too small, the bar code is yellow.
.When the pressing depth is appropriate, the bar code is green.
.When the pressing depth is too large, the bar code is red.
▎ The operation time can be set by yourself, in seconds.
▎ Operating frequency: The 2020 standard is at least 100~120 times/min.
▎ Power status: 220V power supply is adopted, and the output power is 12V after being stabilized by a voltage stabilizer. (Optionally install a lithium battery, suitable for direct use without an external power supply.)

【Printing function】

▎ Print the operation process after the operation is over.
▎ The content of the transcript covers the operation method, consciousness judgment, emergency breathing, pulse check, breathing check, removal of foreign objects, operation frequency, pressing and blowing ratio, number of cycles, the number of pressing and blowing in each cycle operation, and correct pressing/ The number of errors, the reasons and times of pressing errors, the reasons and times of correct/error blowing, the reasons of incorrect blowing, setting time, operating time and assessment.
