Simulation of an electro-mechanical resuscitation device for cardiopulmonary resuscitation

Application of cardiopulmonary resuscitation to people suffering from cardiac arrest has become an effective way of increasing chances of survival. Current CPR is done manually, however new electro-mechanical resuscitation devices are capable of providing chest compressions at a constant rate and depth, even when the patient is being transported. These new devices give the possibility to generate different compression waveforms additional from the sinus shape given under manual compressions and at different rates. For the exploration of this aspect a simulation system is presented, based on a mathematical model and a simulation engine. This system is capable of generating different scenarios simultaneously. Several waveforms were introduced into the model and the cardiac output of each shape is presented. Results show that a trapezoidal waveform gave better performance in terms of cardiac output.
