ABSTRACT
OBJECTIVE@#Invent a simulator which provides a simulation of heart rate and respiratory rate to the intelligent sleep monitoring devices based on precision pressure sensors.@*METHODS@#The simulator was composed of control part and simulated silicone doll. The simulated silicone doll contains heartbeat simulator and breathing simulation airbag. Heartbeat and breathing combination pressure signal can be produced according to frequency set values. Frequencies of pressure signal of the simulator were compared with the monitoring results of intelligent sleep monitoring devices with known accuracy to verify the frequency accuracy of pressure signal of the simulator. Verified the repeatability and stability of the simulator with a stopwatch.@*RESULTS@#The heart rate of the simulator was with in ±2 beats per minute of the monitoring results of intelligent sleep monitoring devices and the respiratory rate of the simulator was with in ±2 times per minute of the monitoring results. The repeatability and stability of the simulator was better than ±5% according to results with a stopwatch.@*CONCLUSIONS@#It's practicable to use the simulator which provides a simulation of heart rate and respiratory rate to the accuracy test of the intelligent sleep monitoring devices based on precision pressure sensor.
ABSTRACT
Object To analyze and evaluate the result of using high fidelity Human Patient Simulator in the training of cardiopulmonary resuscitation.Methods Use SimMan4000 human analogue of Norway Laerdal company and the high fidelity Human Patient Simulator ofMedical Education Technology Incorporation,210 doctors were trained,and training contented contain cardiopulmonary resuscitation,malignant arrhythmia and respiratory failure.then,score was gaven by computer.The freeback questionnaire of trained residents were added up.Result The average score of artificial respiration and press chest outside were 65.41?24.36 and 75.62? 24.65 before training respectively,the scores were 88.37?22.45 and 88.23?21.46 after training respectively.The ability of cardiopulmonary resuscitation raised obviously(P
