© 2018 IEEE. Automatic mechanical ventilator is a standard equipment used to provide an artificial ventilation to a patient who has a respiratory system problem and can be commonly seen in the general ICU ward. Its function is to supply airflow into lung during inspiration and remove air out from lung during expiration phase which quite complicated and user always need a routine practice in order to understand all ventilation parameter settings. In this paper, we propose a simplified ventilator circuit by using model simulation in order to use as a simple tool in the ventilation parameter study. Our model is intending to use with a simple rubber test lung bag in VCV mode (V T , RR, T I ) with a pause time setting addition. As a preliminary, all main ventilation waveforms obtain from this modified model provide us a useful information for a further study in the future which will be focused on an another basic ventilation mode such as PCV or IMV with PEEP/CPAP.
