Cardiac arrest, respiratory arrest and loss of consciousness are the most urgent dangerous situations in clinic. Cardiopulmonary resuscitation (internationally known as CPR) and China (ZGCPR) are the first-aid measures taken in this critical situation.
Cardiopulmonary resuscitation simulator
The cardiopulmonary resuscitation simulator consists of a human model and a cardiopulmonary resuscitation controller. The structure of the mannequin is: replaceable hair, replaceable face, replaceable neck skin, left hand, right hand, abdominal structure, thoracoabdominal contact system, chest pressure plate, lung sac, lower limbs, abdominal sensor, lung sac pad, compression spring, air inlet and outlet device of lung sac, chest skin, etc.
It almost triggers a heart arrest.
1, sudden loss of consciousness, patients fainted on various occasions. 2, pale or cyanosis. 3. Pupils are dilated. 4. Some patients may have transient convulsions, accompanied by head-eye deviation, and then the muscles of the whole body become soft. Heartbeat or respiratory arrest should be judged comprehensively, but because time is precious, we can judge consciousness first and then make further judgment.
First, judge consciousness and airway patency.
(a) to determine whether the patient is conscious.
(2) Call for help: Once it is preliminarily determined that the patient is in a coma, people around him should be immediately called to assist in the rescue.
(3) Put the patient in a proper position: the correct rescue position is supine position. The patient's head, neck and trunk are straight without distortion, and his hands are placed on both sides of the trunk.
(4) Clear the respiratory tract: chin lifting method (or chin lifting method): put one hand on the forehead to make the head lean back, and put the index finger and middle finger of the other hand near the mandible or mandibular angle to lift the mandible (mandible).
(5) Judging breathing: After the respiratory tract is clear, whether breathing exists can be clearly judged.
Second, chest compressions
(1) Pressing position: the middle position of the two phalanges on the sternal notch (xiphoid process of the chest) or the level of the connecting line of the nipple in the middle of the chest.
(2) Pressing depth: at least 5CM.
Three. B —— Clearing respiratory tract (airway open surgery)
(a), jaw lifting (medical staff suspected of trauma using jaw pushing method).
Four. Artificial mouth-to-mouth breathing:
(1) Mouth-to-mouth artificial respiration: Mouth-to-mouth artificial respiration should be performed after the respiratory tract is clear and it is judged that the patient is not breathing.
(2) Mouth-to-mouth artificial respiration and mouth-to-mouth artificial respiration: Mouth-to-mouth artificial respiration can be used when the patient's teeth are closed and his mouth is seriously damaged. When rescuing a baby, because the baby's mouth and nose openings are small and close to each other, the rescuer can stick his mouth to the baby's mouth and nose openings for mouth-to-mouth breathing.
Verb (abbreviation for verb) artificial circulation
(a) to determine whether the patient has a pulse or other signs of breathing.
(2) Chest compression
In China, due to the low popularization rate of cardiopulmonary resuscitation technology, in the event of accidental injuries and acute diseases, due to the lack of personnel who know first aid at the scene of the accident, the wounded and sick are often unable to get timely and correct on-site rescue, thus delaying valuable rescue time, increasing the pain of the wounded and sick, and even causing avoidable disability or death. Therefore, cardiopulmonary resuscitation (CPR) is a first-aid technique that everyone should and must master. The main function of CPR 10480 system is according to the American Heart Association (AHA)20 10 International Cardiopulmonary Resuscitation (CPR)&; Cardiovascular first aid (ECC) guide, the core module of which consists of application software and full-body dummy, is a super-new generation product for the training of teachers and students in social cardiopulmonary resuscitation training institutions, medical colleges and medical and health systems. It is convenient for administrators to manage students' information and provide practical, effective and detailed teaching and training tools.
■ Simulated vital signs: changes of pupil and carotid artery.
■ The airway is clear.
■ Cardiopulmonary Resuscitation: According to the American Heart Association (AHA)20 10 International Cardiopulmonary Resuscitation (CPR)&; Cardiovascular first aid (ECC) guidelines are designed in a standard way, and can be used for artificial respiration and cardiac compression, with Chinese voice or English prompts throughout. The standard airway is open, the real-time operation curve is displayed, the operation language is correct or wrong, the statistical data is printed, and the training and assessment methods can be selected.
■ Student management: recording and playing back operational statistical reports, exercises and evaluations.
CPR 10480 Detailed Function Introduction
CPR 10480 cardiopulmonary resuscitation simulator
■ The simulated human body has obvious anatomical features, real hand feeling, uniform skin color, realistic shape and beautiful appearance. ■ Simulated vital signs: 1) In the initial state, the simulated human pupil is dilated and the carotid artery has no pulsation. 2) In the process of compression, the passive pulsation of human carotid artery is simulated, and the pulsation frequency is consistent with the compression frequency. 3) After the rescue is successful, the simulated human pupil returns to normal and the carotid artery pulsates spontaneously. 4) Pupillary dilation and carotid pulse can be turned on and off by a switch. ■ Artificial respiration and cardiac compression can be performed. The standard airway can be opened and the airway indicator light is on. ■ Three operation modes: cardiopulmonary resuscitation training, mode assessment and actual combat assessment. 1) mode 1: cardiopulmonary resuscitation training, which can be used for pressure blowing training. 2) Mode 2: Mode assessment: within the set time, press and blow 30: 2 correctly according to the international cardiopulmonary resuscitation standard 20 10 to complete five cycles. 3) Mode 3: Actual combat assessment. Teachers can set their own operating time range, operating standards, cycle times, operating frequency and pressure-blowing ratio.
Controller display screen function: ■ Electronic monitoring: Electronic indicator light displays and monitors the opening and pressing parts of airway. Correct counting and wrong counting of artificial respiration and chest compressions. ■ Voice prompt: Chinese voice prompt runs through the training and assessment, which can turn on and off the voice and adjust the volume. ■ The bar code shows the blowing amount: the correct blowing amount is 500 ~ 600 ml-1000 ml:1) If the blowing amount is too small, the bar code is yellow. 2) When the blowing volume is appropriate, the bar code is green. 3) When the blowing volume is too large, the bar code is red. 4) The indicator light that the tidal volume blown in is too fast or too large, causing gas to enter the stomach; Digital counting display; Error language prompt; ■ The bar code shows the pressing depth, and the correct pressing depth is 5-6 cm: 1) If the pressing depth is too small, the bar code will be yellow. 2) When the pressing depth is appropriate, the bar code will be green. 3) When the pressing depth is too large, the bar code is red. ■ You can set the operation time in seconds by yourself. ■ Operating frequency: latest international standard: at least 100 times/minute; You can also set your own values.
